Laura Reyes has been featured in a recent ACCN article for her involvement in green chemistry. Her role with the Green Chemistry Initiative (GCI) at UofT and her PhD project focused on investigating how CO2 and H2 interact with the surface of metal oxides are also presented.
The full article can be read on the ACCN website.
The Transformative Research to Combat Climate Change Challenge Workshop will be hosted by UofT on Wednesday October 12. This workshop will focus on converting CO2 to value-added products to enable energy security, environment protection, and climate control.
More information can be found on the information package.
Congratulations to Mireille Ghoussoub for publishing her first paper entitled “Metadynamics-Biased ab Initio Molecular Dynamics Study of Heterogeneous CO2 Reduction via Surface Frustrated Lewis Pairs” in the elite journal ACS Catalysis. Mireille investigated theoretically the effect of temperature on the surface FLP-driven RWGS reaction, CO2 + H2 à CO + H2O. She successfully probed for the first time the mechanism of the RGWS reaction over the defect laden In2O3−x(OH)y surface at finite temperatures of 20 and 180 °C. She was able to map the free energy surfaces for the entire reaction pathway, transition states and locations of energy minima, illustrated in the diagram, to obtain the energetics for the activation of H2 and the capture and reduction of CO2. Her results attest to the interesting types of surface chemistry that can be enabled by FLP surface sites, exemplified in this study by the heterogeneous RWGS reaction.

A paper by Laura, Paul, and Abdinoor reports the use of a hybrid catalyst consisting of In2O3-x(OH)y grown on an ultrablack vertically aligned Si nanowire support to reduce CO2 to CO. The ultrablack support improves light harvesting efficiency by converting the excess solar spectrum into heat to drive the catalytic reaction. This study provides a general advance into the design of catalysts for solar fuels.
