Plasmonic metal/semiconductor hetero-nanostructures have attracted tremendous research interests in optoelectronic devices, photocatalysis and photothermal therapy, related fields. Among various mechanisms of localized surface plasmon resonance (LSPR) induced enhancements, the mechanism LSPR-induced hot carrier injection has emerged as a particularly powerful efficient process for modulating charge dynamics, especially photocatalysis. The efficiency these injections relies on robust metal–semiconductor interfaces, with performance heavily influenced by composition, crystallinity, atomic structure multi-interfaces involved. This letter explores injection, highlighting recent advances emphasis multi-interfacial engineering to optimize dynamics utilization. These interface-regulated processes, combined enhanced photocatalytic performance, provide new opportunities further advanced wide range photoelectric conversion applications.

Constructing patterned film photoanodes with economizing raw chemicals but enhancing photoelectrochemical (PEC) performance is attractive for practical applications. However, simultaneously optimizing light scattering and interfacial charge transfer through plasmonic enhancement remains challenging. Herein, we developed a novel photoanode featuring Au grids nanometer-thick CdSe layer (Au grid-CdSe) well-organized heterointerfaces, fabricated via facile colloidal topochemical strategy. This design leverages the synergistic coupling between plasmons excitons in heteropatterned films. The underlying serve dual functions: as an electron collector reflector. Their highly ordered Bragg structure effectively scatters incident into ultrathin layer. Furthermore, CdCl2 surface passivation of Au(grid)-CdSe photoanode, based on this unique absorption/reflector architecture, yielded photocurrent density 4.51 mA cm-2, representing significant enhancement. Compared to similarly prepared Au-CdSe heterofilms, passivated films exhibited 2.0-fold higher PEC hydrogen evolution performance, maintained excellent stability over 26 h, reduced consumption by 32%. strategy offers pathway improving semiconductor-based optoelectronic devices.
