Conformal Coverage of ZnO Nanowire Arrays by ZnMnO₃ : Room-temperature Photodeposition from Aqueous Solution.

ABSTRACT: Compositionally and structurally complex semiconductor oxide nanostructures gain importance in many energy-related applications. Simple and robust synthesis routes ideally complying with the principles of modern green chemistry are therefore urgently needed. Here we report on the one-step, room-temperature synthesis of a crystalline-amorphous biphasic ternary metal oxide at the ZnO surface using aqueous precursor solutions. More specifically, conformal and porous ZnMnO₃ shells are photodeposited from KMnO₄ solution onto immobilized ZnO nanowires acting not only as the substrate but also as the Zn precursor. This water-based, low temperature process yields ZnMnO₃ /ZnO composite electrodes featuring in 1 M Na₂ SO₄ aqueous solution capaci
