▎ 摘　　要

NOVELTY - A nano zinc ferrite-graphene compound photocatalyst is formed by compounding nano zinc ferrite with graphene at a mass ratio of 1:2-6. USE - A nano zinc ferrite-graphene compound photocatalyst for use in sewage treatment. ADVANTAGE - The photocatalyst has visible light response, and has uniform particle size and uniform dispersion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the photocatalyst comprising mixing graphite oxide and ethyl alcohol; subjecting to ultrasonic dispersion; mixing ferric nitrate, zinc nitrate, and ethyl alcohol; stirring for 30-60 minutes; adding dispersed solution; subjecting to hydrothermal reaction at 160-200 degrees C for 12-24 hours; centrifuging; washing with deionized water; and drying. DESCRIPTION OF DRAWING(S) - The drawing is a schematic view of a method of preparing a photocatalyst. Drawing includes non-English language text.
