铂和其元素周期表中相邻元素作为催化剂被广泛应用于化学合成、石油化工、聚合和环境保护等化学工业领域.但是铂族金属或Ⅷ族过渡金属,特别是铂、钯、铑、铱、钌等稀有贵金属,其储量逐年减少,需求量却逐年增加.研究表明,碳化钼在很大范围内具有与铂族金属相同的催化性能.因此, Platinum and its adjacent elements in the Periodic Table of Elements are widely used as chemical catalysts in the chemical industry such as chemical synthesis, petrochemicals, polymerization and environmental protection etc. However, platinum group metals or Group VIII transition metals, especially platinum, palladium, rhodium, iridium , Ruthenium and other rare precious metals, the reserves decrease year by year, but the demand has increased year by year.Research shows that the molybdenum carbide has the same catalytic performance as the platinum group metal in a wide range.Therefore,
