An Efficient Nanoscale Heterogeneous Catalyst for the Capture and Conversion of Carbon Dioxide at Ambient Pressure

Silver nanoparticles were successfully supported on the zeolite‐type metal–organic framework MIL‐101 to yield Ag@MIL‐101 by a simple liquid impregnation method. For the first time, the conversion of terminal alkynes into propiolic acids with CO2 was achieved by the use of the Ag@MIL‐101 catalysts. Owing to the excellent catalytic activity, the reaction proceeded at atmospheric pressure and low temperature (50 °C). The Ag@MIL‐101 porous material is of outstanding bifunctional character as it is capable of simultaneously capturing and converting CO2 with low energy consumption and can be recovered easily by centrifugation. Silver nanoparticles were supported on the zeolite‐type metal–organic framework MIL‐101 by a simple liquid impregnation method to yield Ag@MIL‐101. CO2 and terminal alkynes could be converted into propiolic acids in the presence of the very active Ag@MIL‐101 catalyst at atmospheric pressure and low temperature (50 °C).
