| 摘 要： | 用甘氨酸 硝酸盐燃烧合成法 ,制备LaxSr1 -xNiO3复合氧化物的陶瓷粉末。并以此为光电催化剂对不同水溶液染料进行光催化降解和光电催化降解实验。利用红外、紫外 可见光谱、循环伏安曲线研究LaxSr1 -xNiO3的催化性能。结果表明 :LaxSr1 -xNiO3(x =0 .1 5、0 .6、0 .7、0 .75、1 )复合氧化物都具有较强光催化特性 ,La0 .7Sr0 .3NiO3也具有光电催化降解特性 ;LaxSr1 -xNiO3的光催化活性高于LaNiO3,这与A位离子 (La3+ 、Sr2 + )的电子构型有关 ;Sr2 + 的加入可使LaNiO3的光催化活性有所提高 |

| Abstract: | Complex oxide powders of La_(x)Sr_(1-x)NiO_(3) prepared with glycine-nitrate process are used as a photo-electro-catalyst for degrading water-soluble dyes in the laboratory. The activity study of La_(x)Sr_(1-x)NiO_(3 )involves the use of a fluorescent Hg lamp as irradiation source and IR, UV-VIS and cyclic voltammeter. The results show the excellent photo-electro-catalytic activity of La_(x)Sr_(1-x)NiO_(3) (x = 0.15,0.6, 0.7, 0.75 and 1.0). It is concluded that La_(x)Sr_(1-x)NiO_(3) better activity of La_(x)Sr_(1-x)NiO_(3) than that of LaNiO_3 is attributed to the unique electronic structure of ion A (La~(3+), Sr~(2+)) and the adding of Sr~(2+). |
