Aalto University researchers have developed a promising graphene-carbon nanotube catalyst for the oxygen reduction reaction and oxygen evolution reaction. Fuel cells and water electrolyzers that are low cost and efficient would form the cornerstone of a hydrogen fuel based economy, one of the most promising clean and sustainable alternatives to fossil fuels. These devices rely […]

Stanford University researchers have found that squeezing a platinum catalyst a fraction of a nanometer nearly doubles its catalytic activity. The finding could lead to better fuel cells and other clean energy technologies. It does suggest it may be possible to halve the platinum expense in devices. That alone is a huge improvement. The team […]
