Abstract

Porous organic polymers (POPs) having very high surface areas, tunable pore volumes, excellent stabilities and controllable chemical composition have recently emerged a growing research interest as a most promising molecular nanoarchitecture for binding of metal or metal oxide nanoparticles (NPs) in the development of new advanced heterogeneous catalysts. Here in this featured article, we have focused on development of various kinds of POPs and immobilization of NPs in the framework of these POPs with their prospective employment as heterogeneous nanocatalysts to catalyze several catalytic reactions. These POP-based materials exhibit superior catalytic performance in coupling, hydrogenation and various acid catalyzed reactions with tremendous recyclability and combination of best features of both homogeneous and heterogeneous catalysts.

Highlights

The synthesis of Porous Organic Polymer (POP) support metal and metal oxides, it has received an increasing attention over the last decade in interdisciplinary research area for the development of new heterogeneous catalysts owing to their high chemical activity and wide-ranging applicability [1,2]
An additional stability and progressive catalytic activity of metal NPs in Porous Organic Polymer compared with the other catalytic supports is obtained owing to the interaction between organic linkers in POPs and metal NPs that can be readily enhanced by introducing coordination groups into metal precursors
They have found that Pd@OIP-2 offers higher catalytic activity and recyclability at least 6th competitive run without significant loss of catalytic activity compared with Pd@OIP-1 with their exposed Pd(111) crystalline facets making a better contact between substrate and catalytic active Pd-sites
