摘要：NOVELTY - A mesocellular foam (MCF)/titanium dioxide load type photocatalyst preparing method involves subjecting weighed amount of triblock polymer polyoxyethylene-polyoxypropylenepolyoxyethylene as a template, preparing mesoporous MCF sieve, hydrothermally reacting the sieves with titanium sulfate as titanium source. The obtained hydrothermal product is washed and dried. Ammonium fluoride is added into the mixture and uniformly ground. The obtained product is sintered in air or vacuum under varying temperature to obtain fluorine-doped MCF/titanium dioxide load type photocatalyst. USE - Method for preparing MCF/titanium dioxide load type photocatalyst. ADVANTAGE - The method enables preparing load type photocatalyst with strong visible light absorption ability and high photocatalytic activity and hydrophobicity. The method is simple and economical.
