Plasma CO2 splitting to CO over oxygen-deficient Mo-doped CeO2 under mild conditions was investigated for the first time, showing ∼20 times higher CO2 conversion compared to pure CeO2, which can be attributed to the increased oxygen vacancies (VO) and the formation of Ce3+-VO-Mo on the catalyst surface. Importantly, VO sites showed excellent catalytic stability.
首次研究了在温和条件下，缺氧的钼掺杂二氧化铈上二氧化碳等离子体分解为一氧化碳的情况，结果表明，与纯二氧化铈相比，二氧化碳转化率提高了约20倍，这可归因于氧空位（VO）的增加以及催化剂表面形成的Ce3+-VO-Mo。重要的是，VO位点表现出优异的催化稳定性。
