Introducing oxophilic metal and interstitial hydrogen into the Pd lattice to boost electrochemical performance for alkaline ethanol oxidation

Abstract

The sluggish kinetics of ethanol oxidation reaction (EOR), poor C1 selectivity and susceptibility to toxicity of CO intermediates hinder the commercialization of direct ethanol fuel cells (DEFCs). In this paper,...

NiCoPd Inlaid NiCo-Bimetallene for Efficient Electrocatalytic Methanol Oxidation

“…The determining Coulombic charge (Q) corresponds to the reduction peak of palladium oxide in CV curves of the sample in 0.5 M KOH solution . A charge value of 405 μC/cm 2 is assumed for the reduction of the PdO monolayer …”

“…47 A charge value of 405 μC/cm 2 is assumed for the reduction of the PdO monolayer. 48 In the process of aging treatment, the influencing factors of EASA depend on the morphology of 2D structure of NiCobimetallene and alloying degree of NiCoPd. As expected, the calculation results of EASA based on Figure S5 show that the maximum EASA value (185.2 m 2 /g Pd) can be obtained by the atom-diffusion-aging treatment under 150 °C for 48 h, which is corresponding to the conditions for the optimal mass activity (Table 1).…”

Recent Advances in Anode Electrocatalysts for Direct Formic Acid Fuel Cells – Part I – Fundamentals and Pd Based Catalysts

“…According to Gao et al, the improved catalytic activity for the carbon supported PdNi (3 : 1) was due to the formation Nickle, and cobalt well known oxophilic metals. [148] Due to the oxophilic nature, Ni easily gets converted into NiO. XPS studies confirm that catalysts contained Ni partly as NiO and rest as NiPd alloy.…”

“…According to Gao et al., the improved catalytic activity for the carbon supported PdNi (3 : 1) was due to the formation of small and well dispersed Pd nanoparticles, oxophilic nature of Ni which can generate oxygen containing species, electronic structure modifications due to the PdNi alloy formation. Nickle, and cobalt well known oxophilic metals [148] . Due to the oxophilic nature, Ni easily gets converted into NiO.…”

Ultrahigh stable covalent organic framework-derived carbon–nitrogen-supported palladium nanoparticles for highly efficient electrocatalytic methanol and ethanol oxidation reactions

“…A carbon monoxide stripping voltammetry test is usually used to judge the CO tolerance of the catalyst. [44][45][46] As shown in Fig. 7(b-d), in the forward scan of the first round of the CO stripping cycle, the hydrogen zone disappeared because CO was adsorbed on the Pd-based catalyst.…”
