Carbonylation Reactions Using Single-Atom Catalysts

The development of highly efficient and selective catalysts for carbonylation reactions represents a significant challenge in catalysis. Single-atom catalysts (SACs) have postulated as promising candidates able to combine the strengths of both homogeneous and heterogeneous catalysts. In this paper, we review recent advances in tailoring solid supports for SACs to enhance their catalytic performance in carbonylation reactions. We first discuss the effect of supports on the hydroformylation reaction catalysed by SACs, followed by recent advances for methanol, ethanol, and dimethyl ether carbonylation reactions, focusing on the design of halide-free catalysts with improved activity and stability. Finally, oxidative carbonylation is discussed. Overall, this review highlights the importance of tailoring solid supports for SACs to achieve highly active and selective catalysts in carbonylation reactions, paving the way for future developments in sustainable catalysis. This minireview explores recent advances in tailoring solid supports for single-atom catalysts (SACs) to enhance their catalytic performance in carbonylation reactions, including hydroformylation, methanol carbonylation, and oxidative carbonylation as the main reactions. The review underscores the importance of optimizing solid supports for SACs to achieve highly active and selective catalysts in these reactions. It also emphasizes the need to combine advanced in situ/operando characterization techniques and theoretical calculations to gain further insights and provide structure-property correlations, paving the way for future developments in sustainable catalysis. image
