Ultrafast spectroscopic study of plasmon-induced hot electron transfer under NIR excitation in Au triangular nanoprism/g-C3N4 for photocatalytic H2 production.

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.
