1. Search Strategies: Use advanced search options, such as Boolean operators (AND, OR, NOT), to refine your search. For example, searching "heterogeneous catalysis AND green chemistry" can yield focused results. 2. Keyword Selection: Choose specific and relevant keywords. For instance, terms like "zeolite catalysts," "enzymatic catalysis," or "photocatalysis" can help you find pertinent studies. 3. Stay Updated: Set up alerts for new publications in your area of interest. Many databases offer this feature to keep you informed about the latest research. 4. Citation Tracking: Use citation tracking tools to find influential papers and see how research evolves over time.
