Characterization of RuO2 nanocrystals deposited on carbon nanotubes by reactive sputtering

Carbon nanotube–chitosan composite electrodes for electrochemical removal of Cu(II) ions

“…Carbon nanotube (CNT) has been proved to be a competitive and promising electrode material for adsorption or electrosorption due to its large surface area, high mechanical strength, remarkable electrical conductivity and high stability [12][13][14][15][16][17][18]. However, the hydrophobicity of CNT limits its application in electrosorption.…”

Supercapacitor behavior of CuO–PAA hybrid films: Effect of PAA concentration

“…According to the charge storage mechanism, the supercapacitors are classified into two types: (i) an electrochemical double layer capacitor (EDLC) that stores the energy non-Faradically by the accumulation of the charges at the electrode-electrolyte interface and (ii) redox capacitor that stores the energy Faradically by battery-type oxidation reduction reactions leading to the pseudocapacitive behavior [3]. Various transition metal oxides, such as RuO 2 , MnO 2 , Co(OH) 2 , Li 2 FeSiO 4 , and V 2 O 5 have been investigated as possible electrode materials for high-power electrochemical pseudocapacitors [4][5][6][7][8].…”

Hydrothermal Synthesis of CuO/RuO2/MWCNT Nanocomposites with Morphological Variants for High Efficient Supercapacitors

“…The improved redox reactions occur at the surface of RuO 2 through a faradaic charge transfer between electrolyte and electrode, which enhances the specific capacitance of the nanocomposites. The presence of RuO 2 on the surface of MWCNTs modifies the structure and morphology of MWCNTs, which also allows improving the electrochemical reactions and improves the efficiency [33]. The tubular structure and the porous morphology of MWCNTs decrease the diffusion resistance and facilitate the transport and anchoring of NPs in the nanocomposites.…”
