NOVELTY - A nano-carbon/titanium dioxide composite material is prepared by hydrolyzing tetrabutyl titanate and nano-carbon and pyrolyzing at high temperature. USE - Nano-carbon/titanium dioxide composite material. ADVANTAGE - The preparation of nano-carbon/titanium dioxide composite material is realized through simple hydrolysis and subsequent high-temperature pyrolysis, with good repeatability. The composite has high photocatalytic activity and good electrochemical activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the nano-carbon/ titanium dioxide composite material, which involves adding tetrabutyl titanate dropwise to nano-carbon, mixing well and stirring, dripping water in the mixture during stirring, placing in a muffle furnace for heat treatment after drying and grinding the mixture, and cooling to room temperature after heat treatment.
