Abstract
Abstract:
Within the current production systems, the need for low environmental impact processes to
produce chemicals, the treatment of aqueous effluents and the production of fuels is becoming an increasingly
urgent challenge. In this context, photoelectrocatalysis (PEC), which couples the electrochemical
method (EC) with photocatalysis (PC), can be considered a valid alternative to traditional
catalytic processes. It increases the photocatalytic and the electrochemical efficiency by improving the
separation of the photoproduced electrons and holes on the active electrode surface and addressing the
partial oxidation products formation by selecting the applied potential values. This review is concerned
with the possibility of forming PEC high-added-value chemicals, sometimes with the contemporary
production of hydrogen, by using different materials for the fabrication of photoanodes and
photocathodes in different solvents and system configuration, obtaining very interesting values of
conversion, selectivity, and Faradaic efficiencies. In particular, the review presents results related to
the production of valuable compounds by the valorisation of alcohols, biomass derivatives and some
peculiar organic substrates, highlighting the influence of electrode composition, applied bias, electrolyte
type, and solvent.
