Electrode-Modified Zeolites - Electrode Microstructures Contained in and on a Heterogeneous Catalyst
Abstract
In this work, zeolite-supported Pt(O) microstructures sized less than 10 nm are accessed as electrodes using dispersion electrolysis. Modification of an heterogeneous catalyst with ultramicroelectrodes permits exploration of electrode processes in an interphase dominated by the nature of the heterogeneous catalyst and at electrode sizes where bulk metallic properties may not apply. The systems described are Pt supported on zeolite Type Y and Pt supported on gamma-alumina. The electrolytic response of zeolite-supported Platinum in the absence of added electrolyte salt for water or benzene: Water is markedly more effective than that at alumina-supported Pt and is seen to depend on the size of the Pt particles supported on the exterior of the zeolite surface. Both supported systems behave as ultramicroelectrodes in that electrolysis is sustained in their presence under conditions that are strictly ohmic for the feeder electrodes due to the high resistivity of the media in the absence of electrolyte salt.
