制备了一系列La 1 − xSrxFeO 3（x = 0.0-1.0）氧化物，研究了钙钛矿型复合氧化物LaFeO 3（ABO 3型钙钛矿）中A位取代对芳香硝基化合物以异丙醇为氢供体、KOH为促进剂的催化转移氢化反应的影响.用于制备钙钛矿的常规方法需要在高温下长时间的传导加热。我们采用微波辐射法快速合成了La 1 − xSrxFeO 3（x = 0.0，0.2，1.0）钙钛矿化合物，并测试了其对硝基苯还原反应的催化活性。动力学研究也进行了硝基苯还原。
A series of La1−xSrxFeO3(x = 0.0–1.0) oxides were prepared to study the influence of A-site substitution in perovskite-type mixed oxides LaFeO3(ABO3-type perovskites) on the catalytic transfer hydrogenation of aromatic nitro compounds using propan-2-ol as hydrogen donor and KOH as promoter. The conventional method for the preparation of perovskites requires conductive heating for extended periods at elevated temperatures. We have used microwave irradiation method for the rapid synthesis of La1−xSrxFeO3(x = 0.0, 0.2, 1.0) perovskites and the catalytic activity of these samples has been tested for the reduction of nitrobenzene. Kinetic studies have also been performed for nitrobenzene reduction.
