Heterogeneous and Homogeneous Catalysis
Heterogeneous catalysis is a phenomenon in which a solid material speeds up a chemical reaction without being part of the reaction's overall stoichiometric equation. Sequences of reactions involving fluid-phase reagents and the exposed layer of the solid catalyst surface are commonly used in heterogeneous catalysis. Because of its ability to accelerate a chemical reaction to equilibrium and to selectively accelerate a desirable chemical reaction of complex chemical processes to equilibrium, heterogeneous catalysis by solids plays a vital role in the chemical industry and environmental remediation. Homogeneous catalysis is a central concept in modern chemical processes, providing a mechanism for reactions to occur under controlled conditions, leading to high yields and minimal byproducts. The catalyst, being in the same phase as the reactants, interacts intimately with the molecules involved in the reaction, promoting faster and more efficient transformations

Environmental catalysis is a multidisciplinary research subject to which an increasing number of chemists, materials scientists, and environmentalists have dedicated their attention due to its promising potential for enhancing human health and quality of life. Because of its numerous applications in carbon dioxide reduction, oxidation of volatile organic compounds (VOCs), removal of aqueous organic contaminants and disinfection, and water splitting, photocatalysis remains a research focus for the environmental catalysis community. Environmental Catalysis combines analysis, theory, computation and synthesis to enable the most cutting-edge applications in biocatalysis, green chemistry, environmental remediation, and our understanding of how pollutants interact with natural systems.
Bio catalysis and Biotransformation’s
The use of biomolecules, particularly enzymes or entire cells, as catalysts for the creation of novel materials is known as biocatalysis. Enzymes and microorganisms have been exploited in the creation of industrially important products for hundreds of years, such as the fermentation of alcohol and the enzymatic breakdown of milk proteins in cheese. Since the need for intense use of natural resources with reduced pollution has become a global trend, biocatalysis-based technologies are becoming a blooming sector of research and industrial applications. Biocatalysis is critical for solving global concerns such as climate change, fossil fuel substitution, and feeding a growing population, primarily because bioprocessing in the food, feed, and nonfood industries increases resource efficiency by extracting more value from raw biomaterials. Biotransformation is the process by which lipophilic (fat-soluble), xenobiotic (foreign), and endobiotic (endogenous) substances are transformed to more hydrophilic compounds in the body through enzyme processes (water-soluble).
