“…The broad LSPR observed in metal nitrides can make them attractive materials to drive photochemical reactions using sunlight, but the rapid thermalization of excited electrons in plasmonic metal nitrides can make it difficult to effectively harvest hot electrons . Nevertheless, a handful of investigations have been led toward plasmon enhanced water-splitting, − CO 2 and HCO 3 – reduction, , and photocatalytic disinfection using plasmonic metal nitride nanostructures. In most studies, the nitrides are used as sensitizers to extend the absorption spectrum of a semiconductor (e.g., TiO 2 , CdS, In 2 O 3– x (OH) y ) into the visible and near-IR region.…”

Metal nitride nanostructures have been predicted to exhibit plasmonic responses in the UV to IR region, which can enable their potential use as low-cost, chemically, and thermally stable materials in several applications. In the case of photothermal applications, nitrides have been shown, both numerically and experimentally, to perform better than the noble metals. Additionally superior thermal stability of the metal nitride materials offers compatibility with high temperature device fabrication techniques. The plasmon frequency for transition metal nitride materials can be tuned from the UV to IR region by varying the type of metal in the nitride and metal/nitrogen ratio. Recently, studies have focused on developing and applying free-standing metal nitride nanostructures. Most investigations have focused on TiN, but as of late focus has been shifting to investigate other nanostructured nitrides such as ZrN and HfN. This Perspective will highlight recent key findings on the synthesis of plasmonic metal nitrides; associated thermal stability and photothermal properties; and application in photothermal therapy, solar-driven water evaporation, and chemical reactions. An outlook on current knowledge gaps and challenges and future directions to further this field is also presented.

“…In such cases, the generated excitons have higher energy than the Fermi level of the photocatalyst, which is ideal for driving photocatalytic reactions [108]. For example, ZrN [109], HfN [110] and TiN [111] are reported as plasmonic metal nitride nanostructures. However, Cu 3 N has not yet been specifically reported as a plasmonic nanomaterial.…”

This review addresses the most recent advances in the synthesis approaches, fundamental properties and photocatalytic activity of Cu3N nanostructures. Herein, the effect of synthesis conditions, such as solvent, temperature, time and precursor on the precipitation of Cu3N and the formation of secondary phases of Cu and Cu2O are surveyed, with emphasis on shape and size control. Furthermore, Cu3N nanostructures possess excellent optical properties, including a narrow bandgap in the range of 0.2 eV–2 eV for visible light absorption. In that regard, understanding the effect of the electronic structure on the bandgap and on the optical properties of Cu3N is therefore of interest. In fact, the density of states in the d-band of Cu has an influence on the band gap of Cu3N. Moreover, the potential of Cu3N nanomaterials for photocatalytic dye-degradation originates from the presence of active sites, i.e., Cu and N vacancies on the surface of the nanoparticles. Plasmonic nanoparticles tend to enhance the efficiency of photocatalytic dye degradation of Cu3N. Nevertheless, combining them with other potent photocatalysts, such as TiO2 and MoS2, augments the efficiency to 99%. Finally, the review concludes with perspectives and future research opportunities for Cu3N-based nanostructures.

“…Beierle et al designed a titanium nitride-titanium dioxide nanocomposite for bicarbonate reduction to formate. This work demonstrated that under solar illumination, the TiN-TiO 2 nanocomposite has higher photocatalytic activity than bare TiN or TiO 2 , this nanocomposite can also greatly enhance formate production and remain stable for 8 h [44]. Baran et al synthesized nanocrystalline zinc sulfide surface-modified with ruthenium(0) for the photocatalytic CO 2 reduction to formate, carbon monoxide and methane [45].…”

Rising levels of atmospheric carbon dioxide due to the burning and depletion of fossil fuels is continuously raising environmental concerns about global warming and the future of our energy supply. Renewable energy, especially better utilization of solar energy, is a promising method for CO2 conversion and chemical storage. Research in the solar fuels area is focused on designing novel catalysts and developing new conversion pathways. In this review, we focus on the photocatalytic reduction of CO2 primarily in its neutral pH species of carbonate to formate. The first two-electron photoproduct of carbon dioxide, a case for formate (or formic acid) is made in this review based on its value as; an important chemical feedstock, a hydrogen storage material, an intermediate to methanol, a high-octane fuel and broad application in fuel cells. This review focuses specifically on the following photocatalysts: semiconductors, phthalocyanines as photosensitizers and membrane devices and metal-organic frameworks.
