用SNIFTIRS和循环伏安法研究次亚磷酸根离子在多晶铂电极上的电氧化机理 .分析了0 .5mol/LH2 SO4 + 0 .1mol/LNaH2 PO2 溶液中原位红外反射谱图与Pt电极电位的关系 ,发现次亚磷酸根离子在Pt上发生解离吸附 ,其氧化产物是H3 PO4 ,不同于在Ni上的氧化产物H2 PO- 3 ,据此提出了酸性溶液中次亚磷酸根离子在Pt上氧化机理的新看法
The electrooxidation mechanism of hypophosphite ion on polycrystalline Pt electrode was investigated by SNIFTIRS and cyclic voltammetry.The in-situ infrared reflectance spectra of 0.5 mol / LH 2 SO 4 +0.1 mol / L Na 2 P 2 O solution and the Pt electrode potential It was found that the hypophosphite ions were dissociatively adsorbed on Pt. The oxidation product was H3 PO4, which was different from the H2 PO-3 oxidation product on Ni. Therefore, it was proposed that hypophosphite ions in acidic solution New Perspectives on the Oxidation Mechanism of Pt
