Structure and еlectrocatalytic ability of Sn–Ni alloy powders prepared by direct and pulse electrodeposition

Morphology and Structure of Electrolytically Synthesized Tin Dendritic Nanostructures

“…Sn and Sn alloys in the powder form can be obtained by electrolysis from the aqueous [9,10,[14][15][16][17][18][19][20][21][22] and non-aqueous electrolytes [23,24], deep eutectic solvent (DES) [2,11,[25][26][27] and ionic liquids [28][29][30][31]. Various acidic and alkaline aqueous electrolytes, such as chloride [16], chloride-gluconate [14,15], sulfate-coumarin [10], chloride-citrate [16], chloridesulfate-gluconate [15], sulfate [17][18][19][20] and hydroxide [9] electrolytes are used for a production of tin powders of different surface morphology.…”

Ethanol Electrooxidation on Nickel Foam Arrayed with Templated PdSn; From Catalyst Fabrication to Electrooxidation Dominance Route

“…The cubic crystal system of Ni substrate is proved by high intense peaks at 44.83°, 52.25°, and 77.02° angles correspond to (111), (002), and (022) planes according to the reference code of 96‐901‐1604. Additionally, the diffraction peaks at 19.12°, 45.12°, and 65.73° verify (111), (004), and (044) planes of the cubic crystal systems of Ni 2 SiO 4 on the report of 96‐900‐0731 reference code [50] . The confirmation of (001), (002), (110), and (111) planes of tetragonal crystal system of PdO is provided by appearance of diffraction peaks located at 17.04°, 34.47°, 42.58°, and 46.18° according reference code of 96‐101‐1330 [51] .…”

“…In order to explore dominance route of EOR and the role of acetaldehyde in the poisoning phenomena, acetaldehyde oxidation reaction (AOR) was also studied through electrochemical methods on the surface of the designed catalysts. [50] The confirmation of (001), (002), (110), and (111) planes of tetragonal crystal system of PdO is provided by appearance of diffraction peaks located at 17.04°, 34.47°, 42.58°, and 46.18°according reference code of 96-101-1330. [51] The reference code of 96-720-6471 predicts (013) and (031) planes of tetragonal crystal system of SnO with the diffraction peaks at 2θ values of 61.71°and 76.73°.…”

A high-performance Pt-based catalyst for the methanol oxidation reaction: effect of electrodeposition mode and cocatalyst on electrocatalytic activity

“…Alteration of the pulse mode parameters makes an optimal structure with a high active surface area. 40,41 The studies have proved that pulse electrodeposition methods produce smaller and more compact metallic nanoparticles with appropriate morphology and orientation, whereas effective parameters, such as on-time, off-time, duty cycles, and the value of pulse steps, are wisely extracted. 35,37,42 On the basis of the above discussion, we use a pulseelectrodeposition approach for designing of a polymeric substrate with a Pt-based catalyst and employ this catalyst for the MOR in alkaline media.…”
