Insights into the Low-temperature Synthesis of LaCoO3 Derived from Co(CH3COO)2 Via Electrospinning for Catalytic Propane Oxidation

Summary of main observation and conclusion A series of electrospun LaCoO3 perovskites derived from CoX2 (X =CH3COO-,NO3-) were prepared and investigated for total propane oxidation.It is shown that pure rhombohedral perovskite LaCoO3 from Co(CH3COO)2 can be obtained at a relatively low temperature,400 ℃,benefitting from the complexation effect of CH3COO-.On the other hand,CH3COO-can accelerate the complete decomposition of polymer.The low-temperature process can protect LaCoO3 nanoparticles from growing up.
