There are several reasons for the limited pool of reviewers in catalysis:
Specialization: Catalysis is a highly specialized field, and finding experts with the specific knowledge required to review certain topics can be challenging. Workload: Many experts in the field are already overburdened with their own research, teaching, and administrative duties, leaving little time for peer review. Conflict of Interest: Potential reviewers may have conflicts of interest that prevent them from impartially reviewing certain manuscripts.
