Micrometre‐Sized Porous Polymer Beads as Heterogeneous Molecular Catalysts

Abstract

Porous polymers have great potential as versatile, chemically stable catalyst supports. Yet, shaping of the resulting powders remains a challenge. Here, we demonstrate the use of suspension polymerisation to design micrometre‐sized porous polymers beads containing metal binding sites. The good accessibility of the binding sites ensures high catalytic activity, which is demonstrated for two model reactions: photochemical CO2 reduction and transfer hydrogenation of aromatic ketones. Importantly, the shaping of the host material does not affect the catalytic activity of the active site.

Molecular Rhodium Complex within N‐Rich Porous Polymer Macroligand as Heterogeneous Catalyst for the Visible‐Light Driven CO2 Photoreduction

“…Note that for all those reports different mass loadings, catalyst loadings, and particle sizes have been used, parameters that all affect the photocatalytic activity (Figure 4a). [36,40,41] However, even when using higher mass loading of 1.5 wt% Cp*Rh@N-POP, this catalyst still outperforms the aforementioned single-site Rh and Ru catalyst with R of 10.2 and 8.5 mmol HCOOH /g cat /h for loadings of 0.35 and 0.5 mg mL À1 (conditions often used in literature), respectively.…”
