Abstract

Hydrogen gas as a clear energy resource was found to be largely bubbled from a H2O/H2O2/MnWO4 system. MnWO4 powder was fabricated by an aqueous reaction method. The powder was characterized with X-ray diffraction (XRD), transmission electron microscope (TEM), and X-ray photoelectron spectrometry (XPS). The efficiency of the hydrogen generation increases with an increase in initial pH in the appropriate range, H2O2 proportion, MnWO4 proportion, and intensity of light resource. Calcining at 400 °C for 1 h can make the MnWO4 powder synthesized by an aqueous reaction more effective for H2 generation and more stable in higher initial pH. The MnWO4 catalyst shows a long-term stability for photocatalytic H2 generation. A mechanism was suggested for the hydrogen generation from the H2O/H2O2/MnWO4 system together with XPS analysis.
