Various materials used in catalytic processes undergo flexural testing. These include: - Ceramic Supports: Commonly used in heterogeneous catalysis due to their thermal stability and mechanical strength. - Zeolites: Microporous aluminosilicate minerals used as catalysts and adsorbents. - Metal-Organic Frameworks (MOFs): Composed of metal ions coordinated to organic ligands, offering high surface areas and tunable properties. - Catalyst Coatings: Thin layers of catalytic material applied to substrates to enhance reactivity.
