Universidad Autónoma del Estado de México, Mexico
Dra. Reyna Natividad holds a Ph.D. in Philosophy (Chemical Engineering) from the University of Birmingham, United Kingdom. She earned her Bachelor’s degree in Chemical Engineering and a Master’s degree in Metallurgy and Materials Science from Universidad Michoacana de San Nicolás de Hidalgo. Since 2005, she has served as Professor and Researcher at the Faculty of Chemistry, Universidad Autónoma del Estado de México, where she has taught numerous courses in the Chemical Engineering, Chemical Sciences, and Environmental Sciences graduate programs. Her research has significantly contributed to chemical and environmental engineering, resulting in 119 scientific publications with over 3,180 citations, 22 book chapters, and the supervision of 15 Ph.D., 21 M.Sc., and 23 undergraduate theses in Chemical Engineering. Her work focuses on the valorization of waste materials such as CO₂ and oils for fuel production, as well as process intensification for water remediation. She holds three patents granted by the Mexican Institute of Industrial Property (IMPI) and has an h-index of 33. Her academic excellence has been recognized through multiple distinctions, including membership in the Mexican Academy of Sciences (2025), Level 3 of the National System of Researchers (SNI), and the Marcos Moshinsky Research Chair for Young Scientists (2017).
Photo-catalyzed CO2 chemical reduction in aqueous media
Carbon dioxide is one of the most significant greenhouse gases, and reducing its concentration in the atmosphere has become a major research objective. Among the different mitigation strategies, photocatalysis stands out as a promising approach for CO2 valorization through its chemical conversion into value-added products such as fuels, hydrogen carriers or brick-molecules (e.g. methanol, formic acid, acetic acid). While CO2 photocatalytic reduction is commonly carried out in the gas phase, this work investigates the influence of reaction parameters-including photocatalyst type, irradiation wavelength, pH, hydrodynamics, catalyst concentration and temperature- when the reaction occurs in aqueous media (deionized water and NaOH solutions). Product distribution and selectivity will be analyzed using titania or pillared clays as supports of iron and copper species under UV and visible light irradiation. A life cycle analysis of the synthesis of the pillared clay catalyst will also be presented.
