| 英文摘要 | In this study, electron-deficient boron and electron-rich nitrogen are designed as the B/N Lewis pair to capture HCHO, and in next step the adsorbed HCHO is degraded into CO2 and H2O (mineralization efficiency 97 %) via the Fenton-like O2 activation and generation singlet oxygen (1O2), superoxide radicals (鈥2鈭? and hydroxyl radicals (鈥H) derived from the interaction between palladium nanoparticles and oxygen molecules. Experimental data and theoretical calculations reveal the optimal path as follows: HCHO + OH* (鈥H) 鈫?HCHOOH* 鈫?HCOOH + OH* (鈥H) 鈫?CHO2* + O* (1O2 and 鈥2鈭? 鈫?CO2, which correspond to the lowest energy barrier for elementary reaction. This study demonstrates a strong catalytic HCHO oxidation process and a new insights into exploiting synergetic palladium-modulated and B/N Lewis pair-functionalized flocculent carbon fibres for room-temperature HCHO decomposition. 漏 2022 Elsevier B.V. |
