Halving Hydrogen
Like ripping open a dinner roll, a fuel cell catalyst that converts hydrogen into electricity must tear open a hydrogen molecule. Now researchers have captured a view of such a catalyst holding onto the two halves of its hydrogen feast.
Grain Boundaries Accelerate Hydrogen Insertion into Palladium Nanostructures
Hydrogen preferentially inserts at grain boundaries between interconnected chains of palladium nanoparticles, which have a lower energy barrier for hydrogen incorporation into the material.
National Hydrogen Day 2021
National Hydrogen Day is around the corner. Join PNNL's Jamie Holladay on October 5 as he provides his perspectives on the potential scale of hydrogen use. It will be a gas!
New Catalyst Outshines Platinum for Producing Hydrogen
New PNNL research shows that a pairing of humble minerals outshines other reactive materials when it comes to producing hydrogen.
A Fast Electrocatalyst for Oxidation of Hydrogen
New results reported in Chemical Communications describe the synthesis, structure, and catalytic reactivity of a nickel complex that is the fastest molecular electrocatalyst for oxidation of hydrogen.
Predicting the Thermodynamics and Kinetics of Catalytic Hydrogenation
Catalysts that efficiently transfer hydrogen for storage in organic hydrogen carriers are key for more sustainable generation and use of hydrogen. New research identifies activity descriptors that can accelerate novel catalyst development.
Hydrogen Spillover Regulates Catalysis
Electronic modifications from hydrogen spillover onto the oxide support increase the activity of single-atom rhodium catalysts.
Morris Bullock Co-Chairs Hydrogen Roundtable
Lab Fellow Morris Bullock co-chaired a roundtable that discussed the scientific and technical barriers to carbon-neutral hydrogen production.
Storing Hydrogen on Materials
Newly funded research will look at the underlying science of controlling hydrogen interactions with two-dimensional materials composed of carbon, boron, and nitrogen.
Mechanism of Iron-based Hydrogen Bond Cleavage Revealed
Scientists at PNNL's Center for Molecular Electrocatalysis (CME) are working to understand the fundamental reactivity of H2 that could contribute to making hydrogen a more widely used fuel source.
