Turnover number (TON) is a key performance metric in catalysis that quantifies the efficiency of a catalyst in facilitating a reaction. It is defined as the number of substrate molecules converted to product per active site on the catalyst over a specific time period, usually expressed in terms of moles. This metric is crucial for assessing the activity of catalysts, especially nanostructured materials, as it helps to evaluate their effectiveness and suitability for various chemical processes.
