▎ 摘 要
NOVELTY - Improving photocatalytic activity of bismuth ferrite-graphene oxide composite material comprises (i) placing photocatalytic reactant and bismuth ferrite-oxide graphene composite material in transparent container, then placing transparent container in ultrasonic machine, where bottom of ultrasound machine via flowing water, and (ii) open the light source for photocatalytic reaction, during the reaction, turning ultrasonic machine on to produce ultrasonic vibration. USE - The method is useful for improving photocatalytic activity of bismuth ferrite-graphene oxide composite material (claimed).
