Catalysis and Surface Processes

Rodolfo Zanella-Specia

Rodolfo Zanella is a chemical engineer (1998) from UNAM. He obtained his master’s degree in chemical engineering (2000) from UNAM and his Ph.D. in process engineering and catalysis from Université Pierre et Marie Curie–Paris VI (now Sorbonne Université), France, in 2003.

Following a postdoctoral fellowship at the Center for Applied Sciences and Technological Development (CCADET) of UNAM in 2004, he joined the institution as a research assistant in 2006 and was promoted to senior researcher in 2009. He later served as Academic Deputy from 2011 to 2013 and subsequently as Director of CCADET from 2013 to 2018. He was also Director of the Institute for Applied Sciences and Technology at UNAM from 2018 to 2022, and Director of the UNAM Representative Office in France from 2022 to 2023. He currently serves as Coordinator of the University Seminar on Hydrocarbon Research at UNAM. He is a Level III member of Mexico’s National System of Researchers.

His research interests include photocatalytic hydrogen production via water splitting; catalysis for exhaust gas treatment (CO oxidation, NO reduction, and total oxidation); CO2 valorization (methanation and artificial photosynthesis); hydrogen production and purification (water–gas shift reaction and preferential CO oxidation); photocatalytic degradation of organic compounds; and the deposition of mono- and bimetallic nanoparticles on reducible and non-reducible oxide supports. His work also encompasses the synthesis of pure and doped metal oxides.

He has authored 186 research articles, which have received approximately 9,000 citations (H-index: 48), as well as 7 book chapters, and has led 24 funded research projects. He has supervised 38 BSc students, 19 MSc students, 7 PhD students, and 17 postdoctoral fellows.

He has been recognized twice by Elsevier as first author of highly cited papers in chemical engineering journals. He has also received the National University Award for Young Scientists from UNAM and has been recognized as one of the most cited researchers at UNAM in the field of chemistry.
