Understanding and Tailoring Metal-Support Interactions in Heterogeneous Catalysts

Platinum is an archetypical catalyst used for a variety of applications, including fuel cells, electrolyzers, and processes involved in the production of renewable chemicals. Unfortunately, the use of platinum as a catalyst is cost prohibitive. A variety of options is available to mitigate the cost, one of which includes synthesizing high surface area platinum catalyst. Most often, the catalysts synthesized for fuel cells and electrolyzers consist of platinum deposited on a high surface area carbon support.

R&D features Ames Lab nanocatalyst research

R&D magazine carried a news release on work by Ames Lab researchers creating a  faster, cleaner biofuel refining technology that not only combines processes, it uses widely available materials to reduce costs. The key component is a nanoparticle that is able to perform two processing functions at once for the production of green diesel, an alternative fuel created from the hydrogenation of oils from renewable feedstocks like algae.

Using defects in diamond to probe nanoscale magnetic structures

Diamonds have the reputation as flawless, sparkling gems. In scientific applications, their hardness is used to test the highest pressure levels. But researchers at the Ames Laboratory plan to exploit defects in diamond's crystal structure, known as nitrogen vacancy centers, to build a device that will give them the ability to visualize magnetic fields produced by magnetic nanostructures.
