In recent years, finding novel photocatalysts that can operate at a broad range of wavelengths is interesting in photocatalytic research filed. Here, a metallic/semiconducting HxWO3/WO3 nanoheterostructure is prepared with ability to degrade organic dyes and to produce photocurrent under visible and near-infrared (NIR) irradiation. The metallic HxWO3 is helpful for electrons transfer then to enhance photocatalytic activity. The HxWO3/WO3 nanoheterostructure exhibits excellent photoelectric conversion characteristics in infrared wavelength range. Strong interfacial contact between two components is advantaged for fabrication of photovoltaic device, indicating its potential application as an infrared photovoltaic cell.
