Abstract

We have used gold nanostructures to excite various plasmonic modes such as multi-scattering, hot electron injection (HEI) and plasmon-induced resonant energy transfer (PIRET). Together they enable to enhance the utilization of solar light for photocatalytic processes. Detailed experimental and mechanism studies have been conducted to examine the plasmonic enhancement in photocurrent, photodegradation and total water splitting. Our work may find potential applications in optical redox-based sensors and green energy.
