Abstract

In the present study, the reduction of PtCl62− ions and subsequent formation of Pt particles were examined for a few tens keV EB irradiation of PtCl62− ion solution in the presence of 1 - 20 wt% ethanol as an OH radical scavenger. As a result, the reduction of PtCl62− ions proceeded in whole solution by irradiating only the topmost surface layer of the solution, and these Pt particles with sizes of 2 - 5 nm would be produced as primary particles through reduction of PtCl62− ions. Moreover, these Pt particles were observed to have hydrogen dissociation activity and oxidation activity.
