| Research Abstract |
A novel method to prepare the nano-sized metal catalysts is proposed. Mesoporous silicas or zeolites containing highly dispersed titanium oxide species (single-site photocatalysts) can act as the platform to generate highly dispersed metal particles. Characterization by XAFS, CO adsorption, and TEM analyses revealed that the size-controlled metal particles were obtained. These nano-sized metal catalysts are useful as efficient catalysts for various reactions such as NO reduction, H_2O_2 formation from H_2 and O_2, etc. The present technique using single-site photocatalysts make a great contribution to minimize the amount of precious metal materials.
