▎ 摘　　要

NOVELTY - A silicon oxide (SiO)-graphite alkene photocatalyst comprises zinc oxide (ZnO); and graphene. The mass ratio of graphene and ZnO particle is 1:100-10:100. USE - SiO-graphite alkene photocatalyst useful for processing organic wastewater. ADVANTAGE - The photocatalyst has low cost, can be recycled, and has good photocatalytic effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing SiO-graphite alkene photocatalyst comprises: (A) taking soluble zinc salt and ammonium carbonate with ratio of 1:1-1:2 into de-ionized water and reacting for 1-2 hours, filtering, washing and drying at 900 degrees C for 2-2.5 hours; and (B) taking graphite oxide in water and mixed solution of absolute ethyl alcohol, dispersing for 0.5-1 hours, then adding zinc oxide, stirring and absorbing for 2-3 hours in reaction kettle at 120-180 degrees C under reaction tank for 3-8 hours, filtering, washing and drying to obtain ZnO nano-graphite alkene photocatalyst, where mass ratio of graphite and SiO is 1:100-10:100.
