日本化学技术研究所使用半导体催化剂(TiO_2)开发成功一种完全分解有机磷化物的技术。有机磷化物广泛用作农药和表面活性剂,但存在环境污染问题。使用半导体光催化剂之一的TiO_2,确立了将磷酸三甲酯、膦酸三甲酯和二硫代磷酸二甲酯进行光解的技术。该项技术作为处理有机磷化物的方法而引人注目。当以粒径为1.3微米的TiO_2作催化剂,在阳光下反应时(在三甲基磷酸溶液250毫升中混合TiO_21克 Japan Institute of Chemical Technology using semiconductor catalyst (TiO 2) developed a complete decomposition of the organic phosphide technology. Organophosphorus compounds are widely used as pesticides and surfactants, but there are environmental problems. The use of TiO 2, one of the semiconductor photocatalysts, established a technique for photolysis of trimethyl phosphate, trimethyl phosphonate and dimethyl dithiophosphate. This technique is attracting attention as a method of treating organophosphorus compounds. When TiO 2 with a particle size of 1.3 μm was used as a catalyst, the reaction was performed in the sunlight (mixed TiO 2 21 g in 250 ml of trimethylphosphoric acid solution
