Abstract:
The light absorbing property and the availability of catalytically active sites make plasmonic nanostructures ideal candidate for the enhancement in photocatalysis rate. Plasmonic nanostructures can concentrate otherwise diffused visible illumination of photons to drive chemical transformations. This also results into introduction of different pathways to control the selectivity of the reactions. Here, fundamental photophysics in chemical reactions driven by localized surface plasmon resonance (LSPR) have been discussed. Some of the selected notable works on plasmon mediated direct plasmon catalysis achieved so far have been reviewed. Variation in the rate of photocatalysis due to the variation in illumination intensity and photon energy has been discussed in terms of the mechanisms of photocatalysis. Though there are a lot more work needed to confirm the selectivity in plasmonic photocatalysis, the evidence of the role of plasmon nanostructures in enhancing the rate of photocatalytic reactions can be obtained from both intensity and wavelength dependent rate of catalysis, thereby giving an alternative to the conventional thermally mediated heterogeneous catalysis.
