▎ 摘  要

NOVELTY - A Bismuth-oxygen-iodine (BiOI)-graphene composite visible light catalyst comprises BiOI and graphene (1-3%). USE - Bismuth-oxygen-iodine (BiOI)-graphene composite visible light catalyst. ADVANTAGE - The catalyst has high visible light catalytic activity; and the preparation is environment-friendly and simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of the visible light catalyst comprising dissolving dispersing graphite oxide (0.007-0.022 g) to ethanol (15-25 ml), fully stirring for 1-2 hours to obtain suspension graphene oxide, adding glacial acetic acid at room temperature, taking 0.002 mol bismuth nitrate (3-10 ml), adding sodium iodide or potassium iodide and 10-50 ml deionized water while stirring, and obtaining suspension; and slowly dropping to solution for 2 hours, processing PTFE reaction kettle liner crystallization reaction at 120-150 degrees C for 6-12 hours, filtering, washing, and drying to catalyst.
