Dr. Larsen’s group works on a variety of projects related to catalysis, adsorption, and materials design. We currently have six major areas of research in our laboratory:
- Partial oxidation reactions over hybrid (organic/inorganic) Ti-containing gels;
- Synthesis of inorganic oxide materials with tailored porosities and well-defined
(catalytically active)metal particle sizes using macromolecular templates;
- Design of zeolite- and amorphous silica/cellulose composites for separation applications;
- Molecularly imprinted inorganic, and hybrid (organic/inorganic) oxides;
- Design of macroporous supports for immobilized enzymes utilized in reactions
involving bulky biomolecules; · Design of catalytic nanofibers based on electrospinning of sol-gels.
