Cover Feature: Visible‐Light‐Driven Plasmonic Photocatalysis Enhanced by Charge Accumulation (ChemNanoMat 8/2019)

Plasmon-induced charge separation (PICS) has been applied to photocatalysis, photovoltaics, chemical sensing, and so on. Photoelectrodes based on PICS were developed by inserting plasmonic gold nanoparticles to the interface between n-type semiconductor TiO2 and p-type semiconductor Ni(OH)2 or CrOx, so that electrons and holes are injected into the former and the latter, respectively. Those p-type materials accumulate positive charges and enhance multi-electron oxidations. The positive charges accumulated under illumination can also be used for driving oxidation reactions after dark.
