Abstract
Upcycling valuable metals from wastewater promises addressing the metal resource recycling and water pollution control issues simultaneously. In particular, upcycling Nickel (Ni) ions into electrocatalytic material has been proven a feasible route, but the current methods are still restricted by the complicated, environmentally-aggressive operation. Herein, we propose a low-cost, 3D-structured adsorbent, constructed by in-situ growing ZIF-8 on network-structured bacterial cellulose, for efficient Ni capture. It exhibits superior stability and 7.3-times higher Ni adsorption kinetics than the ZIF-8 alone. Importantly, the Ni-enriched adsorbent, after treatment of Ni-containing electroplating wastewater, could be pyrolytically converted into an efficient self-supported electrocatalyst for oxygen evolution reaction (OER), showing comparable OER activity to the state-of-the-art Ni-based electrode. This work provides a sustainable, facile route for Ni upcycling into self-supported electrode, which may be extended to recovery of various valuable metals from waste streams. © 2024 Elsevier B.V.
