Lecture Title
Fundamental Concepts in Heterogeneous Catalysis
Lecture Abstract
This lecture provides an overview of heterogeneous catalysis, focusing on its core principles, mechanisms, and applications. The session begins by exploring the multiscale nature of catalysis, from the molecular level (e.g., active sites, adsorption, and surface reactions) to the macroscopic level (e.g., reactor design and industrial processes).
Key topics—such as the difference between chemisorption and physisorption, the role of catalyst characterization techniques (including spectroscopy and BET analysis), and the basics of reaction kinetics (e.g., Langmuir-Hinshelwood and Eley-Rideal models)—will be presented. Meanwhile, catalyst synthesis methods (e.g., impregnation, sol-gel processes) and challenges like deactivation and regeneration will be briefly addressed.
The lecture will also touch upon the use of computational tools like DFT and the integration of catalysis in sustainable processes, such as biorefineries. We will also discuss frequent pitfalls in catalysis—such as neglecting mass transfer limitations—so students can anticipate and prevent them in their own practical work.
