Pt-Based Catalysts for Alcohol Oxidation

Abstract

The development of fuel cell technologies and the use of clean energy sources have recently accelerated considerably. Fuel cells are electrochemical devices that convert chemical energy into electrical energy with an efficiency of 40%-80%. Fuel cells have many advantages, such as high efficiency, environmental friendliness, silent operation, and light weight, and it can be applied in vehicles and power plants. A fuel cell consists of an anode, the electrolyte medium that transmits the hydrogen ion and the cathode. As the fuel feeds from the anode alcohol, the cathode meets the oxygen source for the air itself. As a result of reactions in the electrodes, electrical energy is produced and water vapor from cathode, waste fuel, and CO2 is given off from the anode as by-products. In this chapter, detailed information about the types and properties of platinum-based catalysts for the alcohol oxidation of fuel cells and their applications are provided by compiling information from the research literature. In addition, economic evaluations were made by specifying the positive and negative aspects of these materials. © 2021 Elsevier Inc. All rights reserved.
