Contrasting mechanistic models for role of photocatalytic support in coupling reactions: (a) electron excited from the valence band (VB) to the conduction band (CB) of the support, creating a hole/electron pair, with electron transfer to the Fermi energy (E_f) of the nanoparticle; (b) plasmonic resonance resulting in “hot electron” injection into the support CB, where reduction can subsequently occur.
