新型光催化剂掺锶钴酸镧的研究

Study on the new photocatalyst of La_( 1- x) Sr_x CoO_( 3-δ)

以溶胶—凝胶法合成了催化剂 ,实验了光催化剂中Sr掺杂量、光照时间和催化剂用量对染料酸性铬蓝脱色率的影响 ,结果表明 :La1 -xSrxCoO3

A new photocatalyst of perovskite structure with oxygen deficiencies, La 1- x Sr x CoO 3-δ were prepared by sol gel process. The relations of decolorizing efficiency with a dye solution to the doped mol ratio of Sr 2+ , to the irradiation time of sun light, and to the amount of the photocatalyst were investigated. The results show La 1- x Sr x CoO 3-δ is a more activated photocatalyst than TiO 2.
