Assistant Professor in Chemical Engineering
Achieving a sustainable energy economy is undoubtedly one of the biggest challenges of the 21st century. The Higgins Lab at McMaster University focuses on addressing this challenge through the design, synthesis and characterization of novel nanomaterial catalysts, and their integration into electrochemical devices, such as fuel cells or electrolyzers. Nanomaterial catalysts and electrochemical devices will be integral parts of a sustainable energy economy, as they will enable the interconversion of electrical and chemical energy. Put simply, they harness renewable sources of electricity (wind, solar, hydro) to produce the fuels and chemicals that society depends upon.
Students in the Higgins group apply catalyst design principles (i.e., an understanding of what makes a catalyst good) to synthesize nanomaterial catalysts designed on the atomic scale to possess desirable structures and properties. The nanomaterial catalysts are then tested for electrochemical activity towards small molecule conversions, focusing on the use of environmentally abundant molecules as reactants (i.e., O2, N2, H2O, CH4) to produce fuels, chemicals and fertilizers. Catalyst structure-property-performance relationships are established through extensive spectroscopic and microscopic nanomaterial characterization using advanced techniques available at McMaster University, including at the state-of-the-art Canadian Centre for Electron Microscopy facilities. Best in class nanomaterial catalysts are integrated into working electrochemical device prototypes that are engineered for performance validation and demonstration.
