Title:
COMPOSITE PHOTOCATALYST BASED ON THE NANO TITANIUM DIOXIDE AND CYCLIZED POLYACRYLONITRILE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/181913
Kind Code:
A1
Abstract:
A composite photocatalyst based on nano titanium dioxide and cyclized polyacrylonitrile, having a core-shell structure, wherein the core is titanium dioxide, the shell is cyclized polyacrylonitrile; the titanium dioxide is core-shell-structure titanium dioxide; the core-shell structure titanium dioxide comprises an outer shell and an inner core; a cavity is formed between the outer shell and the inner core; and the outer shell is prepared from self-assembled nano sheets. The composite photocatalyst integrates features of the core-shell-structure titanium dioxide and cyclized polyacrylonitrile into one to obtain better properties, including photocatalytic property, and the degradation rate of the composite photocatalyst to a pattern of contamination rhodamine B under visible light illuminating for 120 minutes can be up to 97%.
