Solid state synthesis of a RuNiO₃ perovskite nanomaterial as an electro-catalyst for direct alcohol (ethanol, methanol and ethylene glycol) fuel cell applications

Abstract

Direct alcohol fuel cells (DAFC) are considered as reliable, clean and sustainable energy conversion technology. However, most of them are reported using noble metals based electro-catalysts such as platinum (Pt),...

Composite electrodes with superior catalytic activity in methanol electro-oxidation fabricated using ternary NiO–CuO–ZnO mixed metal oxides

“…28 Additionally, the synergistic combination of binary and ternary TMOs and TMDCs has been studied to enhance the kinetic efficiency and stability of electrocatalytic electrodes used in fuel cells. 21,29 Due to their physical and chemical characteristics, like a better surface-volume ratio, structural features, increased specific capacitance, durability, stability, nontoxicity, and electrocatalytic behavior, Ni, Cu, and Zn oxides are broadly utilized in photoelectrochemical water splitting, sensors, 30,31 batteries, 5 supercapacitors, 32 solar cells, 33 and optoelectronic applications. 34 The use of mixed metal oxides in the MOR has attracted significant attention due to their synergistic effects.…”

Facile Synthesis of Fiber‐Reinforced Catalyst for High Performance Ethanol and 2‐Propanol Oxidation

“…[ 7 ] In alcohol oxidation reactions (AOR), the metals Pt and Pd in the upper part of the volcano curve are often used for this purpose. [ 8 ] The result of this research provide promising methods for the development of alcohol fuel cells. However, many problems still need to be solved.…”

Nitrogen-doped graphene quantum dots as a support for Ni–Au nanoparticles: efficient electrocatalysts for ethanol and formate fuel cells using hydrogen peroxide as an oxidant

“…4,5 Due to the problems of H 2 as a fuel in proton-exchange membrane fuel cells (PEMFCs), such as its transportation and storage, in recent years, researchers have focused on direct liquid fuel cells (DLFCs). Different liquid fuels can be used in DLFCs, 6 such as ethanol, [7][8][9] methanol, [10][11][12] borohydride, 13,14 hydrazine, [15][16][17] and formate. 18,19 Ethanol oxidation has more steps than the methanol oxidation reaction.…”
