(a) Crystal structure of CN, MoS_2, and CN/M of different perspectives after structure optimization; (b) The lattice matching method of MoS₂(4 × 4) and CN($\sqrt{3}$ × $\sqrt{3}$); (c) Adsorption structure of O₂ vertical and horizontal absorption onto CN/M, respectively. Red atoms indicate O atoms; (d) Electronic band gap structure of CN, MoS_2, and CN/M; (e) Electrostatic potential of CN/M; (f) The schematic diagram of the electron transfer process between CN and MoS₂ based on DFT calculation and the synergistic treatment mechanism of CN/M/GOx C-bio-HJs.
