Abstract
The invention discloses a production method of an air purification catalyst which is a nitrogen-atom-doped nano titanium dioxide photocatalyst. The catalyst is characterized by comprising the following components by weight percent: 2%-20% of nitrogen-atom-doped nano titanium dioxide, 0.5%-5%of a dispersant, 0.5%-5% of a bonder and the balance of solvent water; nitrogen-atom-doped nano titanium dioxide is obtained by nitriding titanium dioxide in a microwave heating manner; the microwave heating power is 800-3000W, the temperature is 400-1000 DEG C, and the heat preservation time is 5-30 minutes. The catalyst can be used for quickly, efficiently and lastingly purifying air to radically remove harmful gas such as formaldehyde, benzene, methylbenzene, dimethylbenzene, ammonia and TVOC (total volatile organic compound) and inhibit and kill bacteria. The production process is simple, the production cost is low, and the catalyst is nontoxic, tasteless, safe and environment-friendly.

Background technology
From the seventies, the Japan Teng clear professor in island finds TiO first
2photocatalysis performance since, TiO
2photocatalysis technology has obtained development fast at aspects such as solar cell hydrogen manufacturing, environmental pollution improvement and sterilization, sterilizations, particularly in recent years, along with becoming increasingly conspicuous of energy and environment problem in world wide, the research of photocatalysis technology more and more comes into one's own.
But TiO
2semiconductor energy gap be 3.2 electron volts, this has just determined TiO
2absorbing light can only be at ultraviolet region, and indoor illumination medium ultraviolet light very a little less than, by general TiO
2being applied to indoor air purification has little effect.In order to make TiO
2photocatalyst produces effectively and absorbs at visible region, and we are by carrying out modification to Nano titanium dioxide microwave doping nitrogen-atoms.
