The research led by U of A chemistry professor Steven Bergens targeted the organic compounds known as amides, which are raw materials used by many industries to make a variety of chemical products. Bergens and his research team found that combining hydrogen with their new catalyst transforms amides into a variety of desired chemical products efficiently, safety and without potentially environmentally dangerous waste.
The new catalyst is considered to be green because it produces no by-products and it uses hydrogen that can be produced easily by any industry on site. Any excess hydrogen remaining after the reaction can be reused or simply burned to generate water and heating energy. In contrast, the current, conventional method used by industry requires expensive and dangerous shipping of tons of highly flammable, reactive chemicals by truck or rail, and it also produces large amounts of waste that must be removed at added cost and threat to the environment.
Researchers around the world have been working for more than 50 years to find a catalytic system for this vital class of reaction that operates efficiently and produces little to no waste.
Currently industries such agrochemicals and pharmaceuticals must ship huge quantities of highly reactive and flammable chemicals for mass production of their products. The waste produced is expensive to process and can be hazardous to the environment.
Bergens says the discovery of a cheap catalyst with minimal and re-useable waste has the potential to revolutionize the chemical industry from an economic and green perspective.
The work of Bergens and U of A graduate student Jeremy John was published in the journal Angewandte Chemie.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
