Enzymes inspire new catalyst design for hydrogen production
The coupled enzyme reaction is more efficient than industrial alternatives © ACS
A novel enzyme-based catalyst developed by UK and US researchers hints at new ways of designing catalysts for the water-gas shift reaction, an important industrial reaction in the production of high grade hydrogen.
The water-gas shift, which uses carbon monoxide and water to produce carbon dioxide and hydrogen, has been used in industry since the 1940s. Various metal catalysts are used, including copper and platinum, but according to Fraser Armstrong at the University of Oxford, industry could do better. His team have created an unusual catalyst in which two different bacterial enzymes are stuck to tiny pieces of graphite. More...
