Formation of pure-phase W2C nanoparticles through carbothermal reduction in the presence of Pd(0) nanoparticles

The direct synthesis from elements of tungsten semicarbide, W2C, taking place in a narrow concentration range and at high temperatures, is unsuited for some applications requiring small particle sizes. We report an efficient synthesis method for obtaining pure phase W2C at low temperatures (
