Multimetal nanoframes improve catalyst performance

A team of researchers has synthesized a highly active and durable class of electrocatalysts by exploiting the structural evolution of solid Pt-Ni bimetallic nanocrystals into porous cage-like structures or nanoframes. This ...

Aerogel catalyst shows promise for fuel cells

(Phys.org)—Graphene nanoribbons formed into a three-dimensional aerogel and enhanced with boron and nitrogen are excellent catalysts for fuel cells, even in comparison to platinum, according to Rice University researchers.

Researchers bring clean energy a step closer

For nearly half a century, scientists have been trying to replace precious metal catalysts in fuel cells. Now, for the first time, researchers at Case Western Reserve University have shown that an inexpensive metal-free catalyst ...

Stretching oxides to modulate electrochemical properties

Solid oxide fuel cells and solid oxide electrolysis cells hold the promise of highly efficient energy conversion, with lower pollution, to meet increasing global energy demands. But these devices need good catalysis to speed ...

Cheap hybrid outperforms rare metal as fuel-cell catalyst

(Phys.org) —Graphene quantum dots created at Rice University grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, making them better ...

Chromium's bonding angles let oxygen move quickly

By taking advantage of the natural tendency of chromium atoms to avoid certain bonding environments, scientists at DOE's Pacific Northwest National Laboratory have generated a material that allows oxygen to move through it ...
