摘要 利用离子熔盐法合成了MTiO3型复合氧化物,合成温度范围为700~1100℃,反应时间为4h或6h,熔剂为Na2CO3-KCl混合物.讨论了合成条件对CaTiO3光催化活性的影响. Finely diapered powders of calcium,strontium and bariunl titanates have been prepared by precipitation in melten salts.The synthesis has been performed in a temperature range from 700 to 1000℃.with reaction time up to 8h.Na2CO3-KCl mixture has been used as the reaction medium.The effect of tempcrature and reaction time on the photoeatalytic activity is discussed.
