Welcome to Carbons & Catalysts Group Website! Research group picture
Mission StatementThe purpose of our research is to understand and optimize carbons and catalysts for applications in energy, environmental and materials industries. In particular, we strive to develop less expensive products from abundant domestic resources such as biomass and coal. We also provide consulting and advising services in these areas to both public and private institutions. StaffProfessors:Ximena GarcíaAlfredo L. Gordon Romel Jiménez Ljubisa R.
