Enhanced catalytic activity of a hierarchical porous metal–organic framework CuBTC

A previously reported mixed ligand strategy was used to synthesize a classic metal–organic framework CuBTC, which exhibited a hierarchical porous structure including micropores and around 3.9 nm. Thanks to the facile mass transfer and denser open metal sites induced by the mixed ligand strategy, the hierarchical porous CuBTC demonstrates enhanced catalytic activity towards both the ring-opening reaction of styrene oxide to 2-methoxy-2-phenylethanol and the cyanosilylation reaction of benzaldehyde to cyanohydrins.
