Surface Chemistry of Catalysts

The surface properties of materials play a crucial role in determining their functionality, impacting applications ranging from catalysis to batteries and electronics. At the Gross Lab, we investigate how surface characteristics influence the reactivity of functional materials, with a particular focus on catalysts. Using advanced spectroscopy and microscopy techniques, we aim to uncover fundamental chemical principles that guide the development of greener, more efficient catalysts with enhanced reactivity, improved yields, and a reduced environmental footprint.

Addressing the major energy challenges of the 21st century requires the design of optimized catalysts with precise control over their reactivity and selectivity. We explore the fundamental factors governing catalytic performance by designing nanostructures with tailored size, composition, and morphology. Our expertise lies in single-particle analysis, utilizing high-resolution infrared nanospectroscopy to map catalytic reactivity at the nanoscale with an exceptional spatial resolution of 20 nm.
Self-Assembly and Functionality of Molecular Monolayers Self-assembled monolayers (SAMs) consist of atoms or molecules that spontaneously adsorb onto solid surfaces, offering a powerful strategy for tuning the properties of functional materials such as sensors, catalysts, and molecular switches. Among SAMs, N-heterocyclic carbenes (NHCs) have emerged as a promising molecular framework for creating thermally and chemically robust organic monolayers on metal surfaces. In the Gross Lab, we synthesize diverse NHCs, characterize their properties using both in-house and synchrotron-based spectroscopy techniques, and explore their functional applications.
