Abstract
A preparation method of a titanium-dioxide-based double-layer hollow material includes the following steps: (1) using polystyrene nanospheres with particle size of 180 nm as a template, tetrabutyl titanate as a precursor, to prepare hollow titanium dioxide by calcining; (2) subjecting said hollow titanium dioxide to carboxylation modification to prepare carboxylated titanium dioxide; and (3) dispersing said carboxylated titanium dioxide in ethanol, using chromic nitrate nonahydrate as an assembly agent and trimesic acid as a crosslinking agent to carry out layer-by-layer self-assembly so as to prepare the titanium-dioxide-based double-layer hollow material.
