One‐pot synthesis of Pd‐MoO ₂ /C by microwave sintering as an efficient electrocatalyst for ethanol oxidation reaction

Abstract

Summary The composite catalysts of Pd‐MoO2/C for ethanol oxidation reaction (EOR) were prepared by microwave sintering. MoO3 was thermally reduced to MoO2 by carbon black in the preparing process of the Pd‐MoO2/C material. The TEM analysis showed that Pd‐MoO2 was well polymerized. Chronoamperometric, cyclic voltammetry, and electrochemical impedance spectra methods were applied to reveal the performance for EOR at room temperature. The Pd‐MoO2/C electrode exhibited considerable high activity and stability. MoO2 as a co‐catalyst significantly improved the catalytic activity of Pd‐MoO2/C for EOR.

Towards more active and stable PdAgCr electrocatalysts for formic acid electrooxidation: The role of optimization via response surface methodology

“…The progressive depletion of fossil fuels and increasing greenhouse gas emissions increases the importance of the investigation of alternative energy sources . Hydrogen polymer electrolyte fuel cell is the potential device that can overcome these problems . Hydrogen is accepted to be the energy source of the future instead of the endangered fossil fuels .…”

“…Due to these drawbacks about hydrogen fuel cells, direct liquid‐fed fuel cells (methanol, ethanol, dimethyl ether, etc.) have become popular among researchers . Compared with other fuels, formic acid represents many advantages such as being non‐poisonous, displaying low crossover through the membrane, and having high electromotive force (1.4 V) in direct formic acid fuel cell.…”
