Abstract\ One of the central tasks in the field of heterogeneous catalysis is to establish structure-function relationships for these catalysts, especially for precious metals dispersed on the sub-nanometer scale. Here, we report the preparation of MgAl2O4-supported Pt nanoparticles, amorphous aggregates and single atoms, and evaluate their ability to catalyze the hydrogenation of benzaldehyde. The Pt species were characterized by N-2 adsorption, X-ray diffraction (XRD), aberration-corrected transmission electron microscopy (ACTEM), CO chemisorption and in situ Fourier transform infrared spectroscopy of the chemisorbed CO, as well as by inductively coupled plasma atomic emission spectroscopy. They existed as isolated or neighboring single atoms on the MgAl2O4 support, and formed amorphous Pt aggregates and then nanocrystallites with increased Pt loading. On the MgAl2O4 support, single Pt atoms were highly active in the selective catalytic hydrogenation of benzaldehyde to benzyl alcohol. The terrace atoms of the Pt particles were more active but less selective; this was presumably due to their ability to form bridged carbonyl adsorbates. The MgAl2O4-supported single-atom Pt catalyst is a novel catalyst with a high precious atom efficiency and excellent catalytic hydrogenation ability and selectivity.
