The transformation of waste sludge from municipal wastewater treatment plants into valuable resources is fraught with challenges due to its complex composition. The proposed approach efficiently upcycles trace redox-reactive transition metals present in sludge into single-atom catalysts, offering a dual benefit of effective sludge disposal and enhanced water purification.

市政污水处理厂产生的剩余污泥因成分复杂，将其转化为高价值资源的过程往往面临诸多挑战。本研究提出的方法可将污泥中痕量氧化还原活性过渡金属高效升级制备为单原子催化剂（single-atom catalysts），可实现污泥有效处置与强化水质净化的双重效益。
