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

Abstract

Traditionally, the immobilized catalyst sacrifices a part of catalytic activity for its recyclability. To reproduce the catalytic activity of active specie, we construct a novel strategy called "adsorption-desorption-adsorption". Since the...

Enhancement of the catalytic performance of UIO-66 for the CO2 synthesis of cyclic carbonate using natural nanomaterials as a carrier

“…Compared to these carrier materials, our previous work demonstrated that as a natural nanocatalyst carrier, ATP is more readily available and has excellent CO 2 fixation capacity. 16,17 In addition, it has been demonstrated that the catalytic effect tends to be better when multiple catalyst sites coexist, such as when both metal Lewis acidic sites and Lewis basic sites are included. 18,19 Our group proposes to prepare loaded catalysts using a natural product, attapulgite (ATP), as a carrier to improve the efficiency of the UIO-66 catalyst by using the Lewis alkaline site of ATP pores and Lewis acid sites in the skeleton, as shown in Fig.…”
