Electrocatalytic reduction of CO₂ to CO was achieved by using nitrogen‐doped Ta₂O₅, and the faradaic efficiency of CO reached 87.5 % at −0.73 V vs. RHE, whereas undoped Ta₂O₅ or “fully doped” Ta₃N₅ only yields H₂. Nitrogen‐doped Ta₂O₅ was also a catalyst for photoassisted electrocatalytic CO₂ reduction, and the total light‐to‐chemical efficiency reached 2.73 %.

氮掺杂的Ta2O5纳米复合材料，可在光助催化下将二氧化碳电催化还原为CO

通过使用氮掺杂的Ta ₂ O ₅将CO ₂电催化还原为CO，在-0.73 V相对于RHE的条件下，CO的法拉第效率达到87.5％，而未掺杂的Ta ₂ O ₅或“完全掺杂”的Ta ₃ N ₅仅产生H ₂。氮掺杂的Ta ₂ O ₅也是光辅助电催化CO ₂还原的催化剂，总光化学效率达到2.73％。
