▎ 摘　　要

NOVELTY - Aerobic/anaerobic dual-purpose visible photocatalyst i.e. zirconium-metal-organic frameworks/reduced graphene oxide/silver phosphate visible light catalyst (I), is new. In visible light catalyst zirconium-metal-organic frameworks are wrapped by sheet-like reduced graphene oxide and silver phosphate nanoparticles are dispersed on the surface of zirconium-metal-organic frameworks/reduced graphene oxide to form a Z-type heterojunction; the conduction band edge potential of the visible photocatalyst is lower than the direct generation potential of O2- and valence band edge potential is higher than the direct generation potential of OH. USE - The visible photocatalyst is useful for: degradation of organic pollutant; and inactivation of bacteria (claimed). ADVANTAGE - The method: has simple operation, mild reaction conditions, short synthesis period and good repeatability; is suitable for large-scale mass production compared to other existing methods. The visible photocatalyst: has significant visible light photocatalytic activity; exhibits high photocatalytic efficiency in both aerobic and anaerobic states; and shows broad range of pollutant degradation and sterilization in the water environment. DETAILED DESCRIPTION - Aerobic/anaerobic dual-purpose visible photocatalyst i.e. zirconium-metal-organic frameworks/reduced graphene oxide/silver phosphate visible light catalyst of formula (I) (MOFs/rGO/AgPO4), is new. In visible light catalyst zirconium-metal-organic frameworks are wrapped by sheet-like reduced graphene oxide and silver phosphate nanoparticles are dispersed on the surface of zirconium-metal-organic frameworks/reduced graphene oxide to form a Z-type heterojunction; the conduction band edge potential of the visible photocatalyst is lower than the direct generation potential of O2- and valence band edge potential is higher than the direct generation potential of OH. An INDEPENDENT CLAIM is also included for preparation of (I).
