Description

technical field [0001] The invention relates to the field of building materials, in particular to a photocatalytic coating. Background technique [0002] Since 1972, Professor Benta of the University of Tokyo and Professor Tengshima Akira, who was a doctoral student at the time, accidentally discovered that irradiating titanium dioxide electrodes with light can split water into hydrogen and oxygen, which is called the "Hondo-Tengshima effect". Since the phenomenon of nano-titanium dioxide, the photocatalytic properties of nano-titanium dioxide have been confirmed by many researches and applications. 10g of nano-titanium oxide photocatalyst is evenly painted on four glass plates of 500mm×500mm, and after natural drying, it is placed in the inner warehouse of 600mm× 600mm×600mm environmental climate box. Adjust the temperature in the environmental climate chamber to keep it at (23±2)°C, adjust the humidity in the cabin to keep it at (50±5)%, and the light source is a 40W fluo...
