Enhancing pseudocapacitive properties of cobalt oxide hierarchical nanostructures via iron doping.

Through co-precipitation and post-heat processing, nanostructured Fe-doped CoO nanoparticles (NPs) were developed. Using the SEM, XRD, BET, FTIR, TGA/DTA, UV-Vis, and techniques were examined. The XRD analysis presented that CoO and CoO nanoparticles that had been doped with 0.

Ag doped CoO nanoparticles for high-performance supercapacitor application.

Ag doped CoO nanoparticles (NPs) were synthesized via a co-precipitation method changing the concentration of Ag. The crystal structure, morphology, surface area, functional group, optical band gap, and thermal property were investigated by XRD, SEM, BET, FTIR, UV-Vis, and TGA/DTA techniques. The XRD results showed the formation of single-cubic CoO nanostructured materials with an average crystal size of 19.

Engineering nanostructured Ag doped α-MnO electrocatalyst for highly efficient rechargeable zinc-air batteries.

Engineering of highly active, and non-precious electrocatalysts are vital to enhance the air-electrodes of rechargeable zinc-air batteries (ZABs). We report a facile co-precipitation technique to develop Ag doped α-MnO nanoparticles (NPs) and investigate their application as cathode materials for ZABs. The electrochemical and physical characteristics of α-MnO and Ag doped α-MnO NPs were compared and examined via CP, CV, TGA/DTA, FT-IR, EIS, and XRD analysis.
