Gas phase photocatalytic water splitting with Rh2−yCryO3/GaN:ZnO in μ-reactors

Author affiliations

Abstract

Rh2−yCryO3/GaN:ZnO has been tested for gas phase overall photocatalytic water splitting by dosing water vapor. The sample has been deposited in a μ-reactor and evolves hydrogen and oxygen under illumination of solar light. This experiment proves the possibility to study solar active materials and the mechanism of the water splitting reaction with gas phase experiments. The high impact of the relative humidity on the activity has been shown by changing the water partial pressure and the reactor temperature.
