文摘

GQD/BiVO4 composites could significantly enhance the solar-driven photocatalytic activities for CBZ. Multi-factors influencing degradation process were investigated. Potential transformation products during the degradation process were tentatively identified. Hydroxylation or cleavage of amide group on the heterocycle may be the main initial photocatalytic degradation channels.
