摘要
以葡萄糖为原料,利用液体催化燃料电池搭建生物质电解制氢系统,并对磷钼酸催化氧化葡萄糖电解制氢的性能进行分析。结果表明,当将浓度为0.2 mol/L的磷钼酸与质量浓度为15 g/L的葡萄糖混合溶液在120℃下连续加热24 h后,葡萄糖的有机物降解率达到43%,混合溶液连续进行5次加热-电解循环后,葡萄糖中有机物降解率可达到71%。将首次加热后的混合溶液在恒电压1 V下测试电流-电压曲线,初始电流密度和产氢量分别可达到191 mA/cm^2和175 mL。
Using glucose as reactant,a biomass electrolysis hydrogen production system is set up by means of a liquid catalyst fuel cell.The system’s performance in hydrogen production via glucose electrolysis is analyzed with phosphomolybdic acid as catalyst.The results show that the degradation rate of the organic matters in glucose can reach 43%after the mixed solution of phosphomolybdic acid(0.2 mol·L^-1)and glucose(15 g·L^-1)has been heated continuously for 24 h under 120℃.The degradation rate of organic matters in glucose can reach 71%after the mixed solution has been heated and electrolyzed for five consecutive cycles.The current-voltage curve of the first heated mixed solution is tested at a constant voltage of 1 V,and the initial current density and hydrogen production are 191 mA·cm-2 and 175 mL,respectively.
