Non-Noble Metal as Catalysts for Alcohol Electro-oxidation Reaction

Foam Synthesis of Nickel/Nickel (II) Hydroxide Nanoflakes Using Double Templates of Surfactant Liquid Crystal and Hydrogen Bubbles: A High-Performance Catalyst for Methanol Electrooxidation in Alkaline Solution

“…Nevertheless, the DMFC suffers from several challenges that limit its performance in commercial markets due to the high price of platinum catalyst and the slow kinetics of the methanol oxidation reaction (MOR) as a result of catalyst surface poisoning [ 1 , 4 , 5 , 6 , 7 ]. Consequently, it is necessary to develop low-cost, non-noble, and efficient transition-metal electrocatalysts to improve electrocatalytic activity and durability for MOR [ 8 , 9 , 10 ].…”

Cost-effective functionalization of Vulcan XC-72 by using the intermittent microwave heating process as nanocatalyst support for ethanol electrooxidation in acid media

“…Meanwhile, the use of carbonaceous conductive materials as support have the purpose of reducing the metal loading and therefore the costs, also having a positive effect in promoting the catalytic activity of fuel cell nanocatalysts (Auer, Freund, Pietsch, & Tacke, 1998;Thompson, Jordan, & Forsyth, 2001). Carbon supports possess high surface area, good electrical conductivity and reasonable porosity (Dessources, del Jesús González-Quijano, & Pech-Rodríguez, 2018;J. Wang et al, 2007).…”

Electrochemical Deposition of Pd@Pd(OH)2 Core-Shell Nanoparticles onto Glassy Carbon from a Deep Eutectic Solvent (Reline) and their Use as Electrocatalyst for the Methanol Oxidation Reaction

“…2 To improve the performance of the DMFC, several types of nanoparticles have been applied as anode catalytic materials toward the MOR in alkaline media, for instance: Pt-based, PtRuIn/C 3 and noble metal-free catalysts: Ni(OH) 2 /GC. 4,5 In particular, the Pdbased ones have exhibited greater tolerance towards poisoning during MOR in alkaline media compared with Pt-based electrocatalysts: Cu x Pd y /C, 6 Pd x Ag y /C, 7 PdFe/MWCNT, 8 PtPdPt/GCE, 9 PdCu/VC, 10 Pd y Cu x /rGO, 11 Pd-GO/CC, 12 PdCu/GCE, 13 and PdCuCo/rGO. 14 The modification of the electrode surfaces with these nanoparticles involves in general two stages, [4][5][6][7][8][10][11][12][13][14] namely, nanoparticles synthesis followed by some procedure for supporting them on the electrode.…”

In this methodology, the synthesis is usually carried out by chemical reduction of the metallic precursor using both, reducing agents (i.e.…”
