Subnanometric PtIn clusters have been synthesized within pure silica MFI zeolites by post-synthetic incorporation of In to Pt@K-MFI. The optimized PtIn@K-MFI catalyst outcompetes state-of-the-art PtSn formulations in ethane and propane dehydrogenations, avoiding the need of large excess of Pt promoters and harsh reductive conditions.
通过将铟后合成掺入Pt@K-MFI中，在纯硅MFI沸石中合成了亚纳米级的PtIn团簇。优化后的PtIn@K-MFI催化剂在乙烷和丙烷脱氢反应中优于现有的PtSn配方，避免了大量过量的铂促进剂和苛刻的还原条件。
