Study of the electrocatalytic oxidation of hydrogen in alkaline solution by scanning electrochemical microscopy
摘要
利用扫描电化学显微镜的探头产生一基底收集工作模式,研究电位及溶液中OH浓度对Pt基底电催化活性的影响,以碓定碱性溶液中氢的电催化氧化反应的优化条件。
The effects of Pt substrate potential and concentration of OH-ions on the electrocatalytic oxidation of hydrogen in alkaline solution have been studied by the tip generation-substrate collection (TG-SC) mode of scanning electrochemical microscope (SECM). The parameter conditions for the electrocatalytic oxidation of hydrogen have been optimized.
