Using an innovative chemical strategy developed at UVA, however, a team of researchers led by chemistry professors Sen Zhang and T. Brent Gunnoe have produced a new form of catalyst using the elements cobalt and titanium. The advantage of these elements is that they are much more abundant in nature than other commonly used catalytic materials containing precious metals such as iridium or ruthenium. “The new process involves creating active catalytic sites at the atomic level on the surface of titanium oxide nanocrystals, a technique that produces a durable catalytic material and one that is better at triggering the oxygen evolution reaction.” Zhang said. “New approaches to efficient oxygen evolution reaction catalysts and enhanced fundamental understanding of them are key to enabling a possible transition to scaled-use of renewable solar energy. This work is a perfect example of how to optimize the catalyst efficiency for clean energy technology by tuning nanomaterials at the atomic scale.”
