There are multiple sources of uncertainty in catalysis:
1. Catalyst Preparation: Variations in the synthesis methods, such as temperature, pH, and precursor materials, can lead to differences in the catalyst’s morphology and active sites. 2. Reaction Conditions: Fluctuations in temperature, pressure, and reactant concentrations can affect the catalytic activity and selectivity. 3. Measurement Techniques: Inaccuracies in analytical methods used to characterize catalysts and measure reaction rates can introduce uncertainty. 4. Intrinsic Properties: The inherent variability in the catalyst’s physical and chemical properties can also be a source of uncertainty.
