Surface Cu+ modified ZnIn2S4 for promoted visible-light photocatalytic hydrogen evolution
文献摘要：
Surface modification by metal ion has been considered a promising strategy to enhance the photocat-alytic activity by extending optical response and improving charge separation and transportation.Here,univalent copper species were modified on ZnIn2S4 photocatalyst via an in-situ photodeposition method,exhibiting a much higher H2 evolution rate of 41.10±3.43 mmol g-1 h-1 and an impressive apparent quantum efficiency(AQE)of 20.81％at 420±15 nm.Our characterizations indicate that the sur-face modification by copper species can broaden light utilization as well as promote charge separation and transportation.Besides,the density functional theory(DFT)results further exhibit that the energy levels(LUMO and HOMO)for copper-surface modified ZnIn2S4 present spatial separation,locating on the Zn-S and In-S layers,respectively,which can suppress the recombination of electron and hole and thus achieves higher photocatalvtic H2 evolution efficiency.
