Photocatalysis encompasses many charge-generation and transfer mechanisms as well as photothermal mechanisms. Plasmonics is an emerging field of photocatalysis based in the concept that nanoparticles, most commonly noble metals, can be light "activated" when illuminated at their plasmonic resonance frequency, which is dependent on the material, size and morphology. While the precise mechanism is not fully explored in detail in this study, we focus on the photothermal activation of TiN when illuminated with red light (625 nm), UV light (385 nm), and a broad-spectrum white light LED, all capable of activating TiN, TiO2, and titanium oxynitride (TiOxNy). TiN is of particular interest as it is one of the only non-noble metal plasmonic materials that is earth abundant, has optical properties similar to gold, and remains structurally stable and plasmonically active even when partially oxidized. This photo-driven process offers significant benefits in terms of scalability, modularity, and applicability across diverse environmental conditions, while also laying the foundation for future advancements in photoreactive carbon capture and conversion to value-added products.
