▎ 摘　　要

NOVELTY - Preparing bismuth tungstate/reduced graphene oxide/bismuth ferrite composite photocatalyst comprises (i) dissolving sodium tungstate and bismuth nitrate in deionized water to obtain clear solution, then transferring into high-pressure reaction kettle, and reacting at 150-220 degrees C for 20-24 hours to obtain bismuth tungstate, (ii) dissolving graphene oxide in deionized water, adding ascorbic acid, and sonicating for 10-20 minutes to obtain reduced graphene oxide dispersion, and (iii) dissolving bismuth tungstate in deionized water, adding ferric nitrate, adjusting the pH value to 10-11, adding the reduced graphene oxide dispersion obtained in step (ii), and stirring, transferring into high-pressure reactor and reacting at 180-220 degrees C for 6-8 hours to obtain composite photo-catalyst. USE - The bismuth tungstate/reduced graphene oxide/bismuth ferrite composite photo-catalyst is useful in degrading organic dyes and/or antibiotics. ADVANTAGE - The method: is simple, utilizes less organic solvent and has low production cost and is environmentally friendly. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) bismuth tungstate/reduced graphene oxide/bismuth ferrite composite photocatalyst obtained by above method; and (2) use of bismuth tungstate/reduced graphene oxide/bismuth ferrite composite photocatalyst in degrading organic dyes and/or antibiotics.
