Ammonia (NH3), a ubiquitous compound, was generated in excess of 187 million tons globally in 2020. Roughly 85% is employed in the creation of nitrogenous fertilizers, while the remainder is used for refining petroleum, producing various other chemicals, and manufacturing synthetic fibers like nylon. However, these processes come with a substantial energy expenditure. Presently, the […]

A catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. The study of enzymes has provided us many of the prototypical concepts of catalysis, including the idea that a catalyst lowers the barrier to reaction and thereby accelerates the approach to chemical equilibrium, without altering […]

When we consider the concepts metal and catalysis, we tend to assume quite matter-of-factly that the metal will be the catalyst. This assumption is based on the fact that metals can be found in reactions where they act as catalysts or co-catalysts in the form of coordination and organometallic compounds, nano-sized or bulk materials and […]
