摘要 采用原位拉曼光谱技术研究方波电位循环氧化还原 (ORC)过程中产生的铂氧化物的还原过程 ,其中过氧化物和超氧化物消失的电位在 0 2V左右 ,晶格氧化物和氧化铂则分别消失在 0V和 -0 2 5V左右。 The electrochemical reduction process of four kinds of platinum oxides was studied by in-situ confocal Raman microscopy The effect of the nanometer particles formed at different reduction potentials to methanol oxidation was also investigated
