Gold nanoparticles are attractive in catalytic field due to their high activity and selectivity. However, dispersion and sintering resistance have been two of the biggest issues in catalysis for preparation of gold nanoparticles. In this paper, a controlled impregnation method was employed to prepare highly dispersed and thermally stable Au-based catalysts for aerobic oxidation of benzyl alcohol....
Controlled synthesis of bimetallic catalysts has attracted much attention in heterogeneous catalysis because their catalytic activity depends on the size of nanoparticles and hence the methods of synthesis. In this work, one convenient method was proposed, with an aim to control the size and dispersion of bimetallic nanoparticles. In this method, Cu2+ (or Ni2+) configurational ion of hydrotalcites...
