Catalysis at electrodes
Catalysis at electrodes
Catalysis at electrodes refers to the process of accelerating chemical reactions by utilizing an electrode as a catalyst. Electrodes play a crucial role in various electrochemical systems such as fuel cells, electrolyzers, and batteries. Through catalysis, these electrodes enhance the reaction rates and improve the overall efficiency of the electrochemical system. The choice of catalyst greatly impacts the performance of the electrode since it facilitates the electron transfer and lowers the activation energy required for reaction initiation. Commonly used catalysts include transition metal oxides, noble metals like platinum and palladium, carbon-based materials, and metal nanoparticles. Researchers continue to explore new materials and techniques to optimize catalytic activity at electrodes, aiming for increased energy conversion efficiency, reduced production costs, and improved long-term stability in industrial applications. Catalysis at electrodes is a multidisciplinary field that combines knowledge from materials science, chemistry, physics, and electrochemistry to address current energy challenges through sustainable solutions.
