碳载硫化铑催化剂在酸性体系中的氢氧化性能
Hydrogen oxidation performance of carbon-supported rhodium sulfide catalyst in acidic system
摘要
Abstract
To address the issue of poor stability of traditional commercial Pt/C electrocatalysts in acidic electrolytes,espe-cially in hydrochloric acid,a stable and efficient hydrogen oxidation reaction electrocatalyst,namely RhxSy/C nanocatalyst supported on carbon,was prepared using a method of condensation reflux followed by low-tempera-ture calcination.The influence of calcination temperature on the catalytic performance of the electrocatalyst was investigated through physical characterization and electrochemical testing in 1 mol/L HCl.The results indicate that different calcination temperatures lead to different crystal phases in the RhxSy/C nanoparticles,thereby af-fecting the overall catalytic performance of the catalyst.The RhxSy/C catalyst prepared at a calcination tempera-ture of 350 ℃ possesses both certain hydrogen oxidation activity and good stability,maintaining 87.1%of its catalytic activity after 1 000 cycles of accelerated aging stability tests.关键词
