Electrochemical sensing provides a powerful technological means for the therapeutic drug monitoring of drug-resistant tuberculosis but requires a functionalized electrode to capture the analytes and catalyze their redox reactions.Herein,we construct a nickel-tannic acid supramolecular network(Ni-TA)on the surface of electrospun-derived C-CeO_(2) nanofiber for the sensitive and simultaneous detection of isoniazid(INZ)and hydrazine(HYD).Mechanistic investigations demonstrate that Ni-TA is electronegative and hydrophilic,thus facilitating an efficient mass and electron transfer.Ni-TA/C-CeO_(2) has higher adsorption rate constants(0.091 g mg^(-1)h^(-1)for INZ,and 0.062 g mg^(-1)h^(-1)for HYD)than native C-CeO_(2)(0.075 g mg^(-1)h^(-1)for INZ,and 0.047 g mg^(-1)h^(-1)for HYD).Moreover,Ni-TA/C-CeO_(2)(56Ω)has lower charge transfer resistances than C-CeO_(2)(417Ω).Ni-TA/C-CeO_(2) performs low detection limits and wide linearity ranges for INZ(0.012μmol/L and 0.1-400μmol/L,respectively)and HYD(0.008μmol/L and 0.015-1420μmol/L,respectively),coupled with high selectivity,cycle stability and reproducibility.This research demonstrated the promising applications of Ni-TA/C-CeO_(2) by analyzing human-collected plasma and urine samples.

hydrazine is extremely toxic and causes severe harm to human body.Herein,a novel fluorescent probe 4-oxo-2-styryl-4H-chromen-3-yl thiophene-2-carboxylate(FHT)was synthesized for detecting hydrazine by using natural cinnamaldehyde as starting material.This probe exhibited significantly enhanced fluorescence response towards hydrazine over various common metal ions,anions,and amine compounds.The detection limit of probe FHT for hydrazine was as low as 0.14μmol·L^(-1),significantly lower than that of the threshold value of 0.312μmoi·L^(-1),imposed by the Environmental Protection Agency.Moreover,the proposed probe was able to detect hydrazine within wide pH(5-10)and linear detection ranges(0-110μmol·L^(-1)).This probe was employed for determining trace hydrazine in different environmental water samples.The probe FHT-loaded filter paper strips werea able to conveniently detect hydrazine of low concentration through distinct naked-eye and fluorescent color changes.Importantly,the probe FHT with low cytotoxicitywas successfullyapplied to visualize hydrazine in living Hela cells and zebrafish.

Due to the properties and high reactivity of hydrazine,it is mainly used as rocket fuel not only in its pure form but also in combination with 1,1-dimethylhydrazine and oxidizers(nitrogen tetroxide or nitric acid)forming a self-igniting mixture with oxidizers.Aerozine 50 and UH 25(a mixture of 75%UDMH(unsymmetrical dimethylhydrazine)and 25%hydrazine hydrate)are the best-known hydrazine mixtures with different hydrazine concentrations.The review addresses the use of hydrazine and its derivatives as fuel.hydrazine is employed in fuel cells(with air oxygen as an oxidizer)to generate electrochemical energy for transport vehicles.hydrazine is widely used as monopropellant to design low-thrust rocket engines for orientation and stabilization systems in space vehicles,as well as in energy units.The review also addresses such hydrazine derivatives as methylhydrazine,1,1-dimethylhydrazine,hydrazine monoperchlorate,hydrazine diperchlorate,hydrazine diammonium tetraperchlorate,hydrazine mononitrate,hydrazine dinitrate,hydrazine nitroformate,hydrazine azides,tetrafluorohydrazine,etc.as well as composite propellants,and gel rocket propellants based on hydrazine.The materials in the review can be used as reference information on hydrazine fuels.

The hexavalent chromium(Cr(Ⅵ))would frequently impose inhibition to anaerobic ammonium oxidation(anammox)process,hindering the efficiency of nitrogen removal in wastewater treatment.hydrazine(N2H4),which is an intermediate product of anammox,participates in intracellular metabolism and extracellular Cr(Ⅵ)reduction.However,the roles of N_(2)H_(4)-induced intracellular metabolism and extracellular reduction in nitrogen removal under Cr(Ⅵ)stress remain unclear.The addition of 3.67 mg/L of N2H4 increased the anammox activity by 17%.As an intermediate,N2H4 enhanced anammox metabolism by increasing the heme c content and electron transfer system activity.As a reductant,N_(2)H_(4) accelerated the reduction of c-Cyts-mediated extracellular Cr(Ⅵ)to the less toxic Cr(Ⅲ).Extracellular Cr(Ⅲ)accounts for 74%of the total Cr in a Cr(Ⅵ)-stressed anammox consortia.These findings highlight that N_(2)H_(4)-induced extracellular Cr(Ⅵ)reduction is the dominant mechanism for the survival of anammox consortia.We also found that N_(2)H_(4) increased the production of extracellular polymeric substances to sequester excessive Cr(Ⅵ)and produced Cr(Ⅲ).Taken together,the study findings suggest a potential strategy for enhancing nitrogen removal from ammonium-rich wastewater contaminated with Cr(Ⅵ).

Well-defined platelet-like hydrazine-cadmium tellurite hybrid microcrystals have been synthesized by a solvothermal reaction of cadmium chloride,sodium tellurite,and hydrazine hydrate in a mixed solvent containing n-propylamine and deionized water.The formula of the hybrid platelet-like microcrystals has been proposed based on a combination of powder X-ray diffraction pattern(PXRD),elemental analysis,thermogravimetic analysis(TGA),and X-ray photoelectron spectroscopy(XPS).Controlled thermal decomposition of this hybrid precursor can lead to the formation of porous platelet-like microarchitectures.Pure porous cadmium telluride architectures were obtained by using hydrochloric acid to dissolve CdTeO3 remaining in the sample after thermal decomposition at 450°C.In addition,unique nanoporous tellurium architectures were obtained by using hydrochloric acid to dissolve the amorphous Cd(N2H4)TeO3 formed after thermal decomposition at 300°C,followed by an in situ topotactic reaction between the residual three-dimensional(3-D)skeleton of cadmium telluride nanocrystallites and−23TeO.Brunauer-Emmett-Teller(BET)analysis and a study of the optical properties of these porous cadmium telluride and tellurium materials have also been carried out.

National Science Review 2018年第3期5卷 356-364页

作者： Lei He Binglian Liang Yanqiang Huang Tao Zhang State Key Laboratory of Catalysis Dalian Institute of Chemical Physics Chinese Academy of Sciences University of Chinese Academy of Sciences

hydrazine, a widely used liquid propellant, has the potential to be employed as a hydrogen source in certain instances and has therefore attracted considerable attention; consequently, the complete decomposition of hydrazine with 100% Hselectivity under mild conditions has become the current research focus for catalyst design. In this review, the strategies for the design of efficient catalysts are summarized for complete hydrazine decomposition. The first part of this review introduces the mechanism of hydrazine decomposition, while the second part illustrates the key factors influencing the Hselectivity of nickel catalysts, including the effects of alloying, alkali promoter addition and strong metal–support interactions.Finally, the critical elements of catalyst design employed in industrial applications are analyzed.

The safe and efficient storage and release of hydrogen is one of the key technological challenges for the fuel cell-based hydrogen economy. hydrazine monohydrate has attracted considerable attention as a safe and convent chemical hydrogen-storage material. Herein, we report the facile synthesis of NiPt-CeOx nanocomposites supported by three-dimensional nitrogen-doped graphene hydrogels （NGHs） via a simple one-step co-reduction synthesis method. These catalysts were composition-dependent for hydrogen generation from an alkaline solution of hydrazine. （NisPt5）I-（CeOx）0.B/NGH exhibited the highest catalytic activity, with 100% hydrogen selectivity and turnover frequencies of 408 h^-1 at 298 K and 3,064 h^-1 at 323 K. These superior catalytic performances are attributed to the electronic structure of the NiPt centers, which was modified by the electron interaction between NiPt and CeOx and the strong metal-support interaction between NiPt-CeOx and the NGH.

In this study, we first attempted to discover the optimal configuration of membrane-electrode assemblies(MEAs) used to achieve a high performance of direct hydrazine fuel cells(DHFCs). We have investigated the effect of water management and the electrode thickness on the performance of DHFCs, depending on the hydrophobicity of the gas diffusion layers in the cathode and the catalyst loading in the anode with the carbon-supported Ni, synthesized by a polyol process. With the optimal water management and electrode thickness, the MEA constructed using the as-prepared Ni/C anode catalyst containing the metallic and low oxidative state and ultra-low Pt loading cathode reduced the ohmic resistance and mass transfer limitation in the current-voltage curves observed for the alkaline DHFC, achieving an impressive power performance over 500 mW cm^(–2).

Electro-oxidation of hydrazine shows marcusian electron transfer kinetics

Science China Chemistry 2021年第2期64卷 322-329页

作者： Ruiyang Miao Lifu Chen Richard G Compton Department of Chemistry Physical and Theoretical Chemistry LaboratoryUniversity of OxfordSouth Parks RoadOxfordOX13QZUK

Although hydrazine(N2 H4) oxidation in an electrochemical environment has been of great interest for years,its intrinsic electron transfer kinetics remain uncertain.We report that the phenomenological Butler-Volmer(BV) theory is not appropriate for interpreting the process of hydrazine oxidation for which an astonishingly wide range of transfer coefficients,Tafel slopes and diffusion coefficient have been previously reported.Rather Tafel analysis for voltammetry recorded at Glassy Carbon(GC)electrodes reveals a strong potential dependence of the anodic transfer coefficient,consistent with the symmetric Marcus-Hush(sMH) theory.According to the relationship β=λ+FEf^0/2λ-F/2λ E,the reorganization energy(0.35±0.07 eV) and an approximate formal potential of the rate-determining first electron transfer were successfully extracted from the voltammetric responses.
