Metal-Free Catalysts

For the production of materials, the generation and storage of clean energy, as well as numerous other crucial industrial processes, metals and metal oxides are frequently used as catalysts. Metal-based catalysts, on the other hand, are more expensive, less selective, less durable, more prone to gas poisoning, and worse for the environment. As a productive, affordable, and metal-free substitute for platinum for oxygen reduction in fuel cells, a new class of catalyst based on earth-abundant carbon materials was discovered in 2009. Since then, significant advancements have been made, and an expanding number of catalytic processes have shown to benefit from carbon-based, metal-free catalysts. In the fields of polymer and material sciences, novel polymerizations based on alkyne monomers are developing into a potent tool to create polymers with distinctive structures and cutting-edge functions, and in recent decades, scientists have become interested in creating a variety of novel polymerizations. In this context, catalytic systems are crucial for influencing the effectiveness of polymerization and the properties of the resulting polymers.
