Plasmonic photocatalysis is among the most efficient processes for the photoreduction of CO into valuable fuels. The formation of localized surface plasmon resonance (LSPR), energy transfer, and surface reaction are the significant steps in this process. LSPR plays an essential role in the performance of plasmonic photocatalysts as it promotes an excellent, light absorption over a broad wavelength range while simultaneously facilitating an efficient energy transfer to semiconductors. The LSPR transfers energy to a semiconductor through various mechanisms, which have both advantages and disadvantages. This work points out four critical features for plasmonic photocatalyst design, that is, plasmonic materials, size, shape of plasmonic nanoparticles (PNPs), and the contact between PNPs and semiconductor. Various developed plasmonic photocatalysts, as well as their photocatalytic performance in CO photoreduction, are reviewed and discussed. Finally, perspectives of advanced architectures and structural engineering for plasmonic photocatalyst design are put forward with high expectations to achieve an efficient CO photoreduction shortly.

Designing and optimizing photocatalysts to maximize the use of sunlight and achieve fast charge transport remains a goal of photocatalysis technology. Herein, a full-spectrum-response BiOBr:Er@BiO core-shell S-scheme heterojunction is designed with [Bi─O] tetrahedral sharing using upconversion (UC) functionality, photothermal effects, and interfacial engineering. The UC function of Er and plasmon resonance effect of BiO greatly improves the utilization of sunlight.

Plasmonic catalysis, whereby either an optically resonating metal couples to a catalytic material or a catalytic metal particle achieves optical resonance, has been a mainstay of photo-catalysis research for the past few decades. However, a new field of metal-dielectric metamaterials, including plasmonic metamaterials, is emerging as the next frontier in catalysis research. With new optical behaviors that can be achieved by sub-wavelength structures, in either periodic or semi-periodic arrangements, metamaterials can overcome some of the limitations of conventional plasmonic catalysis.

We report here a BiWO/TiCT@Ag (BT@Ag) photothermal photocatalyst for efficient CO reduction with tunable CH selectivity. Incorporation of TiCT MXene creates well-defined heterointerfaces between BiWO and TiCT and converts thermal energy upon light illumination via photothermal effect, which contributes to a mitigation of the recombination of photo-induced charge carries for a high electron mobility. Density functional theory calculations substantiate that TiCT functions as the adsorption site and active center where the transferred electrons are effectively involved in CO reduction for enhanced CH selectivity.

Hydrogen is increasingly acknowledged as a viable alternative to traditional fossil fuels. However, the photothermal properties of CoFeS, a photocatalyst displaying metal-like behavior, have not been adequately explored in the context of photocatalytic H generation. To improve photocatalytic hydrogen evolution, it is crucial to understand how to expedite the transfer of photogenerated electrons and the dissociation of H-OH bonds for enhanced hydrogen ion release.
