Plasmonic coupling enhancement of core-shell Au@Pt assemblies on ZnIn2S4 nanosheets towards photocatalytic H2 production

Hybrid Plasmonic Nanomaterials for Hydrogen Generation and Carbon Dioxide Reduction

“…More detailed investigation should be focused on unraveling the origin of the plasmonic enhancement. For example, electrochemically in situ Raman 190 and Fourier transform infrared spectroscopy (FTIR) 270 can be employed to unveil the plasmon-enhanced photoelectrocatalytic reaction mechanisms. These methods employed with and without light irradiation could provide some insight into how the plasmon excitation changes the reaction pathway of electrocatalytic processes on plasmonic electrodes.…”

Construction of Highly Efficient Photocatalyst with Core‐Shell Au@Ag/C@SiO2 Hybrid Structure towards Visible‐Light‐Driven Photocatalytic Reduction

“…[ 34,43 ] Besides that, the SPR peaks of Au@Ag NPs become broad on carbon microspheres, and the absorption remarkably enhances in visible region, which is caused by the SPR coupling effect of adjacent NPs. [ 1 ] When Au@Ag/C is further coated by a thin SiO 2 layer, the light absorption becomes stronger in comparison with those of Au@Ag/C, which is caused by the fact that the thin SiO 2 layer serves as an…”

“…Photocatalysis technology has gained much attention because of its green, renewable and mild reaction properties, which aroused wild interest in various fields including environmental remediation, water splitting, CO 2 reduction, and so on. [ 1‐9 ] The light‐driven organic transformation provides a sustainable pathway for green synthesis under mild condition, [ 10‐12 ] such as the photocatalytic reduction of nitrobenzene to produce aniline, which is of importance for both fundamental research and chemical industry. [ 13 ] Actually, tremendous efforts have been made to reduce nitrobenzene for aniline by photocatalysis process during past decades.…”

Synthesis of ZnIn2S4@Co3S4 particles derived from ZIF-67 for photocatalytic hydrogen production

“…However, for photocatalytic hydrogen evolution, ZnIn 2 S 4 still faces some challenges to increase the activity, such as how to enhance the response of visible light and improve the transfer and separation efficiency of photogenerated charge carriers. A number of strategies have been explored to modify ZnIn 2 S 4 for potential practical applications including structure and morphology controlling (nanoparticle, 15 nanosheets, 16 microsphere 17 ), element doping (copper, 18 nitrogen, 19 alkaline-earth metal 20 ), co-catalyst modifying (Au@Pt, 21 26 reported that hexagonal ZnIn 2 S 4 photocatalysts with different crystallinity and morphology were synthesized under different mediated conditions, exhibiting different photocatalytic properties. Shen et al 18 prepared a series of ZnIn 2 S 4 doped with different amounts of copper with improved photocatalytic activity.…”
