Schottky Barrier and Surface Plasmonic Resonance Phenomena Towards the Photocatalytic Reaction: Study of Their Mechanisms to Enhance Photocatalytic Activity

Metals are doped on semiconductors to enhance the activity of photocatalysts and two possible phenomena can happen at the interfaces of the semiconductors: Schottky barrier formation and Surface Plasmonic Resonance (SPR). Schottky barriers can improve the photoactivity of a reaction by trapping and...
