▎ 摘  要

NOVELTY - A photocatalyst comprises titanium dioxide doped with nano material selected from graphene and cabon nanotube that have zeolitic imidazolate framework (ZIF-8). USE - The photocatalyst is used for sewage treatment. ADVANTAGE - The photocatalyst has excellent catalytic performance by graphene and carbon nano tubes, and excellent adsorption performance by ZIF-8. The photocatalyst has excellent sewage treatment efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of nanomaterial-doped titanium dioxide photocatalyst. The method involves: 1) adding hydrochloric acid (HCl) into distilled water, adding tetrabutyl titanate (TBOT) and stirring uniformly to form titanium dioxide (TiO2) precursor solution, with volume ratio of TBOT and HCl 1: 30; 2) adding a nano material into the precursor solution and preparing the photocatalyst by a hydrothermal method, with mass volume ratio of nano material to TBOT 1:2 g/ml. The nano material used is graphene or carbon nano tube.
