Scientists Achieve Difficult Chemical Step with Lower Energy Input
Researchers developed a new hybrid catalyst that achieved chemo-selective and site-selective hydrogenation of aromatic molecules under low pressure of dihydrogen and mild temperature.
The Contradictory Catalyst
Using a natural catalyst from bacteria for inspiration, researchers have now reported the fastest synthetic catalysts to date for hydrogen production-- producing 45 million hydrogen molecules per second.
New $90M PNNL Center to Focus on Solving Clean Energy’s Biggest Puzzles
PNNL’s new Energy Sciences Center has capabilities for scientists to advance solutions for storing clean hydrogen in chemical bonds.
Tracking Mechanisms of Crystallization in Real Time
iDREAM research shows that concentrated electrolytes in solution affect hydrogen bonding, ion interactions, and coordination geometries in currently unpredictable ways.
Marina Recognized as One of the Pioneering Women in Applied Physics
PNNL hydrogen expert Olga Marina has been named among the pioneering women in applied physics in a roadmap published in Journal of Physics D.
Oliver Gutiérrez Takes on a ‘Multidimensional Challenge’
Oliver Gutiérrez leads an electrocatalytic hydrogenation research team at PNNL that focuses on next-generation catalysts at the molecular level and in an aqueous state.
When Less Is More: Fewer Proton Relays Improve Catalytic Rates
By directly comparing three closely related catalysts, CME scientists established that hydrogen production speed and efficiency are influenced by the molecules' structure and proton relay arrangement, not the total number relays.
How to Store Sunlight on a Tight Energy Budget: Add More Protons
Making hydrogen economically demands a quick, efficient reaction. Creating that reaction demands a catalyst. CME scientists found that a proton and water-packed environment lets the catalyst work 50 times faster—without added energy.
Adventure Planning, Catalyst Style
At PNNL, scientists have elaborated on a strategy to map the catalytic route. Scientists can now explore design decisions with molecular catalysts that store or release energy from the chemical bond in dihydrogen (H2).
