摘　　要：提出了一种新型制备钙钛矿的方法-PVA聚合物辅助法,并成功制备了SrCoO3电催化剂.与其他的合成方法相比,该方法合成时间更短,步骤简洁,便于规模化生产.与传统PEI聚合物辅助法相比,PVA更环保,煅烧过程中无有毒有害气体产生.对SrCoO3样品进行了XRD和BET表征,并在0.1 mol/L KOH溶液中测量了其OER性能.结果表明,该方法适合大规模合成高性能钙钛矿材料.A new PVA polymer assisted method for preparing perovskite was firstly proposed.Compared with other synthesis methods,it has the advantages of shorter synthesis time,simple steps,and convenient large-scale production.Compared with the PEI polymer-assisted method,PVA-assisted method is more environmentally friendly without poisonous gas during calcination.The SrCoO3 samples were characterized by XRD and BET,and the OER performance was measured in 0.1 mol/L KOH solution.The results show that this method is suitable for large-scale synthesis of high performance powders.
