Non-metal (i.e., P) and non-noble metal (i.e., Cu) doped semiconductor promoted P/Cu/CuO/Cu3(PO4)2/TNP nanocomposite with excellent natural solar light driven photocatalytic hydrogen production performance was fabricated using a sol-gel and followed by photo-assisted reduction method. Compared to other nanocomposites, P/Cu/CuO/Cu3(PO4)2/TNP displayed more superior photocatalytic hydrogen production yield, which is 151 fold higher than that of TNP. The improved photocatalytic hydrogen production activities could be attributed that suppressing the recombination of charge carriers, preferable absorption ability and high surface area values of P/Cu/CuO/Cu3(PO4)2/TNP, which were confirmed with XRD, TPR, DRS, HRTEM, Surface area, XPS, EPR, Raman and PL techniques. |
