Electrocatalytic oxygen evolution reaction(OER)has been recognized as the bottleneck of overall water splitting,which is a promising approach for sustainable production of H_(2).Transition metal(TM)hydroxides are the most conventional and classical non-noble metal-based electrocatalysts for OER,while TM basic salts[M^(2+)(OH)_(2-x)(A_(m^(-))_(x/m),A=CO_(3)^(2−),NO_(3)^(−),F^(−),Cl^(−)]consisting of OH−and another anion have drawn extensive research interest due to its higher catalytic activity in the past decade.In this review,we summarize the recent advances of TM basic salts and their application in OER and further overall water splitting.We categorize TM basic salt-based OER pre-catalysts into four types(CO_(3)^(2−),NO_(3)^(−),F^(−),Cl^(−)according to the anion,which is a key factor for their outstanding performance towards OER.We highlight experimental and theoretical methods for understanding the structure evolution during OER and the effect of anion on catalytic performance.To develop bifunctional TM basic salts as catalyst for the practical electrolysis application,we also review the present strategies for enhancing its hydrogen evolution reaction activity and thereby improving its overall water splitting performance.Finally,we conclude this review with a summary and perspective about the remaining challenges and future opportunities of TM basic salts as catalysts for water electrolysis.

Simultaneous utilization of electro-generated O_(2)and H_(2)for H_(2)O_(2)production:An upgrade of the Pd-catalytic electro-Fenton process for pollutants degradation

引用

Chinese Journal of Chemical Engineering 2022年第4期35卷 363-368页

The Electro-Fenton(EF)process is one of the promising advanced oxidation processes(AOPs)for environmental remediation.The H_(2)O_(2) yield of EF process largely determines its performance on organic pollutants degradation.Conventional Pd-catalytic EF process generates H_(2)O_(2) via the combination reaction of anodic O_(2) and cathodic H;.However,the relatively expensive catalyst limits its application.Herein,a hybrid Pd/activated carbon(Pd/AC)-stainless steel mesh(SS)cathode(PACSS)was proposed,which enables more efficie nt H_(2)O_(2)generation.It utilizes AC,the support of Pd catalyst,as part of cathode for H_(2)O_(2) generation via 2-electron anodic O_(2) reduction,and SS serve as a current distributor.Moreover,H_(2)O_(2) could be catalytically decomposed upon AC to generate highly reactive·OH,which avoids the use of Fe;.Compared with conventional Pd catalyst,H_(2)O_(2) concentration obtained by PACSS cathode is248.2%higher,the O_(2)utilization efficiency was also increased from 3.2%to 10.8%.Within 50 min,26.3%,72.5%,and 94.0%H_(2)O_(2) was decomposed by Pd,AC,and Pd/AC.Fluorescence detection results implied that Pd/AC is effective upon H_(2)O_(2) activation for·OH generation.Finally,iron-free EF process enabled by PACSS cathode was examined to be effective for reactive blue 19(RB19)degradation.After continuous running for 10 cycles(500 min),the PACSS cathode was still stable for H_(2)O_(2)generation,H_(2)O_(2)activation,and RB19 degradation,showing its potential application for organic pollutants degradation without increase in the running cost.

为了探究铜掺杂金团簇的结构及特性,依据密度泛函理论对Au_(n) Cu^(0/-)(n=1~9)团簇的结构、稳定性、电子及光学性能进行了系统分析。基于卡利普索结构预测程序,在B3LYP/Lanl2dz水平下优化得到了不同尺寸的基态结构。研究表明,除Au7 Cu和Au8 Cu-呈现三维结构外,其它尺寸下的基态均呈现二维平面结构。而且,Au_(n) Cu^(0/-)的基态可通过在Au_(n)-1 Cu^(0/-)基态基础上添加一个Au原子得到。稳定性分析确定了Au_(5) Cu和Au_(2) Cu-团簇在各自体系中拥有相对强的稳定性。磁性分析发现,闭壳层电子结构体系的总自旋磁矩为零;开壳层电子结构体系分别具有1μB的总磁矩。分析极化率表明,Au_(9) Cu和Au_(9) Cu-团簇对外场的各向异性响应最强,AuCu和Au_(3) Cu-团簇对外场的各向异性响应最弱。AdNDP分析发现,众多σ键连通了整个分子骨架,促进了整个团簇的稳定。基于Multiwfn程序,拟合的光电子能谱、红外谱、拉曼谱和紫外可见光谱可为实验上鉴别Au_(n) Cu^(0/-)团簇的结构提供帮助。

Fabrication of easily recyclable photocatalyst with excellent photocatalytic activity for degradation of organic pollutants in wastewater is highly desirable for practical application.In this study,a novel ternary magnetic photocatalyst BiVO_(4)/Fe_(3)O_(4)/reduced graphene oxide(BiVO_(4)/Fe_(3)O_(4)/rGO)was synthesized via a facile hydrothermal strategy.The BiVO_(4)/Fe_(3)O_(4) with 0.5 wt%of rGO(BiVO_(4)/Fe_(3)O_(4)/0.5%rGO)exhibited superior activity,degrading greater than 99%Rhodamine B(RhB)after 120 min solar light radiation.The surface morphology and chemical composition of BiVO_(4)/Fe_(3)O_(4)/rGO were studied by scanning electron microscopy,X-ray diffraction,X-ray photoelectron spectroscopy,UV–visible diffuse reflectance spectroscopy,Fourier transform infrared spectroscopy,and Raman spectroscopy.The free radicals scavenging experiments demonstrated that hole(h^(+))and superoxide radical(O_(2)•^(−))were the dominant species for RhB degradation over BiVO_(4)/Fe_(3)O_(4)/rGO under solar light.The reusability of this composite catalyst was also investigated after five successive runs under an external magnetic field.The BiVO_(4)/Fe_(3)O_(4)/rGO composite was easily separated,and the recycled catalyst retained high photocatalytic activity.This study demonstrates that catalyst BiVO_(4)/Fe_(3)O_(4)/rGO possessed high dye removal efficiency in water treatment with excellent recyclability from water after use.The current study provides a possibility for more practical and sustainable photocatalytic process.

针对油田复杂环境下管材发生腐蚀失效问题,采用SEM、EDS及XRD对试样在不同Cl^(-)浓度下(0 g/L、20 g/L、40 g/L、80 g/L和120 g/L)腐蚀后的表面形貌、腐蚀产物的成分及物相组成进行分析,通过电化学测试,研究了不同Cl^(-)浓度下SRB对抗微生物腐蚀管材性能的影响。结果发现,Cl^(-)浓度为20 g/L时最适宜SRB生长,但此时SRB对抗微生物腐蚀管材的腐蚀性最小,此后随着Cl^(-)浓度升高,生物膜减少,腐蚀速率增大;当Cl^(-)浓度分别为0 g/L、20 g/L时,在腐蚀产物中检测出FeS和Fe_(3)(PO_(4))_(2),且腐蚀均受阴极反应控制。因此,在不同Cl^(-)浓度下,SRB对抗微生物腐蚀管材性能的影响与试样表面形成的生物膜有关,随着Cl^(-)浓度的增加,SRB对抗微生物腐蚀管材腐蚀作用减小。

Sustained proteinuria is an independent risk factor leading to kidney fibrosis and end-stage renal fail-ure.Over-reabsorption of filtered proteins,notably albu-min,has been proved to trigger interstitial inflammation and fibrosis in proteinuric renal disease.Cubilin,an endo-cytic receptor expressed on the renal tubular brush bor-der,is responsible for albumin reabsorption in physiologic condition.However,little is known about whether it is required for activation of tubular cells induced by albu-min overload.In this work,we investigated the change of cubilin expression and its potential role in albumin-induced up-regulation of chemokines synthesis in vivo and in vitro.Twenty-six patients with nephrotic syndrome were enrolled in this study.Proximal tubule uptake of albumin,expression of apical membrane cubilin and infiltrating cells in kidney interstitium were determined by immunocytochemistry.In vitro,the transcription of cubilin in HK2 cells after exposure to albumin was ana-lyzed by real-time PCR.Endocytosis of albumin in HK2 cells was examined by fluorescent microscope.The influ-ence of inhibition of cubilin on albumin-induced expres-sions of monocyte chemoattractant protein 1(MCP-1)and regulated upon activation normal T-cell expressed and secreted(RANTES)was investigated by Western blot.The intensity of luminal cubilin and tubular accu-mulation of albumin were significantly increased in nephrotic kidneys.The expression of MCP-1 and RANTES was up-regulated,and there were spatial rela-tionships in localization between these chemokines and cubilin as well as intracellular albumin in kidney tissues.Infiltration of CD-3 and ED-1-positive cells was predom-inant in tubulointerstitial areas displaying signs of increases of cubilin expression and albumin accumula-tion.In vitro,the transcription of cubilin mRNA in HK2 cells was enhanced after 24 h exposure to albumin in a dose-dependent manner.Inhibition of endocytosis of albumin by antisense cubilin nucleotide markedly reduced expression of MCP-1 and RANTES.Cubilin wa

When preparing large monocrystalline silicon materials,severe carbon etching and silicide deposition often occur to the thermal system.Therefore,a suppression method that optimizes the upper insulation structure has been proposed.Assisted by the finite element method,we calculated temperature distribution and carbon deposition of heater and heat shield,made the rule of silicide and temperature distributing in the system,and we explained the formation of impurity deposition.Our results show that the optimized thermal system reduces carbon etching loss on heat components.The lowered pressure of the furnace brings a rapid decrease of silicide deposition.The increase of the argon flow rate effectively inhibits CO and back diffusion.The simulated results agree well with the experiment observations,validating the effectiveness of the proposed method.
