Area of Science:

  • Materials Science
  • Photocatalysis
  • Renewable Energy

Background:

  • Graphitic carbon nitride (g-C3N4) is a promising material for photocatalytic hydrogen evolution.
  • Optimizing its microstructure and parameters is crucial for efficient energy conversion.
  • Addressing the energy crisis and environmental pollution requires advanced photocatalysts.

Purpose of the Study:

  • To design and synthesize a novel nitrogen-defective and sulfur-doped g-C3N4 (S-g-C3N4-D).
  • To investigate its structural, physical, and chemical properties for photocatalytic hydrogen evolution.
  • To elucidate the mechanism of enhanced performance using experimental and theoretical methods.

Main Methods:

  • Synthesis of nitrogen-defective and sulfur-doped g-C3N4.
  • Physical and chemical characterization (morphology, porosity, surface area, light utilization, carrier dynamics).
  • First-principle density functional theory (DFT) calculations for Gibbs free energy of hydrogen adsorption and heterojunction analysis.

Main Results:

  • S-g-C3N4-D exhibits 2D lamellar morphology, high porosity, and large specific surface area.
  • Efficient light utilization and enhanced charge carrier separation and transfer were observed.
  • Calculated optimal Gibbs free energy of adsorbed hydrogen (ΔGH*) is ≈0.24 eV, indicating excellent catalytic activity.
  • A high H2 evolution rate of 5651.5 µmol g⁻¹ h⁻¹ was achieved.
  • A step-scheme heterojunction between S-doped and N-defective domains was identified.

Conclusions:

  • The designed S-g-C3N4-D material demonstrates superior performance in photocatalytic hydrogen evolution.
  • The synergistic effects of nitrogen defects and sulfur doping, along with the formed heterojunction, are key to its high efficiency.
  • This study provides valuable insights for designing high-performance g-C3N4-based photocatalysts.
