The procedure for cycling tests typically involves the following steps: 1. Activation: The catalyst is initially activated under specific conditions to reach its optimal state. 2. Reaction Cycle: The catalyst is subjected to the target reaction conditions for a defined period. 3. Regeneration: Post-reaction, the catalyst undergoes a regeneration process to restore its activity. This may involve _calcination_ or _reduction_. 4. Repetition: Steps 2 and 3 are repeated multiple times to assess the catalyst's performance over several cycles.
