摘要：
A 64-fold improved efficiency of solar-to-hydrogen conversion (SHC) was achieved via exposing Au nanoparticles (NPs) on the {001} facets of anatase TiO2 nanosheets. The SHC follows a surface plasmon resonance-mediated electron injection mechanism, where Au NPs can not only harvest visible light and convert them to free energetic electrons, but promote the SHC by increasing the electron-hole pair formation rate driven by the electromagnetic field formed nearby the semiconductor.
