Опубликована: Май 16, 2023

Although challenges remain, synergistic adjusting various microstructures and photo/electrochemical parameters of graphitic carbon nitride (g-C3 N4 ) in photocatalytic hydrogen evolution reaction (HER) are the keys to alleviating energy crisis environmental pollution. In this work, a novel nitrogen-defective sulfur-doped g-C3 (S-g-C3 -D) is designed elaborately. Subsequent physical chemical characterization proved that developed S-g-C3 -D not only displays well-defined 2D lamellar morphology with large porosity high specific surface area but also has an efficient light utilization carriers-separation transfer. Moreover, calculated optimal Gibbs free adsorbed (ΔGH* for at S active sites close zero (≈0.24 eV) on basis first-principle density functional theory (DFT). Accordingly, catalyst shows H2 rate 5651.5 µmol g-1 h-1 . Both DFT calculations experimental results reveal memorable defective /S-doped step-scheme heterojunction constructed between S-doped domains N-defective structural configuration -D. This work exhibits significant guidance design fabrication high-efficiency photocatalysts.
