Several factors can influence the quality of a catalyst, including:
Surface Area: Higher surface area generally improves catalyst activity. Active Sites: The number and nature of active sites directly affect the catalyst's performance. Support Material: The choice of support material can influence the dispersion and stability of the active sites. Reaction Conditions: Temperature, pressure, and pH can all impact catalyst efficiency and longevity. Poisoning: Exposure to impurities can reduce catalyst activity and selectivity.
