Nanoparticles based Surface Plasmon Enhanced Photocatalysis
Surface plasmonic resonance (SPR)-centered photocatalysts have helped to improve photocatalytic effectiveness for energy- and environmental-related applications, such as wastewater treatment and water splitting. The SPR phenomenon has been well studied in noble metal-based nanoparticles, such as Ag and Au, to achieve an efficient photocatalytic process, particularly for wastewater treatment. SPR-based nanostructures may involve plasmon-facilitated photocatalytic reaction mechanisms, such as Schottky junctions, through electron transfer, improved limited electric fields, and plasmon resonance-based energy transference. This chapter reviews the various factors that are involved in the photodegradation of dyes. A discussion on future directions within this field of investigation is also provided.
