Catalysis has an important role in green and sustainable chemistry. The notion of cooperative catalysis, whereby more than one chemical entities work together to catalyze a chemical process, has gained momentums in recent years. Such cooperative catalysis may bring in new tools in catalyst design, and may overcome limitations of single-site catalysis. In this presentation I will describe several recent examples of our work covering cooperative catalysis in the three separate domains of catalysis: molecular, bio, and hetereogeneoues (electro) catalysis. I hope to demonstrate cooperative catalysis as a universal design principle for all types of catalysts
