“…[ 78 ] These coupled nanostructures possess multi‐interfacial plasmonic coupling effect with abundant active sites, enhanced light trapping ability, and strongly coupled near‐field, which enable potential applications for solar‐driven reactions. [ 78 ] Besides, polymer‐assisted and template‐supported synthetic methods were also employed to prepare coupled nanostructures, such as Au@SiO 2 dual shell NPs, [ 76 ] Au core–Ag satellite nanostructures, [ 107 ] Au core–satellite nanostructures, [ 108 ] Au‐nanobridged NPs, [ 109 ] porous triple‐shell Au nanostructures, [ 110 ] and hollow bilayer shell Au‐Au/Pd/Pt nanocatalosomes (Figure 8b,c).

Plasmonic photocatalysis is a promising approach for solar energy transformation. Comparing with isolated metal nanoparticles, the plasmonic coupling architectures can provide further strengthened local electromagnetic field and boosted light‐harvesting capability through optimal control over the composition, spacing, and orientation of individual nanocomponents. As such, when integrated with semiconductor photocatalysts, the coupled metal nanostructures can dramatically promote exciton generation and separation through plasmonic‐coupling‐driven charge/energy transfer toward superior photocatalytic efficiencies. Herein, the principles of the plasmonic coupling effect are presented and recent progress on the construction of plasmonic coupling architectures and their integration with semiconductors for enhanced photocatalytic reactions is summarized. In addition, the remaining challenges as to the rational design and utilization of plasmon coupling structures are elaborated, and some prospects to inspire new opportunities on the future development of plasmonic coupling structures for efficient and sustainable light‐driven reactions are raised.

Insufficient light absorption and low carrier separation/transfer efficiency constitute two key issues that hinder the development of efficient photocatalytic hydrogen production. Here, multishell ZnS/CoS2 bisulfide microspheres with gradient distribution of Zn based on the heat diffusion theory are designed. The Zn distribution can be adjusted by regulating the heating rate and manipulating the diffusion coefficients of the different elements conforming the multishell photocatalyst. Because of the unique structure, a gradient energy level is created from the core to the exterior of the multishell microspheres, which effectively facilitates the exciton separation and electron transfer. In addition, stronger light absorption and larger specific surface area have been achieved in the multishell ZnS/CoS2 photocatalysts. As a result, the multishell ZnS/CoS2 microspheres with gradient distribution of Zn exhibit a remarkable hydrogen production rate of 8001 µmol g−1 h−1, which is 3.5 times higher than that of the normal multishell ZnS/CoS2 particles with well‐distributed Zn and 11.3 times higher than that of the mixed nonshell ZnS and CoS2 particles. This work demonstrates for the first time that controlling the diffusion rate of the different elements in the semiconductor is an effective route to simultaneously regulate morphology and structure to design highly efficient photocatalysts.

“…Metallic HoMSs are recently demonstrated by Au HoMSs using Au melamine colloidal templates. [ 129 ] By LSPR effects of Au subunits, visible light is absorbed and massive hot electrons on the Au surfaces are generated via the surface plasmon decay process. These hot electrons promote dissociation of absorbed hydrogen sources and further reduce the adjacent ‐NO 2 groups, showing significantly improved activity and selectivity for hydrogenation of 4‐nitrostyrene.…”
