abstract = {This study focuses on V2O3−x nanoparticles and systematically analyzes them as plasmonic solar-driven catalysts for the first time. It reveals that they exhibit the localized surface plasmon resonance (LSPR) absorption characteristics in the near-infrared regions. By integrating in-situ characterization and theoretical calculation results, the mechanism of in-situ generation of oxygen vacancies (Vo) in V2O3 under irradiation and subsequently transformed into catalytically active V2O3−x is elucidated. Furthermore, the process in which V2O3−x generates hot electrons and holes through plasmon damping is analyzed, as well as its excellent effects in increasing the local temperature, providing active sites, and enhancing the light absorption capacity. V2O3−x demonstrates excellent performance in the reverse water-gas shift (RWGS) reaction, with a CO conversion rate of 668.48 mmol·g−1·h−1, with a CO selectivity exceeding 99.9%, and long-term stability for 90 h, highlighting the great potential of metal oxide plasmas in solar-driven catalysis. This research provides crucial insights into enhancing the solar-chemical energy conversion efficiency by utilizing the synergistic effect of LSPR and intrinsic interband transitions.}
