Fabrication of Zn-Cu-Ni Ternary Oxides in Nanoarrays for Photo-Enhanced Pseudocapacitive Charge Storage.

ABSTRACT: To meet the increasing demands of energy consumption, sustainable energy sources such as solar energy should be better employed to promote electrochemical energy storage. Herein, we fabricated a bifunctional photoelectrode composed of copper foam (CF)-supported zinc-nickel-copper ternary oxides in nanoarrays (CF@ZnCuNiO_x NAs) to promote photo-enhanced pseudocapacitive charge storage. The as-fabricated CF@ZnCuNiO_x NAs have shown both photosensitive and pseudocapacitive characteristics, demonstrating a synergistic effect on efficient solar energy harvest and conversion. As a result, a high areal specific capacitance of 2741 mF cm^-2 (namely 418 μAh cm^-2) under light illumination can be calculated at 5 mA cm^-2, which delivered photo-enhanc
