Growth of Ultrathin Mesoporous Ni-Mo Oxide Nanosheet Arrays on Ni Foam for High-performance Supercapacitor Electrodes

“…EDLCs using carbonaceous materials (such as activated carbon [10], carbon nanotubes [11], graphene [12,13] and carbon aerogels [14]) store energy through the electrostatic adsorption of ions on their surfaces, while pseudocapacitors utilizing the fast reversible Faradaic redox reactions have gained more attention in recent years, due to their substantially higher specific capacitance and energy density with respect to EDLCs [9,15]. Generally, the reported electrode materials for pseudocapacitors are mainly including the conductive polymers (polyaniline [16], polypyrrole [17]), transition metal oxides (NiO [18,19], [20][21][22], MnO 2 [23,24], V 2 O 5 [25]), hydroxides (Ni(OH) 2 [26], Co(OH) 2 [27], NiCoAl-LDH [28][29][30]) and so forth.…”

Effect of microwave power on the thermal genesis of Co3O4 nanoparticles from cobalt oxalate micro-rods

“…Co 3 O 4 has attracted considerable interest owing to its broad applications in various important technological fields such as supercapacitors [5], sensors [4,6] and anode materials in Li ion rechargeable batteries [7][8][9][10][11]. Cobalt oxide based catalysts has been thought to be the active species in a variety of chemical reactions.…”

Electrochemical properties of microwave-assisted reflux-synthesized Mn3O4 nanoparticles in different electrolytes for supercapacitor applications

“…Carbon-based materials are widely used as EDLC electrodes due to their higher surface area [2]. There are various metal oxides synthesized for supercapacitor application such as RuO 2 [3], NiO [4], Co 3 O 4 [5], Bi 2 O 3 [6], SnO 2 [7], and manganese-based oxides [8][9][10]. Among all the transition metal oxides, RuO 2 possesses higher specific capacitance of 720 F g -1 [11].…”
