Hierarchical Multicomponent Electrode with Interlaced Ni(OH)₂ Nanoflakes Wrapped Zinc Cobalt Sulfide Nanotube Arrays for Sustainable High‐Performance Supercapacitors

Abstract

Adv. Energy Mater. 2017, 7, 1701228 In the originally published article, the discussion reported in the first paragraph of Section 2.1. was incorrect. The discussion is corrected to: The NAs of ZnCo2(CO3)1.5(OH)3 precursor (confirmed by X-ray diffraction (XRD) analysis in Figure S8a, Supporting Information) were directly grown on a Ni foam by a facile hydrothermal process (Step I). The precursor, different from the ZnCo2(C2O4)3 produced by using H2C2O4 instead of CO(NH2)2,[26] was obtained from the chemical reactions of Zn2+, Co2+, and CO(NH2)2 with the provided molar ratios (see Experimental Section) under the hydrothermal environment where CO(NH2)2 generates carbonate ions (CO32−) and hydroxyl (OH−) ions via hydrolysis.
