摘要：
An efficient and technologically simple technique has been proposed for the immobilization of nanocrystalline titanium dioxide on a quartz glass. It consists in deposition of the powder from its aqueous suspension with the addition of acetylacetone. The technique makes it possible to keep the phase composition and size of the initial titanium dioxide nanoparticles, the coating uniformity, and its stability under hydromechanical treatment. The photocatalytic efficiency of the coating in the reaction of the decomposition of a methyl orange dye in an aqueous solution in a flow reactor is shown.
