Abstract The broadband light‐absorption ability of carbon dots (CDs) has inspired their application in photocatalysis, however this been impeded by poor electron transfer inside the CDs. Herein, we report preparation Cu–N‐doped CDs (Cu‐CDs) and investigate both doping‐promoted performance photooxidation reactions. Cu–N doping was achieved through a one‐step pyrolytic synthesis with Na 2 [Cu(EDTA)] as precursor. As confirmed ESR, FTIR, X‐ray photoelectron spectroscopies, Cu species chelates...
Graphene-like two-dimensional carbon nanosheets with properly modulated compositions and porosity are of particular importance for robust capacitance harvesting. Nevertheless, the large-scale cost-effective production such nanostructures still remains a great challenge.
