Recycling industrial waste water
Scientists at the University of Cologne discover a new method of producing hydrogen
Among other applications, the new approach can be used to recycle industrial waste water contaminated by formaldehyde to break down the contaminants whilst simultaneously generating hydrogen. With the aid of this method, it is possible to reclaim an important raw material from industrial waste water. Prechtl and his colleagues have also identified an air-stable and robust catalyst that can be employed with the technique. The researchers have already filed a corresponding patent application.
Formaldehyde is one of the most important raw materials used in chemical engineering; around 30 million tonnes of the substance are produced annually around the world. It is therefore available as a source of hydrogen in large quantities and at low cost.
