▎ 摘　　要

The production of hydrogen (H-2) energy by photocatalysis of water splitting has been attracting a tremendous amount of attention as a clean and renewable energy generating system. Despite the enormous efforts being made, the present challenge in materials science is to build a highly active catalytic system with high efficiency and low cost. Herein, we report Pt-graphene/TiO2 nanocomposites produced through a fast and facile microwave-assisted technique. The "as-prepared" composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) analysis, transmission electron microscopy (TEM), UV-Vis absorbance spectra analysis, diffuse reflectance spectra (DRS) analysis and Raman spectroscopic analysis. The photocatalytic activity was investigated for H-2 evolution from aqueous solution containing a sacrificial reagent using UV light as an energy source.
