Tracers can be introduced into the catalytic system through various methods, including: - Gas-phase Injection: Suitable for gas-phase reactions, where tracers are mixed with reactant gases. - Liquid-phase Injection: Used for liquid-phase reactions, where tracers are dissolved in the reactant solution. - Solid-phase Injection: Involves embedding tracers in solid reactants or supports.
Each method has its own set of advantages and limitations, depending on the nature of the catalytic system and the type of tracer used.
