However, the anodic reaction of DEFCs, that is, the ethanol oxidation reaction (EOR), suffers from poor efficiency due to the low selectivity to CO2 (C1 pathway) and high selectivity to CH3COOH (C2 pathway). In this study, the selective EOR to CO2 can be achieved at the Rh–SnO2 ...
Water acts as part of the ethanol oxidation reaction. This reaction acts as a source of an extra oxygen added to form acetic acid. What is the chemical reaction of ethanol? Ethanol can undergo many chemical reactions. This reaction includes oxidation, forming ethanal and acetic acid, acid-base...
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. ...
15. The development of highly active and low-cost electrocatalysts for the ethanol oxidation reaction (EOR) lays at the heart of DEFCs16,17,18,19,20,21,22,23,24,25. Down-sizing of metal nanoparticles into individual metal sites is commonly regarded as an efficient approach to enhance the ...
Direct ethanol fuel cells have been widely investigated as nontoxic and low-corrosive energy conversion devices with high energy and power densities. It is still challenging to develop high-activity and durable catalysts for a complete ethanol oxidation reaction on the anode and accelerated oxygen reduc...
Abstract High-quality Pt-based catalysts are highly desirable for ethanol oxidation reaction (EOR), which is of critical importance for the commercial applications of direct ethanol fuel cells (DEFCs). However, most of the Pt-based catalysts have suffered from high cost and low operation durability...
