▎ 摘　　要

NOVELTY - Iron(II,III) oxide-graphitic carbon nitride/reduced graphene oxide composite photocatalyst is claimed. The photocatalyst is obtained by interposing chip reduced graphene oxide between the layers of the layer graphitic carbon nitride, and supporting nano wires formed of iron(II,III) oxide particles on the upper surfaces of graphitic carbon nitride and reduced graphene oxide. USE - Used as iron(II,III) oxide-graphitic carbon nitride/reduced graphene oxide composite photocatalyst. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing iron(II,III) oxide-graphitic carbon nitride/reduced graphene oxide composite photocatalyst comprising (i) preparing graphitic carbon nitride powder, (ii) dispersing graphitic carbon nitride powder in ethylene glycol, ultrasonicating, magnetically stirring under water bath, adding iron nitrate nonahydrate, sodium acetate, polyethylene glycol 4000 and polyvinylpyrrolidone, ultrasonically agitating, adding redox graphene until the raw materials are uniformly dispersed or dissolved, where dosage ratio of graphitic carbon nitride, glycol, iron nitrate nonahydrate, sodium acetate, polyethylene glycol 4000, polyvinylpyrrolidone and redox graphene is 0.1-1 g:10-60 ml:0.02-0.4 g:0.02-0.4 g:0.003-0.04 g:0.0005-0.008 g:0.005-0.015 g, (iii) adding obtained dispersion into a hydrothermal kettle and reacting at 180-220 degrees C for 10-15 hours, and (iv) collecting solid product, cooling to room temperature, washing and then drying to obtain final product.
