3D Urchin-Like CuO Modified W₁₈O₄₉ Nanostructures for Promoted Photocatalytic Hydrogen Evolution under Visible Light Irradiation.

ABSTRACT: Photocatalytic hydrogen evolution is a promising" green chemistry" route driven by sunlight for the direct water splitting into value-added hydrogen energy. Herein, with the object of exploring the effect of CuO loading on W₁₈O₄₉ photocatalytic activity, a 3D Urchin-like CuO modified W₁₈O₄₉ (CuO/W₁₈O₄₉) microspheres with different CuO loadings were synthesized via thermochemical precipitation combined with solvent-thermal method. The obtained CuO/W₁₈O₄₉ microspheres were analyzed by means of X-ray diffraction (XRD), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS) and photoluminescence (PL), etc
