Title: Enhanced photocatalytic H{sub 2} evolution over CdS/Au/g-C{sub 3}N{sub 4} composite photocatalyst under visible-light irradiation

Abstract

A novel heterojunction structured composite photocatalyst CdS/Au/g-C{sub 3}N{sub 4} has been developed by depositing CdS/Au with a core (Au)-shell (CdS) structure on the surface of g-C{sub 3}N{sub 4}. The photocatalytic hydrogen production activity of the developed photocatalyst was evaluated under visible-light irradiation (λ > 420 nm) using methanol as a sacrificial reagent. As a result, its activity is about 125.8 times higher than that of g-C{sub 3}N{sub 4} and is even much higher than that of Pt/g-C{sub 3}N{sub 4}. The enhancement in photocatalytic activity is attributed to efficient separation of the photoexcited charges due to the anisotropic junction in the CdS/Au/g-C{sub 3}N{sub 4} system.
