The Catalysts and Surfaces Division was created with the institute in 1982, based on the research team of Prof. Daniel Löffler. The work focused basically in the area of heterogeneous catalysis. In 1990, the group extended its interests to issues of physical chemistry of surfaces; in particular, the study of semiconductor surfaces and interfaces, their formation, morphology, and properties. Current interests in heterogeneous catalysis include the development of conventional, nano and structured catalysts, supported on commercial or natural materials applied to water pollution abatement and the biorremediation of xenobiotics.
