Recent observations of chemically induced hot electron flow over Schottky barriers in planar nanostructures provides interesting possibilities for electrolyte-free conversion of chemical energy into electricity and novel sensor applications. The work aims to make advantage of the nonthermal nature of the diabatic chemicurrents and explores the low-temperature (340-430K) chemovoltaic effect of hydrogen to water oxidation on Pt/GaP nanostructure surface. The chemicurrent is also studied at high pressures of the oxyhydrogen mixture diluted with nitrogen, all the way to atmospheric pressures. Separation of the diabatic component to the total generated current is performed with an accurate method based on resistive nanofilm heating.
