Photocatalytic TiO2/WO3 by Spray Drying with Energy Storage Ability from Ammonium Paratungstate

Image of proposed mechanism

Titanium dioxide (TiO2) photocatalysis using sunlight as an irradiation source is a feasible technique to degrade pollutants in air. Although TiO2 possesses enticing properties such as chemical stability, strong oxidizing power, photo-resistance, availability, and low cost, its photocatalytic activity remains insufficient for large-scale applications.

Gas–Solid Synthesis of Tungsten Carbide from Ammonium Paratungstate at Low Temperature

Particle size distribution curve of WC obtained from APT

Tungsten carbide (WC) has been widely applied as integral composition of hardmetal, or cemented carbide. Cemented carbides are composite materials consisting of a hard phase (WC) and a metal, usually Co, which binds the WC grains. The composition of the material (amount of Co) mostly influences their mechanical properties. The greater the Co content the tougher and softer the material is. Hardmetal is used for cutting, drilling and wear resistant pieces.
