Red-Light-Induced Ligand-to-Metal Charge Transfer Catalysis by …
2 天之前 · Photoinduced ligand-to-metal charge transfer (LMCT) is a powerful technique for the formation of reactive radical species via homolytic cleavage of the metal–ligand bond. Here, we present that the excited state LMCT of a cobyrinate complex can be accessed by tuning its axial coordination with thiolates as ligands. We demonstrate the photoreduction of cobalt via the excited state Co–S bond ...

A minireview on the synthesis of single atom catalysts - PMC
The two routes for the synthesis of SACs are reviewed and the advantages and disadvantages of each method are compared. 1. Introduction. Single atom catalysis describes a process in which a single atom on a catalyst surface drives a catalytic reaction. 1,2 The catalyst with a single atom on its surface is called a single atom catalyst (SAC). The …
Tailoring catalysis at the atomic level: trends and breakthroughs in ...
2024年12月5日 · Owing to a very small amount of catalyst used in the reaction (Pd, 0.036 mol% based on benzene), a turnover number of 363 was obtained which was higher than that obtained for the homogeneous Pd(OAc) 2 catalyst. The catalytic system exhibited excellent recyclability up to three reaction cycles (20.7% yield in the third cycle) and it was observed ...
