▎ 摘　　要

NOVELTY - A composite desulfurization photocatalyst comprises attapulgite inserted into graphene sheet to form staggered structure composite carrier, and nitrogen-containing compound as nitrogen source and doped with titanium dioxide to form nitrogen-doped titanium dioxide active component which is supported on composite carrier surface. USE - Composite desulfurization photocatalyst. ADVANTAGE - The composite desulfurization photocatalyst is environment-friendly, and has low raw material cost, improved light response range, and excellent photocatalytic property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite desulfurization photocatalyst comprising mixing oxidized graphene dispersion and titanium tetrachloride solution, ultrasonically dispersing for 0.5-5 hours, heating to 20-50 degrees C while stirring, dropping nitrogen-containing compound at speed of 3-4 mL/minute, adding attapulgite slurry, stirring for 1-5 hours, transferring to kettle, hydrothermally reacting to 160-220 degrees C for 8-24 hours, filtering, washing, and drying to 60-80 degrees C.
