Tungsten oxide nanopowder may be applied for the preparation of heat insulation coating, mainly reflecting its photochromic properties. It means that tungsten oxide plays a high thermal insulation role in the field of buildings and vehicles. Nano grain size tungsten oxide may also be used for the photolysis of water to produce hydrogen, and for the treatment of organic pollutants, mainly reflecting its photocatalytic performance. It means that tungsten oxide plays a role in photocatalysis and degradation, respectively. However, the…
