Catalyst Efficiency

A novel and green mechanochemical technique, the grinding-based method, was applied for synthesis of multi-metal cyanide (MMC) complexes. In order to discovery the effect of metal element on structure and catalyst efficiency, the obtained three MMCs were made from deferent three metal salts groups, which including ZnCl2 to NiCl2 to K3Fe(CN)6 molar ratio of 4:3:1 (MMC-1), ZnCl2 to NiCl2 to K3Co(CN)6 molar ratio of 4:4:1 (MMC-2), and ZnCl2 to NiCl2 to K4Fe(CN)6, respectively. And three MMCs were further used for copolymerization of CO2 and propylene oxide. FTIR and 1H NMR results shown, the alternating copolymerization obtained anticipated poly(propylene carbonate) with high catalytic activity. Comparing to the conventional solvent-based synthesis, the strikingly efficient and practically applicable grinding-based method reveals clear merits for syntheses of MMC complexes.
