Current Research

The Cybulskis lab focuses on developing heterogeneous catalysts with targeted structures and predictable functions that can be tuned to enable new reaction pathways and perform challenging chemical transformations with enhanced selectivity. We are primarily interested in the synthesis of inorganic solid catalysts, including oxide-supported metals and molecular sieves (e.g., microporous zeolites and zeotypes, mesoporous materials), for use in new, eco-friendly processes to convert carbon-based natural resources, such as petroleum, shale, and biomass-derived feedstocks, into value-added chemical products and fuels.

Our experimental research approach combines materials synthesis, catalyst characterization, fundamental reaction kinetics, and mechanistic studies to identify relevant chemical descriptors of catalytic behavior and develop protocols to tailor the physicochemical properties and macroscopic functionality of heterogeneous catalysts for specific reactions. Current research topics include:

  • Catalytic functionalization of light oxygenates, such as formaldehyde, to evaluate and tune molecular sieve performance
  • Tandem catalytic pathways for transforming light hydrocarbons into chemical intermediates and fuels
  • Synthesis of microporous molecular sieves with prescribed crystal structures by design
