| Research Abstract |
Reduction of noble metal ions and subsequent production of noble metal particles in a solution has been performed as a radiation-induced reduction (RIR) method using high energy ionizing radiation for the synthesis of nano-sized catalyst particles. In the present study, low energy EBs have been studied for the production of such nano-sized noble metal catalysts in the whole solution and on the surface of catalyst substrates.
As a result, nano-sized platinum particles were produced in whole solution, which contains PtCl42- ions and ethanol, using even low energy EBs and were observed to have catalytic activity. Moreover, when porous alumina substrates, impregnated with such solution, was irradiated EBs, platinum particles were exclusively produced on the surface of the alumina substrates. The platinum particles had catalytic activity. The obtained results suggest that low energy EBs can be applied to the production of nano-sized noble metal catalysts as new application of RIP method.
