Why are enzymes so efficient catalysts?5 answersEnzymes are highly efficient catalysts due to several factors. Firstly, enzymes operate under milder reaction conditions, which reduces energy requirements and allows for more sustainable and cost-effective processes. Secondly, enzymes have evolved to minimize energy wastage, optimizing the use of available energy and maximizing power output for a given change in Gibbs energy. Thirdly, enzymes exhibit excellent performance and selectivity, making them ideal for chemical transformations in both aqueous and nonaqueous media. Additionally, enzymes are not rigid structures but undergo internal motions and conformational fluctuations, allowing for dynamic interactions with substrates and facilitating catalysis. Furthermore, enzymes possess three-dimensional catalytic sites that play a crucial role in their catalytic activity, as demonstrated by the impact of the coordination environment of metal ions in metalloenzymes. Overall, enzymes' efficiency as catalysts stems from their ability to operate under mild conditions, optimize energy usage, exhibit high selectivity, and dynamically interact with substrates.

How are transition metals used as catalysts?5 answersTransition metals are used as catalysts in various applications. Surface engineering strategies such as heteroatom doping, vacancy engineering, strain regulation, heterojunction effect, and surface reconstruction can optimize the surface electronic structure of the catalysts, expose more active sites, and enhance water electrolysis performance. Transition metals can also catalyze the addition of hydridoboranes to unsaturated organic molecules, and this reaction has grown to include the use of earth-abundant metal catalysts and a wider range of organic substrates. In industrial organic processes, transition metal catalysts, including Ir- and Pd-based catalysts, play a vital role in the large-scale production of chemicals. Homogeneous catalytic ozonation, which involves the insertion of transition metals in solution, is an efficient process for water and wastewater treatment, enhancing the production of hydroxyl radicals for better oxidation. The interplay between ligand and metal properties in transition metal complexes can be controlled by the "second coordination sphere," with hydrogen bonding interactions being particularly useful in programming the second coordination sphere and achieving superior properties in various metal catalyzed transformations.
