摘要: Abstract This paper reports the synthesis of lanthanum oxide/hydroxide nanoparticle (LaNPs)-doped rGO nanosheets. The uniform distribution LaNPs on nanosheets was confirmed by FESEM, TEM, and elemental analysis. A dramatic change in electrochemical behavior observed adjusting concentration (LaG ratio = 1:2, 1:1 2:1). LaG 12 showed a better areal capacitance 889.29 F cm−2 than 11 (428.58 F cm−2) 21 (260.72 F cm−2). Further, improved cycle stability (84% after 1000 cycles) with good impedance confirms is suitable electrode material for high-performance supercapacitor fabrication.
