TL;DR
This paper studies how to best attach a rhenium catalyst inside a metal-organic framework to efficiently convert CO2 into CO using light.
Contribution
The study identifies solvent-assisted ligand incorporation as the optimal method for anchoring a rhenium catalyst in a MOF for CO2 reduction.
Findings
Solvent-assisted ligand incorporation minimizes rhenium leaching compared to physical entrapment and electrostatic anchoring.
Installation mode affects the electronic properties and catalytic activity of the rhenium catalyst.
Optimal Re loading and concentration in the MOF matrix were determined for efficient CO2 reduction.
Abstract
This study explores the impact of (i) different installation modes of the molecular rhenium catalyst Re within the PCN‐777 metal–organic framework (MOF) and (ii) catalyst loading on the resulting catalytic performance and recyclability of the different hybrid materials in the photocatalytic reduction of CO2 to CO. Through systematic investigation, we demonstrate that a robust coordination linkage between a zirconium node of the framework and the catalyst, obtained via solvent‐assisted ligand incorporation (SALI), minimizes rhenium leaching. In contrast, physical entrapment and electrostatic anchoring methods result in significant rhenium leaching after installation. Additionally, we reveal how the installation mode influences the electronic properties of the catalyst, which allows us to tune the catalytic activity. Furthermore, based on these results, we determine the optimal loading…
