Efficient and recyclable performance of organic-inorganic zirconium phosphonates supported salen-Mn(III) as catalysts for CO2 cycloaddition

摘要

In this research, organic-inorganic zirconium phosphonates were modified by salen-Mn(III) and formed novel heterogeneous catalysts using to CO2 cycloaddition for the first time. Specially, the supported catalyst lc indicate excellent catalytic activities (conv%, up to 95.8; sele%, up to 94.8) in the absence of solvent. Moreover, this heterogeneous catalyst could still show good catalytic ability after recycling seven times.
