Recent Progress on Photocatalytic CO2 Conversion Reactions over Plasmonic Metal-based Catalysts

“…Photocatalytic CO 2 reactions can be catalyzed by plasmonic metal-based catalysts. Adjusting the size, morphology, and other properties of plasmonic NPs could increase and tailor their light absorption properties. , In addition, by loading the PNPs on the semiconductor support, a Schottky barrier or Ohmic junction could be formed at the interface, which significantly improves the injection of hot electrons and the transfer of interfacial charge and ultimately boosts the catalytic performance.…”

“…In this review, we briefly introduced the latest progress of Au-, Ag-, and Cu-based plasmonic catalysts and other plasmonic catalysts in photocatalytic CO 2 with H 2 O, H 2 , CH 4 , and organic chemicals, as well as the mechanisms of photocatalytic CO 2 reduction reactions over these plasmonic metal-based catalysts.

Synthesis and Characterization of Nanocube Cu2O Thin Film at Room Temperature for Methylene Blue Photodegradation Application

“…The semiconductor can absorb light at a certain wavelength which causes a redox reaction in water on the surface of the material that produces radical. These radicals can oxidize organic compounds including MB resulting in decomposing of the structure [3]. Photodegradation methods have superiority such as low cost, ease of process, and environmental friendliness [4].…”

Electrical and Thermal Conductivities of Single CuxO Nanowires

“…Polycrystalline CuO NWs are also promising for resistive switching applications, where the presence of different oxide phases and high density of defects can locally enhance the electric field, facilitating the oxygen vacancies' diffusion through the nanostructure [29][30][31]. In the field of optoelectronics, CuO NWs have demonstrated potential applications in photodetectors, photovoltaics, and photocatalysis due to their ptype semiconducting behavior, unique bandgap tunability, light absorption properties, and their photocatalytic activity when coupled with a noble metal or coated with other metaloxides for the realization of p-n heterojunctions based on semiconducting NWs [32][33][34][35][36][37][38]. Overall, the thermal growth of CuO or Cu 2 O NWs directly on copper foil offers potential for advancing electronic devices and sensors, paving the way for high-performance, costeffective, and environmentally friendly technological solutions [28].…”
