The mixed marriage of copper and carbon ring-g-C3N4 nanosheet: A visible-light-driven heterogeneous Fenton-like catalyst

Effective photogenerated charge separation and rapid Cu(II)/Cu(I) redox cycling is still challenging for photocatalytic reactions and copper-based Fenton-like process, respectively. Herein, a novel heterogeneous Fenton-like catalyst of copper incorporated carbon ring-g-C3N4 (Cu-C-CN) was prepared through a facile calcination method. The carbon ring could be intimately connected with g-C3N4 via sp2-hybridized CN bonds to form an in-plane...
