摘要: 于阳离子隔膜的电解槽中,以MnO2/Mn2+电对作催化氧化的媒介,在超声波高频振荡下,电生成的MnO2颗粒以几十nm至几μm尺寸分散在溶液中.随后将甘油电化学氧化为甘油醛,该MnO2/Mn2+电对催化活性的选择性高,电流效率可达97.4%.

关键词: 超声波, 纳米MnO2, 有机电合成, 甘油醛

Abstract: Glyceraldehyde is prepared by using MnO2/ Mn2+as the media in a cationic membrane electrolytic cell.Under ultrasonic high-frequency oscillation,the electro-generated nanometer MnO2 dispersed in the solution with several tens nm till several micron.Then the MnO2 is used for selective oxidation of glycerine to glyceraldehydes.The catalyzing selectivity of MnO2/ Mn2+is high and the current efficiency may account to 97.4 %.

Key words: supersonic wave, nanometer MnO2, organic electro-chemistry, glyceraldehydes
