“…In this context, the development of a new class of catalysts able to efficaciously convert the methanol and to work as an anode in the DMFC device and, at the same time, to be highly active, to have a low price, and to have good stability is one of the challenges of the scientific community [8][9][10][11][12]. The standard catalyst commonly used for methanol oxidation is platinum (Pt) [13][14][15] but, unfortunately, the Pt catalyst surface is rapidly poisoned leading to a decrease in the catalysts active surface [16,17]. In order to avoid this process, a new class of MOR catalysts has been developed by alloying the Pt with Ru and by a preparation of binary catalysts [18][19][20][21][22].…”

The commercialization of the Direct Methanol Fuel Cell (DMFC) is limited due to the high cost and low efficiency of the electrocatalysts. In this context, the development of new electrocatalysts able to efficiently oxidize the methanol and to have at the same time low price and high stability is one of the researcher’s milestones. In this work, CoPt alloys with different Pt content were prepared, and the efficiency of the alloys to be used as electrocatalysts for the methanol oxidation reaction (MOR) was investigated. Our data show that the electrocatalytic performance of the CoPt electrodeposited alloys is strongly influenced by the synthesis conditions, mainly by the potential applied during the synthesis. The best electrocatalytic activity was obtained for the samples prepared at −0.8 V/SCE.

“…Pt is one of the most commonly used catalysts for fuel cells due to its remarkable electrocatalytic activity. 22–24 To increase the resistance to CO poisoning of Pt, 25 the method of plasmon-enhanced electrooxidation is employed, 26,27 wherein Au is introduced because of its strong plasmonic properties and excellent stability. 28 This proposed CO-stripping strategy is devoted to enabling the in situ differentiation of local reactions that occur on Pt and Au sites and thus can be developed as a general strategy to probe the fundamental mechanisms in metallic heterogeneous plasmonic electrocatalysts.…”

Direct liquid fuel cells (DLFCs) can convert the chemical energy of small organic molecules directly into electrical energy, which is a promising technique and always calls for electrocatalysts with high activity, stability and selectivity. Palladium (Pd)‐based catalysts for DLFCs have been widely studied with the pursuit of ultra‐high performance, however, most of the preparation routes require complex agents, multi‐operation steps, even extreme experimental conditions, which are high‐cost, energy‐consuming, and not conducive to the scalable and sustainable production of catalysts. In this review, the recent progresses on not only the rational design strategies, but also the facile preparation methods of Pd‐based electrocatalysts for small molecules oxidation reaction (SMOR) are comprehensively summarized. Based on the principles of green chemistry in material synthesis, the basic rules of “facile method” have been restricted, and the fabrication processes, perks and drawbacks, as well as practical applications of the “real” facile methods have been highlighted. The landscape of this review is to facilitate the mild preparation of efficient Pd‐based electrocatalysts for SMOR, that is, to achieve a balance between “facile preparation” and “outstanding performance”, thereby to stimulate the huge potential of sustainable nano‐electrocatalysts in various research and industrial fields.
