Prof. Dion Vlachos (left), director of UD’s Catalysis Center for Energy Innovation, and Joshua Lansford, a doctoral student in UD’s Department of Chemical and Biomolecular Engineering, are co-authors on the paper recently published in the journal Science Advances.

UD’s Vlachos and Lansford develop high-confidence approach for artificial intelligence-based models

October 19, 2020

They call it artificial intelligence — not because the intelligence is somehow fake. It’s real intelligence, but it’s still made by humans. That means AI — a power tool that can add speed, efficiency, insight and accuracy to a researcher’s work — has many limitations.

Climate-conscious consumers often take steps to curb their emissions of greenhouse gases. For example, you might drive a hybrid car to reduce your use of fossil fuels, which release carbon dioxide into the atmosphere during combustion. These approaches reduce the amount of carbon dioxide added to the atmosphere. Some scientists are also working on ways to subtract carbon dioxide from the atmosphere. The goal is to capture the greenhouse gas and transform it into another substance altogether. Sound like magic? It’s not — it’s chemistry. One of the leaders in this field of carbon capture and utilization is Feng Jiao, Robert Grasselli Development Professor of Chemical and Biomolecular Engineering at the University of Delaware.

JACS Paper Highlighted in Nature Catalysis

A collaboration of CCST faculty

A collaboration of CCST faculty; Prof. Feng Jiao (Robert Graselli Development Professor of Chemical and Biomolecular Engineering), Prof. Bingjun Xu (Centennial Development Professor of Chemical and Biomolecular Engineering) and Prof. Levi Thompson(Elizabeth Inez Kelly Professor of Engineering), just reported in the Journal of the American Chemical Society important findings on the function of Cu-catalyzed electrocatalytic transformation of carbon dioxide/monoxide to valuable multicarbon molecules, an attractive strategy for combating climate change. Using in situ surface-enhanced Raman spectroscopy (SERS) they investigate the speciation of four commonly used Cu surfaces, they show that surface oxygen-containing species indeed exist in the alkaline electrolyte at potentials relevant to the carbon oxides reduction reaction on all types of Cu surfaces investigated. The presence of CO is necessary to stabilize surface oxide/hydroxide species on the Cu foil but not for micro/nanostructured Cu. They conclude that while CuOx and CuOx/(OH)y species do exist under reaction conditions, these species are unlikely to be the active sites facilitating the formation of C2 oxygenates.
