Abstract
The invention provides a method for preparing photocatalyst spray capable of effectively using visible light and stabilizing the long-term purifying effect, and a spraying process of the spray. The photocatalyst spray consists of 1-2 percent of modified nano-TiO2 photocatalyst, 0.5-1 percent of anti-bacterial agent, 30-35 percent of plant essence, 1-2 percent of chelating agent and 60-65 percent of water, wherein the modified nano-TiO2 photocatalyst is prepared by modifying doped precious metals. According to the photocatalyst spray, the photocatalytic performance continually plays a role in purifying under the condition of dark light source and even no illumination in a certain period of time due to doping of an appropriate quantity of noble metals. The construction process comprises the following steps: preserving noble wearable articles, moving to leave a vacant place, cleaning, shielding for protecting, high-temperature fumigation, spraying and ventilation. The adopted spraying process is suitable for spraying the photocatalyst spray onto the surfaces of different indoor articles, so that the problems of waste of the spray, damages to the articles and the like are solved.
