Rational design of copper encapsulated within nitrogen-doped carbon core-shell nanosphere for efficiently photocatalytic peroxymonosulfate activation
Copyright © 2021 Elsevier Inc. All rights reserved..
Photocatalysis utilizing solar energy is a promising strategy for mitigating energy crisis and environmental pollution. Exploring a cost-effective, stable, eco-friendly, and efficient photocatalytic system is extremely urgent. Herein, copper encapsulated within nitrogen-doped carbon nanosphere (CuNC) possessing a unique core-shell structure with high catalytic activity was prepared by ion-exchange and pyrolysis using resin as support. The protective carbon shell can prevent the leaching of metal ions and deactivation of the catalyst. Benefiting from the special structure, Cu@NC exhibited excellent activity and durability toward the degradation of tetracycline by the activation of peroxymonosulfate (PMS). The radical trapping experiments and electron spin resonance analyses were applied to elucidate the main reactive species. This work highlights the great potential of Cu@NC core-shell nanosphere as photocatalyst, which provides a new opportunity for the remediation of environmental pollution.
