Tuning the electronic structure of platinum nanocrystals towards high efficient ethanol oxidation

Electrooxidation behavior of ethanol toward carbon microbead-encapsulated ZnO particles derived from coffee waste

“…Fuel cells allow the direct conversion of the chemical energy contained in the hydrogenenriched fuel and an oxidant into electrical energy through electrochemical oxidation with minimum power losses. Among the various types of fuel cells, direct alcohol fuel cells are promising options due to some unique characteristics such as low permeability in the proton exchange membrane (PEM), along with high energy and power densities [7]. However, compared to direct methanol fuels (DMFCs), direct ethanol fuel cells (DEFCs) have been considered a more appealing candidate due to higher energy density, lower toxicity, volatility, and crossover rate [8].…”

Multiple strategies of porous tetrametallene for efficient ethanol electrooxidation

“…[7][8][9][10] So far, Pt-and Pd-based materials have proven to be the most effective catalysts for the EOR. [11][12][13][14][15] Pd-based materials, as a novel candidate catalyst for various electrocatalytic reactions, are cheap compared to Pt-based materials, relatively abundant reserves, and have better performance than Pt-based electrocatalysts under alkaline conditions. [16][17][18][19] Meanwhile, there is a great interest in Pd-based alloys as an alternative catalyst for the alkaline EOR.…”

Controllable synthesis of platinum–tin intermetallic nanoparticles with high electrocatalytic performance for ethanol oxidation

“…are regarded as the most prominent nanoelectrocatalysts for the EOR or methanol oxidation reaction (MOR). [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] For example, CO, CO 2 , and acetic acid (CH 3 COOH) could be observed at lower potentials, which indicates that the Pt 3 Sn alloy, in contrast with commercial Pt/C, has a negative onset potential shift of 100 mV for the EOR. 3,24 This is due to its higher ability to cleave the C-C bond at low overpotentials and reduced binding energy for CO so as to avoid its poison.…”
