Heterogeneous catalysis and surface chemistry; spectroscopic characterization of surfaces using Raman, infrared absorption, X-ray absorption spectroscopies, and solid state NMR; classical kinetics; chemisorption and physical adsorption to study structured catalysts and catalyst supports (MCM-41 and SBA-15 silica; microporous, multi- and single-walled carbon nanotubes, very small metal cluster catalysts, and catalytic synthesis of single-wall carbon nanotubes. A general philosophy and outline of previous research can be found in a recent review of “New catalytic concepts…”
