Hydrogen Evolution on Zeolite Supported Platinum Clusters
Abstract
NaX type zeolite was loaded with platinum, by the thermal decomposition of Pt(II) acetylacetonate, up to the Pt/NaX mass ratio 0.174. The sample, dispersed on a glassy carbon rotating disc, was used in slightly acidic solution to observe the kinetics of the hydrogen evolution reaction. A comparison was made with the rate of hydrogen evolution on smooth polycrystalline platinum, and both slower and faster evolution rates were observed, depending on the percentage of carbon black added to the zeolite sample.
