Preparation methods and uses of doped VIB group metal oxide nanoparticles or dispersions thereof
The present invention is related to a method for preparing VIB Group metal oxide particles or dispersions, wherein the VIB Group metal is tungsten or molybdenum. The methods include: 1) providing precursors of VIB Group metal oxide, reductants and supercritical fluids. 2) said VIB Group metal oxide particles, or dispersions are obtained by the reaction between said metal oxide precursors, and reductants are under supercritical state in said supercritical fluids. Especially, said VIB Group metal oxide can be tungsten bronze, molybdenum bronze, or tungsten and molybdenum bronze which can be present by the formula AxByMOz. Wherein, A represents element exists in the form of dopant cation; and B represents element exists in the form of dopant anion; O represents oxygen; 0≤x≤1, 0≤y≤1, 0<x+y≤1, and 2≤z≤3. The said VIB Group metal oxide particles and dispersions can be applied to the glasses of houses, buildings, automobiles, ships etc, with high transparency and NIR and UV lights shielding properties, by which the control of sunlight and heat radiation can be achieved.
