Boosting hydrogen and chemicals production through ethanol electro-reforming on Pt-transition metal anodes

引用

Journal of Energy Chemistry 2022年第7期31卷 394-406,I0011页

作者： Alberto Rodríguez-Gómez Fernando Dorado Paula Sánchez Ana Raquel de la osa Chemical Engineering Department Faculty of Chemical Sciences and TechnologyUniversity of Castilla-La Mancha

The aim of this work is to boost the combined hydrogen and added-values compounds generation(acetaldehyde, acetic acid and ethyl acetate) through ethanol electrochemical reforming using bimetallic anodes. In particular, the influence of the secondary metal on the electrochemical performance as well as on the product distribution was studied. For that purpose, Pt X/C electrocatalysts(where X corresponds to Cu, Co, Ni and Ru) were synthesized by the modified polyol method and tested in both half-cell and proton exchange membrane(PEM) cell configurations. Characterization results showed that incorporation of Ni and Co into the Pt matrix enhances the morphological properties of the material, providing smaller crystallite sizes, higher active surface areas and hence, better dispersion when comparing to Ru and Cu-based electrocatalysts. Ethanol oxidation reaction(EOR) was evaluated by cyclic, linear voltammetry and chronopotentiometry assays. Pt Co/C and Pt Ni/C exhibited the highest electrocatalytic activity at high polarization levels, which translate into an improvement of more than 30%(up to 1050 m A cm^(-2)) in the hydrogen production and chemical yields. On the other hand, Pt Ru/C results more advantageous for a lower potential interval(<0.85 V) promoting the acetic acid production despite sacrificing ethanol conversion. Pt Cu/C presented the lowest results in both electrochemical performance and product distribution. Such differences in the electrochemical performance can be rationalized in terms of the synergistic effect between both metals(particle size distribution, grade of dispersion and hydrophilic behavior), which demonstrate that the incorporation of a different secondary metal plays an essential role in the EOR development.

High-spin structure in ^(187)Pt

High-spin states in 187Pt were studied via the 173Yb(18O,4n) reaction. Rotational bands based on the νi13/2,ν7/2-[503],νi213/2νj,ν3/2-[512] and ν1/2-[521] configurations were observed,and interpreted within the framework of the cranked shell model. The TRS calculations show that the νi13/2 band has an appreciable negative γ deformation,and the negative-parity bands tend to have a near prolate shape with small positive γ values. Experimental values of B(M1) /B(E2) ratios have been extracted and compared with theoretical values from the semi-classical D-nau and Frauendof approach,strongly suggesting a low frequency πh9/2 alignment in the ν7/2-[503] band.

A ferrocene-mediated anti-interfering glucose biosensor based on glutin and cellulose acetate

引用

High Technology Letters 2006年第3期12卷 263-266页

作者：吴宝艳 Li Jing Shi Haibin Huang Jiadong Anzai Jun-ichi osa Tetsuo Chen Qiang College of Life Seienees Nankai University Tianjin 300071. P.R. China Graduate School of Pharnlaceutical Sciences Tohoku University Sendai 9808578 Japan

A ferrocene-mediated glucose biosensor removing interference of ascorbic acid and uric acid was developed by coating of ferrocene, glutin and cellulose acetate on screen-printed gold electrode surface. The results show that it can detect glucose sensitively in the presence of uric acid and ascorbic acid, and also suppress the leakage velocity of ferrocene. Compared to the currents of the pretreated electrode, it decreases the current of uric acid and ascorbic acid by 99.4% and 98.8% at 400 mV, respectively, with a dynamic range of 0-30 mM for glucose, sensitivity of 30.73 nA/mM, response time of 10 s, and correlation coefficient of 0.9988.

Structure evolution along the yrast-line in ^(101)Pd

作者：周厚兵周小红张玉虎 Oshima M. Toh Y. Koizumi M. osa A. Hatsukawa Y Institute of Modern Physics Chinese Academy of Sciences Graduate University of Chinese Academy of Sciences Japan Atomic Energy Agency TokaiIbaraki 319-1195Japan

High-spin states in ^101Pd have been investigated experimentally via the ^76Ge（^28Si, ^3nγ）^101pd reaction. The previously known bands based on the d5/2 and h11/2 neutron orbitals have been extended to higher-spin states, and two new structures have been observed. Spin and parity were assigned to the levels on the basis of the experimental results of the angular distribution of y rays deexciting the oriented states. For the ground-state band, the E-COS （E-Gamma Over Spin） curve strongly suggests a structure transition from vibration to rotation while increasing spin.

A standard in-beam y-spectroscopy experiment for ^188Pt is performed via the ^176yb（^18O, 6n） reaction at beam energies of 88 and 95 MeV, and the level scheme for ^188Pt is established. Prolate and oblate shape coexistence has been demonstrated to occur in ^188Pt by applying the projected shell model. The rotation Mignment of i13/2 neutrons drives the yrast sequence changing suddenly from prolate to oblate shape at angular momentum 1Oh, indicating likely a new type of shape phase transition along the yrast fine in ^188Pt.

Observation of High-j Two-Quasiparticle Bands in Odd-Odd ^174Re

Chinese Physics Letters 2005年第11期22卷 2788-2791页

作者：张玉虎郭松周小红马龙 Oshima M. Toh Y. Koizumi M. osa A. Kimura A. Hatsukawa Y. Sugawara M. Kusakari H. Institute of Modern Physics Chinese Academy of Sciences Lanzhou 730000 Graduate School of Chinese Academy of Sciences Bejing 100039 Japan Atomic Energy Research Institute Tokai-mura Ibaraki 319-1195 Japan Chiba Institute of Technology Narashino Chiba 275-0023 Japan Chiba University Inage-ku Chiba 263-8512 Japan

High spin states in ^174Re have been investigated via the ^152Sm （^27 Al, 5nγ） ^174Re reaction. Gamma-ray excitation functions, x-γ and γ-γ coincidences have been measured. Two rotational bands built on the πh9/2 × vi13/2 and πh11/2 × vi13/2 configurations have been identified and extended up to high-spin states. The relative spin and parity of the band levels have been unambiguously fixed due to observations of several inter-band transitions. Both the bands show the low-spin signature inversion, which is consistent with systematic expectations for the high-j two-quasiparticle bands in the A = 170 mass region.
