Prof. Pérez-Ramírez (1974) pursues the design of heterogeneous catalysts and reactor concepts devoted to sustainable technologies. The latter secures the efficient utilization of natural resources, the transition to renewables, reduced energy consumption and waste, and minimized environmental impact. Topics of current interest include the valorization of carbon dioxide, natural gas, plastics, and renewables, plastics recycling, decentralized ammonia synthesis, the design of low-nuclearity catalysts, the analysis of pore quality in hierarchically-organized materials, and the rational understanding of catalyst scale up. He is also responsible for educating undergraduate students at ETH Zurich in reaction engineering and catalysis, emphasizing the vital importance of these disciplines to tackle the current and future energy and environmental challenges of society. He is also director of the National Centre of Competence in Research, NCCR Catalysis.
