Development of self-cleaning glass

The research on self-cleaning glass in China began in the late 1990s. During the period of 1999, Wuhan University of Technology and Dalian Institute of Light Industry published a paper on coating TiO2 _ 2 thin film on glass surface by sol-gel method. In 2000, the author and other collaborators published the research results of improving the photocatalytic performance of TiO2 _ 2 film on glass surface by CeLa doping at the National Catalytic Conference and China chinese journal of catalysis, and obtained the invention patent in cooperation with Qinhuangdao Hua Yao Glass Group Company. Later, the research on the preparation of clean glass by CVD was carried out. In 2005, Qinhuangdao Hua Yao Glass Co., Ltd. has produced self-cleaning glass by CVD online coating and put it on the market, with an annual design and production capacity of more than 4 million square meters.
