ELECTROCATALYSIS Meaning and
Definition
-
Electrocatalysis is a branch of chemistry that focuses on the study of chemical reactions that occur at the interface between an electrode and an electroactive material (usually a catalyst). It involves the utilization of an electrical current to drive or control a chemical reaction, thereby enhancing the reaction rate or efficiency.
The process of electrocatalysis typically involves the transfer of electrons between the electrode and the reactants or products. The electrode acts as a platform for facilitating the reaction, while the electroactive material, or catalyst, lowers the activation energy required for the reaction to occur.
Electrocatalysis finds extensive application in various fields, including energy conversion, electrochemical sensors and detectors, and electrosynthesis of chemicals. In energy conversion, electrocatalysts play a crucial role in mediating the conversion of chemical energy into electrical energy or vice versa, as in fuel cells, batteries, and electrolyzers.
Understanding the principles and mechanisms of electrocatalysis is essential in developing efficient and sustainable energy technologies. Researchers focus on designing and optimizing catalysts that exhibit high activity, selectivity, and stability. They also aim to improve the understanding of the structure-activity relationship of electrocatalysts.
Overall, electrocatalysis plays a significant role in advancing fields related to energy, environment, and chemical synthesis, and its continued development is critical for achieving more efficient and sustainable chemical and energy conversion processes.

Etymology of ELECTROCATALYSIS
The word "electrocatalysis" is derived from the combination of two root words: "electro" and "catalysis".
1. "Electro" comes from the Greek word "ēlektron", which means "amber" or "electricity". It refers to the phenomenon of electricity or electric charge.
2. "Catalysis" comes from the Greek word "katalysis", which means "dissolution" or "loosening". Later, it was adapted in chemistry to designate the process of accelerating or facilitating a chemical reaction without being consumed in the process.
Therefore, "electrocatalysis" is the combination of these words to describe the process of accelerating or facilitating a chemical reaction using electricity or electric charge as the driving force. It specifically refers to catalytic reactions that occur at electrified interfaces or in electrochemical systems.
