▎ 摘　　要

NOVELTY - A full solar spectrum response cobalt(II,III) oxide/reduced graphene oxide (Co3O4/rGO) composite catalyst is prepared by placing cobalt precursor, oxalic acid, sodium hydroxide, graphene oxide and hydrazine hydrate in reaction kettle, hydrothermal reacting, centrifugally washing, vacuum drying and calcining in tubular furnace. The cobalt precursor is cobalt chloride. USE - The method is used for preparing full solar spectrum response cobalt(II,III) oxide/reduced graphene oxide composite catalyst for atmosphere pollution control field (claimed). ADVANTAGE - The product can make full use of entire solar spectrum energy and effectively convert solar energy into thermal energy, has high catalytic efficiency and low energy consumption in catalytic process, expands absorption range of solar light, achieves efficient photothermal catalytic degradation of volatile organic compounds without additional heating, and realizes organic combination of photocatalysis and thermal catalysis.
