Current Research Projects
Metal oxide catalysts for CO2 conversion usually comprise of nanocrystalline materials in which the catalytically active sites are few and often undetectable i.e., grain boundaries and defect sites. Consequently, these materials are not amenable to atomic level understanding of electrocatalytic CO2 conversion. Therefore, our main research goal is to prepare rationally designed, supported (Iron, Fe) metal-oxo/hydroxo and metal-sulfoxo single-site and nanocluster catalysts for operando structure-activity relationships studies in catalytic CO2 conversion and CH4 oxidation. We draw lessons and analogies from traditional organometallic chemistry to inform approaches to understanding and tuning the coordination chemistry of heterogeneous single-site iron-based catalysts supported on polymers and other metal oxides. Our research is informed by vibrational and optical spectroscopic techniques as well as electroanalytical and computational chemistry methods relevant to structure and reaction mechanism elucidation.
Our research addresses three key challenges:
- Insights into the structural stability, precision and evolution of catalytically active clusters.
- Understanding the phenomena underpinning the interaction of clusters and their support relevant to the geometric and electronic effects around the single-atom (single-site) Fe centers.
- Systematic design and synthesis of metal oxo, hydroxo and sulfoxo clusters with tunable electronic structure for applications towards CO2 reduction and H2O oxidation.
