▎ 摘  要

NOVELTY - Preparing ultraviolet light-induced thiarized graphene catalytic material, comprises irradiating titanium dioxide with 15-40 W, preferably 20-35 W ultraviolet light source to excite 50-200 ml/minute, preferably 80-150 ml/minute carrier gas to obtain active intermediate, introducing graphene oxide, sulfur precursors and water, and performing low-temperature thermal annealing at 150-400 ℃, preferably 200-350 ℃ for 1-8 hours, preferably 2-6 hours to obtain final product. USE - The ultraviolet light-induced thiarized graphene catalytic material is useful in theoretical research; and in hybrid graphene materials. ADVANTAGE - The method: improves the ratio of edge-type thiarized graphene materials with high catalytic activity by adjusting the ultraviolet light induction time and reaction temperature, thus the hybridized graphene material has more excellent catalytic activity; can reduce the energy consumption and operation safety of the directional control of the catalytic material; and is helpful to deeply explore the catalytic mechanism of hybrid graphene materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for ultraviolet light-induced thiarized graphene catalytic material prepared by above method.
