Electrocatalytic activity of bimetallic Pd–Ni thin films towards the oxidation of methanol and ethanol

Recent Development of Pd-Based Electrocatalysts for Proton Exchange Membrane Fuel Cells

“…Qiu et al [156] prepared bimetallic Pd-Ni thin film on glass carbon electrodes (GCEs). The high catalytic activity and the low cost of the Pd-Ni films enable them to be promising catalyst for the oxidation of methanol and ethanol in alkaline media.…”

Enhanced methanol oxidation and oxygen reduction reactions on palladium-decorated FeCo@Fe/C core–shell nanocatalysts in alkaline medium

“…The ratio of the forward anodic peak current density (I f ) to the reverse anodic peak current density (I b ) i.e., (I f /I b ) is indicative of the ability of the catalyst to tolerate the accumulation of carbonaceous species. [39][40][41][42][43] The I f /I b ratios were estimated as 4.2 and 2.7 for FeCo@Fe@Pd/C and Pd/C, respectively, indicating excellent MOR on the core-shell platform. EIS experiments were performed at À0.2 V to provide further insights into the activities of the two catalysts (Fig.…”

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

“…Nevertheless, among the various methods, electrodeposition is recognized as a simple and versatile method to prepare bimetallic surfaces. Several methods for PdNi alloy electrodeposition can be find in the literature such as: doublepotential step electrodeposition technique from the solution containing NiSO 4 , H 2 PdCl 4 and Na 2 SO 4 [23]; cathodic deposition from the solution containing PdCl 2 , H 2 SO 4 , NH 4 Cl and NiCl 2 using hydrogen dynamic bubble template producing three-dimensional hierarchical pores of intercomnected dendrite walls [ 24 ]; electrodeposition in the presence of complexing agent, ethylenediamine [25,26]; electrodeposition from a ionic liquid as electrolyte [16,27]; physical vapour deposition which was used to obtain palladium-modified nickel foam material [19].…”
