PNNL Materials Scientists Publish Review Article on STEM Analysis of Oxide Interfaces

Materials scientists Dr. Steven R. Spurgeon and Dr. Scott A. Chambers, both of PNNL, recently published a review article on the characterization of oxide interfaces using advanced scanning transmission electron microscopy (STEM). The article appears in the August 2017 release of Elsevierís Encyclopedia of Interfacial Chemistry: Surface Science and Electrochemistry (DOI: 10.1016/B978-0-12-409547-2.12877-X).

The Pivotal Step in Turning Carbon Dioxide

What if we could turn carbon dioxide into a feedstock to create fuels or other chemicals? The challenge is designing effective processes that yield only the desired chemical. Scientists need a clear understanding of the pivotal steps. Now, scientists at DOE's Pacific Northwest National Laboratory have learned a key step involving formate.

Meeting the Need for Catalytic Speed

The rates to convert agricultural and other organic waste into biofuels at low temperatures are currently too low to be economically competitive. Scientists at DOE's Pacific Northwest National Laboratory and TU München in Germany developed ways to accelerate the reaction rates. The solution was forcing a key reaction to occur in the nano-sized confining pores inside zeolites.

Converting Carbon Dioxide in Water

Turning plentiful carbon dioxide into a chemical feedstock would wring value from the greenhouse gas. However, the traditional approach is costly and produces unwanted byproducts. Scientists designed a water-soluble catalyst for this transformation. They did so by understanding each of the steps in converting carbon dioxide to formate.
