    Biography

    José C. Conesa, M.Sc in Physics at the Barcelona University in 1974 and PhD in Chemistry at the Complutense University of Madrid in 1977, belongs since 1979 to the research staff of the ICP, being now in it Vice-Director.

    His specialty is the physical chemistry of catalysts active in redox processes, mainly those based on TiO2 or CeO2 (although he works also on other complex transition metal oxide catalysts), and of photoactive sulphides. He has undertaken the use of modern methods for the chemical synthesis of nanoparticles of these materials, studying also their structure and reactivity with advanced spectroscopies like EPR, XPS or those based on synchrotron radiation (including their use in situ and operando) and developing quantum models of their properties of catalytic interest.

    Besides some additional collaborations in other subjects, in which he applies  his experience in EPR, synchrotron radiation techniques or quantum calculations to different catalytic or nanoparticle systems, his scientific activity in the last years is centered mainly in two areas:

    Catalysts based on CeO2. This work was oriented until few years ago towards three-way catalysts for pollutant suppression in automobile exhaust gases, clarifying in this field phenomena of metal-support interaction between nanoparticles of Pt, Rh, Pd or their alloys and ceria or ceria-zirconia surfaces At present it is oriented to applications in energy: catalytic anodes for solid oxide fuel cells (SOFCs) that convert directly methane without pre-reforming avoiding carbon formation, and CuO-CeO2 systems for the production of CO-free H2 in fuel reforming technologies.

    Materials for a more efficient use of solar energy. Based on a long experience on photocatalysis with TiO2 and its surface reaction mechanisms, it is oriented now to photoactive solids able to use more efficiently solar light. To this aim he works in the design, solvothermal synthesis and use of sulphides of In, Sn and other metals as photocatalysts and new photovoltaic materials. These are obtained with electronic structures that allow utilizing wider ranges of the solar spectrum by coupling the absorption of two low energy photons to achieve electronic excitations of higher energy; in this way it is possible to increase significantly the solar efficiency of photovoltaic cells or of systems performing the photocatalytic production of hydrogen from water.

    He is author or coauthor of over 160 papers in international journals, which according to the ISI Web of Science database have received more than 4700 citations, with a Hirsch index h=42; he is also coauthor of five patents on new materials for the use of solar energy.
