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.
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).
Advantage: Water
When water comes in for a landing on the common catalyst titanium oxide, it splits into hydroxyls just under half the time. Water's oxygen and hydrogen atoms shift back and forth between existing as water or hydroxyls, and water has the sli
The University of Guam and PNNL Collaborate to Generate Clean Energy from the Sea
Harnessing the sea for decarbonized energy is the focus of a new collaboration between PNNL and the University of Guam.
Designing Catalysts with Pendant Amines
To design catalysts for fuel cells and other devices, design their ligands to facilitate the movement of protons, according to Dr. Daniel DuBois and Dr. Morris Bullock at PNNL.
Water Research Earns INCITE Supercomputer Access
The project received an Innovative and Novel Computational Impact on Theory and Experiment (INCITE) award, a highly competitive U.S. Department of Energy Office of Science program.
Uncovering the Details of Proton Relays Vital to Creating New Catalysts for Energy Storage
In their invited review for Chemical Communications, Dr. R. Morris Bullock, Dr. Aaron Appel, and Dr. Monte Helm at PNNL describe how proton relays and other factors influence the catalysts that produce the desired chemical bonds.
