Manganese oxide nanoparticles prepared by olive leaf extract-mediated wet chemistry and their supercapacitor properties

Green supercapacitors: review and perspectives on sustainable template-free synthesis of metal and metal oxide nanoparticles

“…Manganese oxide (Mn 3 O 4 ) is another prominent supercapacitor electrode material prepared from olive leaf extract with Na 2 SO 4 as the electrolyte, exhibiting a specific capacitance of 583.7 F g −1 . 122 RuO 2 is regarded as one of the most promising SC electrodes because of its high theoretical specific capacitance (1700 F g −1 ), strong electric conductivity (105 S cm −1 ), and reversible redox reaction. Additionally, RuO 2 has broad applicability in aqueous systems with various aqueous electrolytes because of its strong corrosion resistance to acidic and basic conditions.…”

Phyto-inspired Cu/Bi oxide-based nanocomposites: synthesis, characterization, and energy relevant investigation

“…In addition, the storage of renewable forms of energy in different devices, especially supercapacitors, has been highly studied due to their efficient output and performance. 4,5 Hydrogen represents one of the most abundant elements that is present on earth, in the form of water, hydrocarbons, and carbohydrates. The combustion of hydrogen leads to the production of water and for this reason it is deemed a future candidate for energy production characterized by efficiency and cheaper costs.…”
