Functional inorganic solids & quantum materials
Most of the benchmark systems used in catalysis are inorganic in nature. And yet, commercially relevant catalysts constitute a tiny subset of the inorganic materials space. We have a long-standing interest in the de novo design of robust inorganic catalysts for hydrogen and oxygen evolution catalysis, informed by structure-property-function relationships. To this end, we explore new material concepts for catalysis, ranging from strain engineering in delafossites to transition metal oxide nanosheets for atom efficient catalysis. Along these lines, we explore the interface between quantum and energy materials to harness quantum effects for energy conversion and storage, e.g., for topological catalysis or spin-selective transformations.
