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 °C, 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. As a result, Co(CH3COO)2‐derived catalysts exhibit better propane oxidation activity than the ones suffered the same thermal treatment by using Co(NO3)2. XPS and H2‐TPR analysis provide that there is subtle change in Co3+/Co2+ on bulk/surface of Co(CH3COO)2‐derived catalysts prepared at different temperatures, giving rise to similar propane oxidation activities. Moreover, the result of cyclic stability test over 400 °C obtained catalyst shows little deactivation, demonstrating a good thermal stability. Our study can provide a feasible route for energy‐saving synthesis of LaCoO3 catalyst applied in the catalytic oxidation of volatile organic compounds (VOCs). [ABSTRACT FROM AUTHOR]

[Display omitted] • Co species are active sites for C 3 H 8 oxidation despite Pt loading. • Coaxial electrospinning anchors Pt on both surface and bulk phase. • Coaxial electrospun Pt/LaCoO 3 gives the best C 3 H 8 oxidation activity. • Surface Pt favors Co3+ → Co2+ while bulk Pt accelerates Co2+ → Co0+. • Redox property and lattice oxygen mobility are crucial. The effect of location sites of platinum (Pt) nanoparticles on LaCoO 3 support for complete catalytic oxidation of propane (C 3 H 8) was investigated. Pt nanoparticles were anchored on the surface, bulk and surface/bulk of LaCoO 3 by using three different loading methods: incipient-wetness impregnation, single-needle electrospinning and coaxial electrospinning, respectively, followed by a simple 300 °C H 2 reduction process. The obtained catalysts were systematically characterized. It turns out that one step synthesis of coaxial electrospun Pt/LaCoO 3 nanotubes with both surface and bulk Pt species exhibits a relatively more efficient catalytic activity, where surface Pt favors the reduction of Co3+ to Co2+ and bulk Pt accelerates that of Co2+ to Co0. Meanwhile, Co species are active sites for C 3 H 8 oxidation despite Pt loading, but the enhanced redox property and oxygen mobility upon Pt loading are crucial for the Mars-van Krevelen mechanism obeyed total C 3 H 8 oxidation. Additionally, good thermal stability is found over coaxial electrospun Pt/LaCoO 3 , removing propane at a temperature of 450 °C over 48 h without a significant decrease in propane conversion. The addition of water vapor has a little inhibition effect on the catalytic activity under the reaction condition. Such route of Pt anchoring will provide an effective means for designing highly efficient perovskite based catalysts with low precious loadings for total oxidation reaction. [ABSTRACT FROM AUTHOR]
