摘要

摘要:将二氧化碳转化为有用的燃料被认为是应对二氧化碳排放增加及其对气候的不良影响的新途径。本文采用简单的电化学氧化还原法制备了Cu2O/聚苯胺(PANI)/不锈钢复合电极，该电极在水溶液中具有CO2还原作用。采用x射线衍射(XRD)、透射电镜(TEM)和循环伏安法对所得电极进行了表征。合成的复合电极表现出优异的电催化活性。Cu2O/PANI/不锈钢基电极(Cu2O/PANI/不锈钢)在0.1 mol/L硫酸钠溶液中还原CO2产生的甲醛产量约为0.505 μmol·L - 1·h-1。

Electrochemical reduction of CO2 on a Cu2O/polyaniline /stainless steel based electrode

Abstract: Reduction of CO2 into useful fuels is regarded as a new way to deal with increasing CO2 emissions and its bad effects on climate. In this report, simple electrochemical oxidation-reduction method has been utilized to prepare Cu2O/polyaniline (PANI)/stainless steel composite electrode, which was identified as a contributor for CO2 reduction in an aqueous solution. X-ray diffraction (XRD), transmission electron microscope (TEM) and cyclic voltammetry technique were carried out to characterize the as-obtained electrode. As-synthesized composite electrode exhibited excellent electrocatalytic activity. The production of formaldehyde that comes from the reduction of CO2 using Cu2O/PANI/stainless steel based electrode (Cu2O/PANI/stainless steel) in 0.1 mol/L sodium sulfate solution is 0.505 μmol·L–1·h–1 approximately.

期刊介绍： The Journal of advanced oxidation technologies (AOTs) has been providing an international forum that accepts papers describing basic research and practical applications of these technologies. The Journal has been publishing articles in the form of critical reviews and research papers focused on the science and engineering of AOTs for water, air and soil treatment. Due to the enormous progress in the applications of various chemical and bio-oxidation and reduction processes, the scope of the Journal is now expanded to include submission in these areas so that high quality submission from industry would also be considered for publication. Specifically, the Journal is soliciting submission in the following areas (alphabetical order): -Advanced Oxidation Nanotechnologies -Bio-Oxidation and Reduction Processes -Catalytic Oxidation -Chemical Oxidation and Reduction Processes -Electrochemical Oxidation -Electrohydraulic Discharge, Cavitation & Sonolysis -Electron Beam & Gamma Irradiation -New Photocatalytic Materials and processes -Non-Thermal Plasma -Ozone-based AOTs -Photochemical Degradation Processes -Sub- and Supercritical Water Oxidation -TiO2 Photocatalytic Redox Processes -UV- and Solar Light-based AOTs -Water-Energy (and Food) Nexus of AOTs
