NOVELTY - A mercury-free and precious metal-free catalyst comprises carbon, graphite, graphene or carbon nano tube as carbon carrier, and a reactive metal loaded on the carbon carrier. The active carbon is prepared by taking a nitrogenous high molecular material e.g. polyacrylamide, polyaniline and melamine, as precursor material as carrier and subjecting to in-situ polymerization. The metal is chosen from titanium, zirconium, iron, cobalt, nickel, copper, zinc, bismuth, tin, silver, antimony and lead, or their complex. USE - Mercury-free and precious metal-free catalyst used for preparing chloroethylene. ADVANTAGE - The catalyst is prepared economically.
