Electrochemically assisted photocatalysis. The role of the photocatalyst is played by a photoelectrode, often a semiconductor.
Note: In photoelectrocatalytic transformations it is possible to identify an electrode and an electrolyte combination in the system along with an explicit, generally macroscopic, electrical circuit for the charge transfer and/or for applying an additional electric potential to the system. This is not so in photocatalysis by colloids or fine dispersions of semiconductors.
