DOI: 10.1016/j.jelechem.2018.05.003

Abstract: Abstract A modified activated carbon material for supercapacitors is prepared via the treatment of gulfweed–based activated carbon with hydrofluoric and nitric acid. The properties of the carbons are characterized by nitrogen adsorption–desorption, scanning electron microscope… read more here.
