Several critical properties need to be characterized:
- Surface Area and Porosity: The surface area available for reactions and the porosity of the catalyst material. - Particle Size and Distribution: Size and distribution of catalyst particles can affect catalytic activity and selectivity. - Chemical Composition: The elemental and molecular composition of the catalyst. - Phase and Crystallinity: The structural phase and degree of crystallinity of the catalyst material. - Active Sites: Nature, number, and distribution of active sites. - Thermal Stability: How the catalyst behaves under different temperatures. - Electronic Properties: Electronic states and band structures which can affect reactivity.
