Microelectrodes are crucial in catalysis for several reasons. Firstly, they enable the study of reaction intermediates and products at a very local level, offering detailed insights into the reaction pathways. Secondly, their high sensitivity allows for the detection of minute amounts of catalytic activity, which is essential for screening and optimizing catalysts. Lastly, microelectrodes can operate in environments where conventional electrodes cannot, such as within biological tissues or in microreactors.
