The role of the photocatalyst is played by a photoelectrode, often a semiconductor.","notes":{"1":"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."},"links":[{"term":"photoelectrode","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/14051"}],"sources":["PAC, 2011, 83, 931.
