多相催化剂用于高级烯烃分子氧选择性氧化的研究进展

Research progress of heterogeneous catalyst in molecular oxygen selective oxidation of advanced olefin

针对以高级烯烃作为底物进行的分子氧氧化反应,所用多相催化剂按其结构和组成不同,可分为金属-有机配体复合催化剂、金属氧化物催化剂、无机分子筛催化剂、多氧金属盐类催化剂和负载型催化剂等。综述了各类催化剂用于高级烯烃分子氧选择性氧化的研究进展,并比较了各自的优缺点,指出负载型催化剂在一定程度上克服了其他几类催化剂存在的催化氧化选择性差、重复利用率低、稳定性差等缺点,有望在无溶剂的条件下获得较佳的转化率及选择性,是未来高级烯烃绿色氧化催化剂的重要研究方向。

The heterogeneous catalysts for the molecular oxygen selective oxidation of advanced olefin as the substrate were classified according to their structure and composition as metal-organic complex composite catalyst, metal oxide catalyst, inorganic molecular sieve catalyst, polyoxometalate catalyst and supported catalyst. The research progress of heterogeneous catalysts in molecular oxygen selective oxidation of advanced olefin was reviewed. And their advantages and disadvantages were compared. It was pointed out that the research trend of green catalysts for advanced olefin oxidation should be dominantly focused on supported catalyst because it was superior to the other catalysts having the disadvantages of poor selectivity, low reusing rate and poor stability and was expected to acquire better conversion rate and selectivity in solvent-free condition.
