Each year we compile a list of the biggest advances made by scientists, engineers, and those who support their work at the U.S. Department of Energy’s Brookhaven National Laboratory. From unraveling new details of the particle soup that filled the early universe to designing improvements for batteries, x-ray imaging, and even glass, this year’s selections span a spectrum of size scales and fields of science. Read on for a recap of what our passion for discovery has uncovered this year. (…)
4. Low-Temperature Hydrogen Catalyst
Brookhaven chemists conducted essential studies to decipher the details of a new low-temperature catalyst for producing high-purity hydrogen gas. Developed by collaborators at Peking University, the catalyst operates at low temperature and pressure, and could be particularly useful in fuel-cell-powered cars. The Brookhaven team analyzed the catalyst as it was operating under industrial conditions using x-ray diffraction at the National Synchrotron Light Source (NSLS). These operando experiments revealed how the configuration of atoms changed under different operating conditions, including at different temperatures. The team then used those structural details to develop models and a theoretical framework to explain why the catalyst works so well, using computational resources at Brookhaven’s Center for Functional Nanomaterials (CFN).
