Enhancement of the catalytic performance of UIO-66 for the CO synthesis of cyclic carbonate using natural nanomaterials as a carrier.

One of the environmentally friendly methods is the intelligent utilization of natural one-dimensional nanomaterials as carriers to improve the CO catalytic performance of MOF materials. This paper reports an efficient composite catalyst preparation using a cheap and readily available magnesium-aluminosilicate nanometer, attapulgite (ATP), as a carrier for MOF materials. Due to its Lewis acidic site and unique alkaline pore structure, ATP exhibits excellent catalytic activity in the coupling reaction of CO with epoxy compounds, and its regular one-dimensional nanorod shape has tremendous potential as a carrier compared to other natural minerals.

Getting rid of the shackles from the support: construction of recoverable semi-homogeneous catalysts with attapulgite.

Traditionally, immobilized catalysts sacrifice part of their catalytic activity for their recyclability. To reproduce the catalytic activity of these active species, we construct a novel strategy called "adsorption-desorption-adsorption". Since the active material and the support of the catalyst are connected by an electrostatic force, the catalyst can release the active material into the solvent during the heating process of the reaction to achieve the effect of homogeneous catalysis.
