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).

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.

New Catalyst Dives into Water to Produce Hydrogen

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

Would You Hire This Catalyst?

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 Pathway for Protons

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.

Catalyst Masters Reverse

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.
