John Keith was among the Emerging Investigators in 2017 recommended by experts in the field of materials chemistry research in a themed issue of the Journal of Materials Chemistry A, published by the Royal Society of Chemistry. His article “Computational investigation of CO2 electroreduction on tin oxide and predictions of Ti, V, Nb and Zr dopants for improved catalysis” published in the issue outlines the work of Keith and his team on improving the performance of tin electrocatalysts for CO2 reduction. By using computational quantum chemistry modeling, the researchers studied reaction mechanisms on partially-reduced tin oxide surfaces and which elemental dopant additives can be added to make the CO2 conversion more energy efficient.

Some of the dopants we modeled were already known to improve CO2 conversion energy efficiencies, and since our models could predict those cases we’re confident the other dopants we predicted as improving efficiencies are very promising for future work,” said Keith. “Our work demonstrates how we can modify tin-based oxide materials to make them better at converting CO2 into useful chemicals and fuels.”

John Keith studies atomic scale reaction mechanisms to understand how to design better catalysts whether the goal is a commodity chemical made from CO2 or an anticorrosion coating for the US Navy. Joining Keith on the study were PhD students Karthikeyan Saravanan and Yasemin Basdogan as well as James Dean, a former undergraduate researcher that was supported by Pitt’s NSF-sponsored Particle-based Functional Materials Research Experience for Undergraduates program.
