Nano CeO2/activated carbon based composite electrodes for high performance supercapacitor

The development supercapacitor from activated carbon by electroless plating—A review

“…The EDLC, generally focusing on carbon materials, which arising from the charge separation at the electrode/electrolyte interface, whereas faradic supercapacitor materials, such as cerium oxide [15], titanium oxide [8], vanadium oxide [53], cobalt oxides [5,[54][55][56], nickel oxide [9,54], manganese oxide [10,11,57,58], indium oxide [59], bismuth oxide [60], tin oxide [59] and ruthenium oxide [61][62][63][64][65], which not only store energy like an EDLC, but also display electrochemical faradic reactions between ions and electrode materials in the suitable potential window. To develop ECs performance, especially its specific energy while retaining its basic high specific power, many researchers have focused their efforts mostly on improving the properties of electrode materials.…”

“…Recently the researches have been also focused on the advance of an alternate class of supercapacitors based on fast reversible Faradaic reactions. Generally, identified as "pseudocapacitors" they consist of various transition oxides [3][4][5][6][7][8][9][10][11][12][13][14][15][16], transition metal nitrides [17], and conducting polymers [18][19][20][21]. The surface functional groups changes the electrochemical performance (such as capacitance, electrical conductivity, and selfdischarge) of carbon materials in two different ways.…”

Effect of hybridization on the value-added activated carbon materials

“…species on the surface. The use of AC as a support structure also favors the removal of both organic compounds [148,149]. Recent studies have focused on the catalytic activity of CeO 2 in ozonation reactions and investigated a possible synergistic effect between AC and CeO 2 in the ozonation of organic compounds [150].…”

Graphite nanosheets/nanoporous carbon black/cerium oxide nanoparticles as an electrode material for electrochemical capacitors

“…Different morphologies have been reported for carbon base materials; for example, carbon blacks (CBs), CNTs and graphene nanosheets exhibit spherical, tubular and lamellar structures, respectively. On the other hand, oxides and hydroxides of transition metals like Ru [18], Co [19], Zr [20], Mn [21] and Ce [22], and conducting polymers, like polyaniline (PANI) [23] and polypyrrole [24] are of candidate materials for supercapacitors which store energy through pseudo mechanism. These materials possess multiple oxidation states that enable rich redox and Faradic reactions on surface of carbon base materials.…”
