Prof. Antonio R. Guerrero Ruiz studied Chemistry at the University of Granada (1975-1980) and received his PhD in 1983, performing research in the field of carbon supported nanoparticles (Fe, Ru) applied as catalysts of CO hydrogenation to hydrocarbons. By three postdoctoral positions: at the CNRS-Marseille (1984-85), where learns about microcalorimetry of chemisorption; at the CNRS-Lyon (1986), where acquired expertise on catalytic surface reactivity on metal oxides, and at the university of Alicante (1987-88), where developed bimetallic catalysts supported on activated carbons; he has completed his proficiency in chemistry reactions at solid surfaces. From 1989 he has been at the UNED-Spain firstly as Associate Prof. and from 2006 as Full Prof. of Inorganic Chemistry. He is an international referent in applying carbon materials (including graphenic and carbon nanotubes) as free metal catalysts or as supports of metallic nanoparticles. In his research studies, he has introduced surface reactivity tools to understanding the chemical steps occurring on the heterogeneous catalysis processes, such as studies using Isotopic Labelled reactants or operating Temporal Analysis of Products reactors or performing calorimetric experiments to evaluate the adsorptive-surface interactions. He has published more than 300 scientific papers with nearly 10.000 citations. He has educated more than 25 PhD students and collaborated with more than 100 researchers from up to 16 countries.
