Research Interests

Research activities are focused in the field of Heterogeneous Catalysis and, especially, in materials synthesis and characterization, catalyst development and evaluation, and investigation of reaction kinetics and mechanisms, with emphasis given in environmental and energy-related applications:

  • Hydrogenation of carbon dioxide (CO2) for methane (CH4) production.
  • Production of hydrogen for fuel cells, by reformation of Liquefied Petroleum Gas, biogas, biomass-derived ethanol etc.
  • Removal of carbon monoxide (CO) from hydrogen-rich reformate streams via selective methanation of CO.
  • Development of Water-Gas Shift (WGS) catalysts for fuel processors used in proton exchange membrane (PEM) fuel cell systems.
