Electrocatalytic activity of binary and ternary composite films of Pd, MWCNT, and Ni for ethanol electro-oxidation in alkaline solutions

Electrochemical behavior of electrodeposited Pd and PdNi coatings for the ethanol oxidation reaction in alkaline solution

“…The results of the Tafel polarization study corroborate the findings of CV. Nearly the same values of Tafel plots were obtained on graphene supported NiPd binary catalysts [6], binary composite films of Pd and Ni on multiwalled carbon nanotubes (MWCNT) [36], carbon supported PdNi nanoparticles [35,37] and rather higher on PdNi nanoparticles supported on sulfonated MWCNT [38]. Figure 6 shows the CVs obtained at Pd 0.74 Ni 0.26 catalyst in 1 M NaOH +1.0 M C 2 H 5 OH solution at different scan rates.…”

Preparation of Nanostructured Pd-C-Ru Composite Electrodes for Alcohol Electrooxidations. Part-I: A Study of Ethanol Oxidation by Cyclic Voltammetry and Impedance Spectroscopy

“…Binary composites of Pd and 0.5wt% C and Ru and 0.5wt% C and ternary composites of Pd, 0.5wt% C and Ru were prepared by sodium borohydride reduction method as previously described [27]. Ternary composites prepared were those containing 1, 2, 5, 10, 20, 30, and 50wt%Ru.…”

“…Singh et al [27][28][29] obtained nanocomposite films of Pd and MWCNTs and of Pd and nanocarbon (C) for use as electrocatalysts for the EOR [27][28] and MOR [29,30] -2 . The rate of oxidation followed the order glycerol > ethanol > methanol.…”

Development of Inexpensive High Energetic Electrodes Ni-Cu and Ni-CeO2-Cu for Renewable Energy through Direct Ethanol Fuel Cell

“…NiO, CeO 2 , Co 3 O 4 , Mn 3 O 4 [3,[17][18][19]. It is also suggested that an addition of Ni to Pd as Ni(OH) 2 /NiOOH improves the apparent electro catalytic activity of the electrode in ethanol [20]. Nano-coated Ni-based alloys have also been investigated by Paul et al [21,22] for inexpensive fuel cell electrode for energy applications.…”
