Comparative electrocatalytic oxidation of ethanol, ethylene glycol and glycerol in alkaline medium at Pd-decorated FeCo@Fe/C core-shell nanocatalysts

Shape-controlled electrochemical synthesis of Au nanocrystals in reline: control conditions and electrocatalytic oxidation of ethylene glycol

“…7a). Moreover, this value is much higher than the irregular Au NCs (2.33), commercial Au electrode (2.16) and previously reported catalysts (Table 1), 7,[51][52][53][54][55][56] showing that the Au NSs have better poisoning-resistant ability and steady-state behaviour for EG oxidation. Fig.…”

“…3,4 The electrooxidation of alcohols has come to be of signicant interests because of its potential application in direct alcohol fuel cells (DAFCs) over the past few years. [5][6][7] To date, tremendous efforts have been made to investigate the electrooxidation of alcohols including methanol, ethanol, ethylene glycol (EG), propanol and glycerol. [8][9][10][11] Among alcohol fuels, methanol has been the most widely studied.…”

Electro-oxidation of ethylene glycol and glycerol at palladium-decorated FeCo@Fe core–shell nanocatalysts for alkaline direct alcohol fuel cells: functionalized MWCNT supports and impact on product selectivity

“…[33][34][35] In the present study, MWCNT-COOH and MWCNT-SO 3 H are used as supports rather than the Vulcan XC-72. First, FeCo@Fe/MWCNT-COOH and FeCo@Fe/MWCNT-SO 3 H core-shell nanoalloys were obtained by a simple reduction method via hydrogenation.…”

“…Recently, we introduced Pd-based ternary core-shell with a bimetallic (FeCo) core supported on commercial Vulcan carbon XC-72 (i.e., FeCo@Fe@Pd/C) via "microwave-induced top-down nanostructuring and decoration" (MITNAD) strategy. [33][34][35] The MITNAD strategy is simply the adoption of fast microwave irradiation for a one-step top-down nanosizing of large-sized soft magnetic FeCo@Fe/C core-shell material (0.21-1.5 microns) to sub-10 nm sized Pd-coated structure, FeCo@Fe@Pd/C. In the present work, we have interrogated the use of two differently chemically-functionalized multi-walled carbon nanotubes (MWCNTs) bearing mainly the -COOH or -SO 3 H surface groups (abbreviated herein as MWCNT-COOH and MWCNT-SO 3 H, respectively), as supporting platforms for the FeCo@Fe@Pd catalyst.…”

Ethylene glycol oxidation on ternary PtRhNi/C electrocatalyst with different metal compositions

“…Thus, alkaline direct alcohol fuel cells (ADAFC's) have some advantages such as low-emission, high energy efficiency (9,10), improved oxidation kinetics, low crossover and in addition there is a broad range of materials that can be used as catalysts [8,11,12]. Between the possible alcohols, ethylene glycol (EG) has received attention in recent decades as an alternative fuel for ADAFC because of its high theoretical energy density of 5.2 kWhKg -1 , easy storage and non-toxicity, beside to be abundant and originated from renewable source, such as cellulose [2,3,4,9,10,13,16,17]. For the other hand, in fuel cells powered by direct liquid alcohol, the fuel must be completely oxidized (or close to 100%) to generate great power, but this still is a difficult task in ADAFC and for solve this problem researchers in different parts of the world are developing new catalysts for the full oxidation of ethylene glycol [3].…”
