講座內容:

        Is there a correlation between activity and stability in single-atom catalysis? In coordination chemistry, catalytically active  l complexes in zero or low valent state often adopt four-coordinate square-planar or tetrahedron geometry. By applying this principle, we have developed stable, high loading (close to 1 wt%), Pt1 single-atom catalyst on phosphomolybdic acid (PMA) modified active carbon (AC), by anchoring Pt atoms on the four-fold hollow sites on PMA. Each Pt atom is stabilized by four surrounding oxygen atoms in a distorted square-planar geometry, with Pt slightly protruding from the oxygen planar surface. Pt is positively charged, easily absorbs hydrogen, and exhibits excellent activity and selectivity in the hydrogenation of nitrobenzene and cyclohexanone. Following that, we briefly discuss the extension of the strategy to several other stable SACs with superior catalytic activities. These SACs have distinct stability but strikingly similar activity. Kinetic study and DFT calculations into the rate-determining steps provide insights on why is this so. Finally, we introduce our recent work on the development of Rh single-atom catalysts for CO oxidation reactions.
