Greener hydrogen from water

The idea of using hydrogen as the basis of a clean sustainable energy source, often termed a hydrogen economy, has been a topic of conversation for decades. Hydrogen fuel, for example, doesn't emit any carbon dioxide and ...

Illuminating nanoparticle growth with X-rays

Hydrogen fuel cells are a promising technology for producing clean and renewable energy, but the cost and activity of their cathode materials is a major challenge for commercialization. Many fuel cells require expensive platinum-based ...

'Frozen' copper behaves as noble metal in catalysis: study

As a non-noble metal, copper oxidizes more easily to a positive valence (Cu+ or Cu2+) than same-family elements Au or Ag. In general, this chemical property is mainly determined by electron structure. Can we change the chemical ...

From a plant sugar to toxic hydrogen sulfide

In a doctoral research project conducted at the Department of Biology, researchers have described the degradation of the dietary sugar sulfoquinovose by anaerobic bacteria to toxic hydrogen sulfide for the first time—increased ...

A newly discovered catalyst promises cheaper hydrogen production

A new catalyst could dramatically decrease the cost of producing hydrogen, one of the cleanest renewable fuels. Based on molybdenum sulfide, the catalyst was developed by a group at the A*STAR Institute of Materials Research ...

Preventing concrete bridges from falling apart

Extremes of temperature, rain, exposure to corrosive substances—all of these environmental factors contribute to the degradation of concrete. Specifically, a gas present in our environment, called hydrogen sulphide, turns ...
