The interfacial ZnFe2O4 is formed during the slow deposition of Fe3+ at the surface of ZnO.
The electrochemical analysis revealed the p-type nature of surface ZnFe2O4 and Fe2O3.
The interfacial ZnFe2O4 not only facilitate the separation but also act as an individual photocatalyst.
Both, superoxide anion and hydroxyl (HOes/rad" src="/sd/grey_pxl.gif" class="glyphImg imgLazyJSB">) radicals, contribute in the degradation/mineralization process.
