The utility of heatmaps in catalysis lies in their ability to condense large amounts of data into a visually intuitive format. They enable researchers to: - Quickly identify optimal conditions for catalytic reactions. - Detect regions of high and low activity within the parameter space. - Compare the performance of different catalysts under similar conditions. - Visualize the interplay between various reaction parameters. - Identify trends and potential correlations that might not be obvious from raw data.
