Overview

Demonstrates enhanced hydrogen evolution in graphitic carbon nitride, suggesting significant efficiency improvements.

Key Points

  • To optimize the molecular structure of graphitic carbon nitride for improved hydrogen evolution performance.
  • Enhanced CN’s structure via copolymerization with organic molecules
  • Optimized crystallinity of the photocatalyst to promote charge separation
  • Measured hydrogen evolution rates and apparent quantum efficiency.
  • Achieved a hydrogen evolution rate of 23.13 mmol·h−1·g−1 with CNBM, a 118-fold increase compared to pristine CN
  • Demonstrated an apparent quantum efficiency of 87.9% at 420 nm
  • Improved surface area led to more active sites and effective separation of electron-hole pairs.
