The properties of electrochemically generated interfacial palladium particles as novel reductive photocatalysts for liquid I liquid reactions are introduced in the present contribution. The pd particles win prepared at the interface between two immiscible electrolyte solutions (ITIES) by heterogeneously reducing ammonium tetrachloropalladate present in the aqueous phase by the electron donor ferrocene in 1,2-dichloroethane, As-deposited particles are shown to act as electron transfer mediators in the heterogeneous photoreduction of tetracyanoquinodimethane (TCNQ) by hydrophilic porphyrin species.
