Preprints are crucial in catalysis research for several reasons: 1. Rapid Dissemination: Catalysis research is often fast-paced, and preprints enable researchers to share their findings without the delays associated with traditional peer review. 2. Open Access: Anyone can access preprints, ensuring that knowledge is not restricted by subscription fees. 3. Feedback and Collaboration: Preprints allow researchers to receive feedback from the community, which can improve the quality of the final publication. They also foster collaboration and prevent duplication of effort.
