Nano-sized WC was successfully synthesized on high surface area carbon by a novel carbothermal method wherein carbonization of mixture of hydroxypropyl cellulose (HPC) and K<SUB>2</SUB>WO<SUB>4</SUB> at 800 °C resulted in the simultaneous formation of carbon and WC nano-particles. Different with the common carbothermal method, porous carbon was obtained by pyrolysis of hydroxypropyl cellulose and the reducing gas of H<SUB>2</SUB> was not necessary.
