Catalysis is a field within chemistry that focuses on catalysts, substances that accelerate chemical reactions without being used up in the process. Catalysts play a vital role in industrial and biological processes by facilitating more effective and specific changes in molecules. This area covers homogeneous catalysis, where catalysts are in the same phase as reactants, and heterogeneous catalysis, where catalysts are in a different phase. Catalysis is indispensable for the production of chemicals, fuel refinement, pharmaceutical manufacturing, and the creation of sustainable energy solutions. Progress in catalysis leads to more environmentally friendly processes and advancements in different chemical sectors.
