Effect of sAuNT water on the efficiency of the oxygen evolution reaction (OER) at a Co-Pi@ZnFe2O4@α-Fe2O3:Ti photoelectrode in 1 N NaOH.
(a) Photocurrent density-potential (J–V) curves and (b) efficiencies of the hematite photoelectrodes in DI and sAuNT water electrolytes. The illumination conditions were AM 1.5 G and 100 mW cm−2. Dark current was recorded in DI water in a dark atmosphere.
