Abstract

Au TNP/g-C₃N₄ as a plasmonic photocatalyst for H₂ production under NIR light irradiation was investigated by finite-difference time-domain (FDTD) simulations and time-resolved transient absorption measurements, revealing enhanced H₂ production owing to a stronger electromagnetic field in Au TNP/g-C₃N₄ and plasmon-induced hot electron transfer from Au TNPs to g-C₃N₄.
