摘要

异相钴基催化剂在过硫酸盐(PMS)活性和产生自由基方面非常有效,可用于处理水中的难降解有机污染物。然而,由于活性钴物种容易团聚和沥滤,其不可行的可回收性和逐渐退化的性能仍然具有挑战性。本文提出了一种在双功能磺化共价有机框架(COF-Co)上构建稳定锚定且高度分散的 Co2+ 位点的策略。磺酸基团能够通过两步阳离子交换法实现与钴离子的定向结合,从而与活性 Co2+ 位点强强联合,达到最高的利用效率。此外,磺酸基团的超亲水性有利于有机分子快速进入催化剂并加速降解。值得注意的是,COF-Co 在活化 PMS 方面表现出很高的活性,能有效氧化降解四环素(在 30 mg L-1 的条件下,30 分钟内降解 92%)和其他着色污染物,并具有出色的回收稳定性。这项工作可指导合理设计高效、环保的 PMS 活性催化剂,在废水处理中具有巨大的应用潜力。

Sulfonated Covalent Organic Frameworks Anchoring Cobalt as High-Efficient and Stable Catalysts for Peroxymonosulfate Activation.

Heterogeneous cobalt-based catalysts are highly effective in activing peroxymonosulfate (PMS) and produce free radicals to deal with recalcitrant organic pollutants in water. However, unfeasible recyclability and gradual performance degradation remain challenging due to the easy agglomeration and leaching of active cobalt species. Herein, a strategy is proposed to construct stably anchored and highly dispersed Co2+ sites on dual functional sulfonated covalent organic frameworks (COF-Co). The sulfonic acid groups are able to realize the targeted binding with cobalt ions through a two-step cation-exchange method, leading to strong combination with active Co2+ sites and utmost utilization efficiencies. Moreover, the super-hydrophility of sulfonic acid groups favors the rapid accessibility of organic molecules to the catalyst and accelerates the degradation. Remarkably, COF-Co exhibits high activity in PMS activation, effective oxidation for tetracycline degradation (92% within 30 min at 30 mg L-1) and other coloring contaminants, and excellent recycle stability. This work can guide the rational design of efficient and environmentally friendly PMS-activated catalyst with great potential for application in wastewater treatment.
