Information:

The Schaak group’s main research interests are in the general area of synthetic inorganic nanochemistry.  We identify target materials systems that underpin practical, relevant, and emerging applications, but for which a fundamentally interesting synthetic bottleneck precludes their formation.  We then seek to develop new synthetic tools that overcome these challenges, both to generate and study our specific target materials and also to provide conceptually new synthetic approaches that are broadly applicable.  Our targets, materials systems, and applications are diverse, spanning metals, metal alloys, metal oxides, metal chalcogenides, metal phosphides, metal carbides, and metal borides for use in catalysis, photonics, magnetic separations, and energy conversion and storage.  Current research projects include (a) discovering and studing new non-noble-metal catalysts, comprised of inexpensive and Earth-abundant elements, for solar energy conversion and fuel cell applications, (b) developing a “total synthesis” toolkit for the construction of multi-functional hybrid inorganic nanostructures, and (c) synthesizing and studying the formation pathways of metal chalcogenide nanostructures with useful catalytic, magnetic, and optical properties.
