High electrochemical performance of nickel cobaltite@biomass carbon composite (NiCoO@BC) derived from the bark of for supercapacitor application.

Biomass carbon-based materials are highly promising for supercapacitor (SC) electrodes due to their availability, environment-friendliness, and low cost. Herein, an easy energy-saving hydrothermal process was used to produce NiCoO/NiOOH (NiCoO) composites with biomass carbon (BC) derived from the bark of (AO) at different synthesis time durations (2 h, 4 h, 8 h, 16 h). The structural and morphological properties of the samples were analysed using XRD, Raman spectroscopy, XPS, SEM, TEM and BET, and the results exhibit the presence of carbon inserted into the nickel-cobalt hydroxide matrix.
