Patent Title: Method for preparing surface molecular imprinting composite photocatalyst
Publication date: 2012
Publication number: CN102600904

Abstract: The invention discloses a method for preparing a surface molecularly imprinted composite photocatalyst, and belongs to the technical field of the preparation of ecomaterials. According to the invention, a TiO2/floating bead photocatalyst is prepared through a sol-gel technology and o-phenylenediamine modified modification is carried out on the TiO2/floating bead photocatalyst and then the surface of the TiO2/floating bead photocatalyst is modified through a surface molecular imprinting technology, so that the surface molecular imprinting POPD (poly(o-phenylenediamine))/TiO2/floating bead composite photocatalyst with a high catalytic activity is prepared. The invention has the technical advantages that the utilization rate of light sources is effectively improved through the suspension characteristic of the photocatalyst; linkage sites can be better provided for the immobilization of surface molecularly imprinted polymers through the POPD modified modification; and the problem that common photocatalysts cannot selectively degrade targeted pollutants can be well solved through the introduce of the surface molecularly imprinting technology.
