Plasmon-enhanced photocatalysis represents a promising avenue due to its potential to harness solar energy more efficiently. This technology typically involves the use of plasmonic nanoparticles such as gold (Au) and silver (Ag), coupled with semiconductor materials such as TiO2 to enhance light absorption and catalytic efficiency. When coupled with plasmonic nanoparticles, TiO2 can benefit from enhanced light absorption and improved charge carrier generation, separation and utilization, leading to increased photocatalytic efficiency. The localized surface plasmon resonance (LSPR) of these metal nanoparticles results in enhanced electromagnetic fields that can be harnessed to drive photocatalytic reactions. , However, despite this progress, the efficiency of plasmon-enhanced photocatalysis is often refrained by the limited extent of interaction between the plasmonic nanoparticles and the semiconductor.
