Investigation of Nanometals (Ni and Sn) in Platinum-Based Ternary Electrocatalysts for Ethanol Electro-oxidation in Membraneless Fuel Cells

Abstract

In the present work, Carbon supported Pt 100 , Pt 80 Sn 20 , Pt 80 Ni 20 and Pt 80 Sn 10 Ni 10 electrocatalysts with different atomic ratios were prepared by ethylene glycol-reduction method to study the electro-oxidation of ethanol in membraneless fuel cell. The electrocatalysts were characterized in terms of structure, morphology and composition by using XRD, TEM and EDX techniques. Transmission electron microscopy measurements revealed a decrease in the mean particle size of the catalysts for the ternary compositions.

Single microfluidic fuel cell with three fuels – formic acid, glucose and microbes: A comparative performance investigation

“…As a result, it was successfully developed as a miniaturized biosensor and power source by utilizing various fluid resources such as domestic and industrial wastewater, urine, and soiled water from sewage [10,11]. In CFCs, chemical conversion of energy happens in the presence of electrolytes [12]. The CFCs are redox flow fuel cells, where electrolytes are fed continuously.…”

Pt-Ni and Pt-M-Ni (M = Ru, Sn) Anode Catalysts for Low-Temperature Acidic Direct Alcohol Fuel Cells: A Review

“…To overcome this drawback, binary and ternary Pt-based eletrocatalysts have been investigated. Compared to the MOR, few works reported the ethanol oxidation on Pt-Ni catalysts in acid media [20,46,[49][50][51][52], the most part as support data in papers addressed to the study of the EOR on ternary Ni-containing catalysts. The dependence of the Pt-Ni to Pt specific activity (SA Pt-Ni /SA Pt ) and mass activity (MA Pt-Ni /MA Pt ) ratios in acid media on Ni content in the Pt-Ni catalysts with various alloying degrees by different datasets [20,46,[49][50][51] is shown in Figure 4a,b.…”

“…Different works were addressed to the ethanol oxidation on Pt-Sn-Ni catalysts [50][51][52][75][76][77][78][79][80][81]. In all these works a comparison between Pt-Sn-Ni and Pt-Sn catalysts was made, and the MOR activity of Ni-containing catalysts was always higher than that of Pt-Sn.…”
