Photochromism of Titanium Oxide Gels Prepared by the Salt-Catalytic Sol-Gel Process

摘要

Photochromism for the monolithic gel of titanium oxide prepared by the catalytic sol-gel process was observed. When hydrazine monohydrochloride was used as a catalyst, an intense blue color development was observed with the formation of Ti~(3+) on the irradiation of UV light (
