Design of Co-Sn bimetallic nanoalloys as electrocatalyst for alkaline methanol oxidation reaction: Exploring the effect of electroactivation process

Electrodeposition of nickel–cobalt alloys from metal chloride-l-serine deep eutectic solvent for the hydrogen evolution reaction

“…43 For Co, the small redox peaks at 1.35 and 1.46 V RHE , and 1.10 and 1.24 V RHE represent the oxidation of Co(OH) 2 /Co(O)OH and Co(O)OH/CoO 2 redox processes, respectively. 44 The redox peaks are less obvious, which indicates that the Co prepared using this electrodeposition method generates a smaller number of active sites. For Ni–Co, apparent redox peaks are at 1.38 V RHE (anodic) and 1.17 V RHE (cathodic).…”

The Tunable and Efficient Nanoporous CuAg Alloy Catalysts Toward Methanol Oxidation Reaction Synthesized by Electrochemical Dealloying of Metallic Glassy Precursors

“…Figure 7b shows the CV curves of the NPCu 1.75 Ag catalyst in 1 M KOH with and without 1 M methanol solution at a scan rate of 50 mV s −1 . It is found that the current density shows a rapid increase at potential above 0.67 V in the presence of methanol and reaches to a super‐high value of 397.2 mA cm −2 at 1 V. The electrochemical oxidation of the methanol on the NPCu 1.75 Ag surface can be described by the following reaction [Equations , , , , , ]: [5a,18,20c,23] $$$\vcenter{\openup.5em\halign{$\displaystyle{#}$\cr {\rm M}+{\rm OH}{^{- }}\rightarrow {\rm M}\hbox{-}({\rm OH}){_{{\rm ad}}}+{\rm e}{^{- }}\hfill\cr}}$$$ $$$\vcenter{\openup.5em\halign{$\displaystyle{#}$\cr {\rm M}\hbox{-}({\rm OH}){_{{\rm ad}}}+{\rm CH}{_{3}}{\rm OH}\rightarrow {\rm M}+{\rm CH}{_{3}}{\rm O}{_{{\rm ad}}}+{\rm H}{_{2}}{\rm O}\hfill\cr}}$$$ $$$\vcenter{\openup.5em\halign{$\displaystyle{#}$\cr {\rm M}\hbox{-}({\rm OH}){_{{\rm ad}}}+{\rm CH}{_{3}}{\rm O}{_{{\rm ad}}}\rightarrow {\rm M}+{\rm CH}{_{2}}{\rm O}{_{{\rm ad}}}+{\rm H}{_{2}}{\rm O}\hfill\cr}}$$$ …”
