Trace H<sub>2</sub>O<sub>2</sub>-triggered Fe/Mo-multistage DRCs driving H-bond network distortion of water molecules for enhancing self-purification capacity of micro-polluted water
<p indent="0mm">以化学氧化为主的水自净化过程依赖于惰性的溶解氧分子与结构稳定的新污染物(emerging contaminants, ECs)间随机且无序的相互作用, 导致水自净化效率极低. 本研究提出了一种创新策略, 通过制备具有极性强化的双反应中心催化剂(LLWR-FMS), 构建催化剂表面吸附的ECs与水中内源性介质间电子传递通道, 强化二者间相互作用, 能有效扩增水体自净力. 实验表明, 在天然江水体系中, LLWR-FMS扩增型水自净化体系能去除水中90%以上的环丙沙星, 且表现出极佳的适应性和良好的稳定性. 在仅<sc>0.1 mmol/L</sc>的H<sub>2</sub>O<sub>2</sub>微调控下, LLWR-FMS体系对江水体系中盐酸四环素的去除率在<sc>15 min</sc>内甚至能提高约50%.
