What are the Challenges in Identifying Active Sites?
Identifying active sites is challenging due to the complexity of catalyst materials and the dynamic nature of catalytic processes. Some of the main challenges include:
Heterogeneity of Catalyst Surfaces: Catalysts often have varied surface structures, making it difficult to identify which sites are active. Operando Conditions: The active sites may change under different reaction conditions, requiring in situ analysis. Scale: The atomic-scale features of active sites require high-resolution techniques that are often complex and expensive.
