Nitrogen-Doped Carbon Nanosheets for Efficient Degradation of Bisphenol a by H2o2 Activation at Neutral Ph Values

•Nitrogen-doped carbon nanosheets were prepared via a facile two-step thermal annealing method.•The prepared nitrogen-doped carbon nanosheets exhibited efficiently catalytic activity of H2O2 for the removal of bisphenol A from water.•Singlet oxygen (1O2), and superoxide radical (·O2–) served as primary active species for bisphenol A degradation.•Ketonic CO, unsaturated carbon bonds of CC and CC, and graphic C/N are supposed to be active sites for the catalytic process.
