The Rise of Bio-Inspired Catalysts

In recent years, scientists have turned their attention to nature's impressive repertoire of catalysts, such as enzymes, to inspire the development of efficient and sustainable man-made systems. Bio-inspired catalysts mimic the structural and functional aspects of natural catalysts, offering advantages like high activity, selectivity, and compatibility with complex reaction environments.

The Power of Enzymes

Enzymes are biocatalysts found in living organisms that enable and accelerate various biochemical reactions. They possess remarkable catalytic significance due to their three-dimensional structures, active sites, and the ability to function under mild reaction conditions. By studying enzymes' functioning, scientists can design synthetic catalysts with similar attributes, fostering greener chemistry practices.

Examples of Bio-Inspired Catalysts

One prominent example of bio-inspired catalysts is the use of transition metals, such as ruthenium, iron, and nickel, in synthetic systems. These metals possess properties that resemble those of metalloenzymes. By incorporating ligands and mimicking the enzymatic active sites, chemists can create artificial catalysts for various chemical transformations.

Nature's Green Chemist: Photosystem II

Photosystem II, present in plants and cyanobacteria, is responsible for converting light energy into chemical energy via the water-splitting reaction. Scientists have long been fascinated by this complex enzyme and have been working to replicate its catalytic mechanism using synthetic catalysts. These bio-inspired systems offer a potential solution for renewable energy production by harnessing sunlight to generate hydrogen fuel.

The Magic of Nitrogenase

Nitrogenase is another intriguing enzyme found in nitrogen-fixing bacteria that converts atmospheric nitrogen into ammonia, a vital component for plant growth. The remarkable efficiency and selectivity of this enzyme have inspired the development of synthetic catalysts that can mimic its activity. These catalysts hold great potential for sustainable nitrogen fixation, reducing the need for energy-intensive industrial processes.

The Future of Sustainable Chemistry

Bio-inspired catalysts undoubtedly offer a promising future for sustainable chemistry. Their ability to reduce energy consumption, minimize waste generation, and enable environmentally friendly processes make them crucial tools for addressing global challenges such as climate change and resource scarcity.

The field of bio-inspired catalysts in organometallic chemistry continues to evolve rapidly, driven by the quest for sustainable solutions. With advancements that mimic nature's catalysts, scientists are unraveling the secrets behind complex enzymatic reactions and creating innovative catalysts that can revolutionize various industries. These catalysts have the potential to pave the way for a greener future, taking us closer to a world where chemistry and sustainability go hand in hand.

In order to meet the ever-increasing demands for enantiopure compounds, heteroge- ous, homogeneous and enzymatic catalysis evolved independently in the past. Although all three approaches have yielded industrially viable processes, the latter two are the most widely used and can be regarded as complementary in many respects. Despite the progress in structural, computational and mechanistic studies, however, to date there is no universal recipe for the optimization of catalytic processes. Thus, a trial-and-error approach remains predominant in catalyst discovery and optimization. With the aim of complementing the well-established fields of homogeneous and enzymatic catalysis, organocatalysis and artificial metalloenzymes have enjoyed a recent revival. Artificial metalloenzymes, which are the focus of this book, result from comb- ing an active but unselective organometallic moiety with a macromolecular host. Kaiser and Whitesides suggested the possibility of creating artificial metallo- zymes as long ago as the late 1970s. However, there was a widespread belief that proteins and organometallic catalysts were incompatible with each other. This severely hampered research in this area at the interface between homogeneous and enzymatic catalysis. Since 2000, however, there has been a growing interest in the field of artificial metalloenzymes for enantioselective catalysis. The current state of the art and the potential for future development are p- sented in five well-balanced chapters. G. Roelfes, B. Feringa et al. summarize research relying on DNA as a macromolecular host for enantioselective catalysis.
