As a hydrogen evolution catalyst, carbon-coated tungsten oxide greatly improves the hydrogen evolution performance of electrolytic water of tungsten oxide in acid media, and shows good electrochemical stability. Wherein, the improvement of the catalytic performance of this kind of catalyst is mainly controlled by Gibbs free energy of hydrogen adsorption of tungsten oxide through carbon coating. Well, what is the mechanism for the enhancement of the electrochemical hydrogen evolution performance of carbon-coated tungsten oxide?

As a well-known electrochromic material, the studies on the preparation of tungsten oxide film are getting more and more important. The researchers have prepared tungsten oxide films by sol-gel and spin-coating methods using PTA as the precursor sol.

Tungsten oxide nanoparticles are widely applied to smart windows in the form of an electrochromic film as tungsten oxide (WO3) is a feasible electrochromic material that can be of benefit in practical applications due to its rather highly optical reversible color change induced by an electrochemical process. Well, do you know how to prepare electrochromic film of tungsten oxide nanoparticles?

Nano tungsten trioxide is well-known as an important electrochromic material for producing electrochromic glass. And the fabricated electrochromic glass is also called smart glass with the performance of adjusting the heat radiation and UV radiation of sunlight. Therefore, the electrochromic glass of nano tungsten trioxide is promising in the application of newly-built buildings, for reducing room temperature, saving energy and improving human comfort.
