99.99% High Purity Gold Nanopowder Au Nanoparticles for Coating
Description of nano gold powder:
Application of nano gold powder as coating:
Professors at a university in Australia have discovered that tiny particles of gold can decompose organic pollutants under the action of sunlight, purifying the air and can be used to make a new generation of photocatalysts: nano-gold powder coatings.
For the past 20 years, scientists have been convinced that gold can only catalyze at temperatures between 100 degrees Celsius and 200 degrees Celsius. In fact, if gold is as small as nano-granules, it will become very active under sunlight, which can decompose organic pollutants.
The surface electromagnetic field of an object coated with gold nanoparticles can be enhanced by hundreds of times under sunlight, thereby breaking down "volatile organic compounds." Such contaminants in the air often come from new furniture, carpets and finishing materials, which not only emit odors, but also endanger human health. The new discovery means that in the future, people can paint art on the windows of the living room with nano-gold powder paint, which can not only remove the formaldehyde odor left by the interior decoration, but also purify the indoor air and remove the organic pollutants on the wall and the ground. At the same time, it also beautified the living room.
When it comes to the word "gold", people think that the cost will be very high. In fact, this coating with gold nanoparticles is not expensive, because gold nanoparticles only account for 3% of the entire coating.
