Efficient VOC removal over grape-like GdCoO3 perovskite prepared from the viscous mixture

Abstract

Grape-like GdCoO3 perovskite was synthesized through a straightforward one-step method. In this process, the combined raw materials were lightly dampened with a minute quantity of water to form a viscous state and subsequently subjected to a single-step calcination, resulting in the formation of the perovskite structure, all without the need for additional procedural steps. The characterization results indicated the presence of abundant reactive oxygen species distributed on the surface of GdCoO3. Most notably, the catalyst prepared in this manner exhibited remarkable catalytic activity for VOC oxidation.
