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 ...

Researchers probe hydrogen bonds using new technique

Researchers at Carnegie Mellon University have used nuclear resonance vibrational spectroscopy to probe the hydrogen bonds that modulate the chemical reactivity of enzymes, catalysts and biomimetic complexes. The technique ...

New catalyst material produces abundant cheap hydrogen

QUT chemistry researchers have discovered cheaper and more efficient materials for producing hydrogen for the storage of renewable energy that could replace current water-splitting catalysts.

Light-activated, single-ion catalyst breaks down carbon dioxide

A team of scientists has discovered a single-site, visible-light-activated catalyst that converts carbon dioxide (CO2) into "building block" molecules that could be used for creating useful chemicals. The discovery opens ...

Microgel powder fights infection and helps wounds heal

While making smart glue, a team of engineers discovered a handy byproduct: hydrogen peroxide. In microgel form, it reduces bacteria and virus ability to infect by at least 99 percent.
