IR-Coupled Carbon Nitride Nanosheets

≈40× H₂ Evolution

Couples infrared irradiation with lattice vibrations to activate the n→π* electronic transition, markedly prolonging the lifetime of photocatalytically active charges for highly efficient visible-light water splitting.

Advantages

Two prominent vibration modes at 219 and 737 cm⁻¹ promote corrugation of tri-s-triazine units and induce n→π* transition

fs-TAS confirms n→π* transition prolongs lifetime of shallow electron trapping states and charge separation states
