Reducing platinum need for electrocatalysts

Promising results obtained with a new electrocatalyst


Platinum is a very expensive metal and it is therefore one of the bottlenecks hindering the growth of renewable energy. Platinum is used as the catalyst in electrolysers that store electric energy as chemical compounds, and it also plays an important role in fuel cells, catalytic converters and ...

Carbon dots dash toward 'green' recycling role


Graphene quantum dots may offer a simple way to recycle waste carbon dioxide into valuable fuel rather than release it into the atmosphere or bury it underground, according to Rice University scientists. Nitrogen-doped graphene quantum dots (NGQDs) are an efficient electrocatalyst to make complex ...

Transforming Carbon Dioxide into a Key Industrial Ingredient


Carbon dioxide doesn’t have a very positive image, as it is generally only considered to be a greenhouse gas. But scientists involved in the German Government-funded eEthylen project expect their research to yield important insights into how CO2 can be efficiently converted into ethylene, thus ...


Better catalysts make better fuel cells

Electricity-powered molecular catalysts that may prove vital for a new generation of fuel cells designed.


Yale chemists have created a framework for designing electricity-powered molecular catalysts that may prove vital for a new generation of fuel cells. Also called electrocatalysts, these substances boost the rate of a chemical reaction by decreasing the energy input along the way. In fuel cells, ...


Carbon leads the way in clean energy


Groundbreaking research at Griffith University is leading the way in clean energy, with the use of carbon as a way to deliver energy using hydrogen. Professor Xiangdong Yao and his team from Griffith's Queensland Micro- and Nanotechnology Centre have successfully managed to use the element to ...
