Preparation of PtSn/C skeletal-type electrocatalyst for ethanol oxidation

Solvothermal Synthesis of Mesoporous 3D‐CuCo2O4 Hollow Tubes as Efficient Electrocatalysts for Methanol Electro‐Oxidation

“…Chronoamperometry (CA) test was carried out to study the electrochemical activity and stability of all electrodes. This method measures the current‐time dependence of the electrode in a diffusion‐controlled medium . As shown in Figure a and Figure S12, CA test of bare Ni foam, CuCo 2 O 4 electrodes synthesized with and without PVP, CuO and Co 3 O 4 were carried out at 0.5 V (vs. SCE) for 2500 seconds.…”

Addition of iron oxide to Pt-based catalyst to enhance the catalytic activity of ethanol electrooxidation

“…Sn-based catalysts are the best ones for the oxidation of ethanol[14,[28][29][30][87][88][89][90][91][92]. We have investigated the role of Sn in this reaction[5,16,21,26,27,44,77,93] and our results have shown that Sn exhibits efficient and enhanced electrocatalytic ability toward ethanol.…”

Preparation of PtSn/C Skeletal-Type Electrocatalysts for Ethanol Electro-Oxidation

“…On the other hand, the complete oxidation of ethanol to CO 2 in fuel cells is still a challenge to be overcome, due to difficulty in breaking the C-C bond. PtSn/C electrocatalysts have been shown to be the most active for ethanol electrooxidation, however, their activity depends largely on the preparation process (1). A recent study (2) showed that a new class of electrocatalysts (PtCu/C) of high activity, can be obtained by structural modification of the Pt-Cu alloy by partial leaching of Cu by electrochemical treatment (dealloying process).…”
