In studying how to modify carbon electrodes for catalyzed reactions, scientists at the Center for Molecular Electrocatalysis designed a process for creating a plethora of specialized electrodes at room temperature.
Few catalysts are energy efficient, highly active, stable and operate in water, but a nickel-based catalyst designed at the Center for Molecular Electrocatalysis at PNNL quickly produces hydrogen molecules in solutions with 75 percent water
In the 1001 Word Challenge, the U.S. Department of Energy invited the 46 Energy Frontier Research Centers to represent their science using cartoons, photos, and original paintings. Check out the entries, including one by CME.
Given two catalysts for the job of turning intermittent wind or solar energy into chemical fuels, scientists chose the material that gets the job done quickly and uses the least energy.
A new catalyst is faster when it and its surrounding acid have the same proton donating ability or pKa, according to scientists at the Center for Molecular Electrocatalysis, an Energy Frontier Research Center, at PNNL.
An American Chemical Society Symposium honors DuBois' contributions, including his inorganic chemistry work and his latest award, the American Chemical Society's Award in Inorganic Chemistry.
Proton delivery and removal determines if a well-studied catalyst takes its highly productive form or twists into a less useful structure, according to scientists at PNNL.
A fast and efficient iron-based catalyst that splits hydrogen gas to make electricity — necessary to make fuel cells more economical — was reported by researchers at the Center for Molecular Electrocatalysis, based at PNNL.
By grafting features analogous to those in Mother Nature's catalysts onto a synthetic catalyst, scientists at PNNL created a hydrogen production catalyst that is 40% faster than the unmodified catalyst.
Moving four relatively large protons to where they are needed is easier if you build a path, as is being done by scientists at the Center for Molecular Electrocatalysis.
When it comes to driving hydrogen production, a new catalyst built at PNNL can do what was previously shown to happen only in nature: store energy in hydrogen and release that energy on demand.
Dr. Wendy Shaw is one of 31 distinguished young researchers from the United States selected by the National Academy of Sciences to attend the first Indonesian-American Frontiers of Science symposium
Twisting and pinching slow a catalyst's ability to generate energy from hydrogen, according to scientists at PNNL's Center for Molecular Electrocatalysis.
Dr. Donghai Mei and Dr. Roger Rousseau, PNNL, and Dr. Wei-Xue Li, Dalian Institute of Chemical Physics, have organized a symposium to connect across the various divides in catalysis
Looking to nature for their muse, researchers at PNNL have used a common protein to guide the design of a material that can make energy-storing hydrogen gas.
Scientists at PNNL's Center for Molecular Electrocatalysis and Villanova University designed a nickel-based complex that more than doubled previously reported hydrogen gas production rates and increased the energy efficiency of the reaction
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.
