摘要：In this work, a photocatalytic system containing ZnO "nanograss", Eosin Y and Pt was fabricated on an ITO substrate, and its photocatalytic activity was investigated for H-2 evolution under visible irradiation. The results indicate that this photocatalytic system possesses high activity for visible-light-driven H-2 evolution. A rate of H-2 evolution of approximate 0.46 L m(-2) h(-1) was achieved under optimal condition, which is 1.26 times higher than that of the Eosin Y sensitized ZnO nanoparticles immobilized on the ITO substrate. At last, the enhancement mechanism of the photocatalytic activity was preliminarily discussed using photoelectrochemical techniques. An efficient photocatalytic system containing ZnO "nanograsses", Eosin Y and Pt is fabricated on a solid substrate for visible-light-driven H-2 evolution. Therein, the ZnO "nanograss" serves as an efficient light harvesting block and an electron transfer channel. [GRAPHICS] .
