  We report that the cathodic preconcentration of electron-insulating As(0)on Au and Pt electrodes can be enhanced by chemical reduction of As(Ⅲ)and As(Ⅴ)by electrogenerated H2,as studied by cyclic voltammetry.

亚胺作为药物和精细化学品等领域重要的合成中间体,引起了人们广泛的合成兴趣.半导体光催化着眼于利用空气中的分子氧将胺氧化为亚胺并且已经取得了较好效果.然而在制药工业中,氧化反应由于存在原子利用率低、反应选择性差等问题而很少被使用.因而理解光催化高选择性的机理就有了重要意义.
