近年来随着太阳能光化学研究的进展,Schrauzer和Outh首先发现,在湿的TiO_2半导体粉末上,用光催化还原氮的方法。Fujishima等人用TiO_2、ZnO和SiC粉末在氮气的饱和水溶液里照射的方法合成了氨,但所得氨的产率很低。Miyama等人用掺入铂黑的TiO_2,ZnO_2,SrTiO_3,CdS,GaP半导体粉末和SiC的方法提高了氨的产率。用GaP-Pt时氨的 In recent years, with the progress of solar photochemistry, Schrauzer and Outh first found that wet TiO 2 semiconductor powder, photocatalytic reduction of nitrogen. Fujishima et al. Synthesized ammonia by irradiating TiO 2, ZnO, and SiC powders in a saturated aqueous solution of nitrogen, but the yield of obtained ammonia was very low. Miyama et al. Have increased the yield of ammonia with the incorporation of platinum black in TiO 2, ZnO 2, SrTiO 3, CdS, GaP semiconductor powders and SiC. Ammonia with GaP-Pt
