Double-layer hollow spheres catalyse syngas conversion into clean fuels

Researchers have engineered a nested catalyst that combines the best of both metal oxide and zeolite catalysts, turning carbon monoxide and hydrogen directly into liquid hydrocarbons . Its unique layered structure maximises performance and selectivity for liquid hydrocarbons, particularly the traditional ingredients of petrol.

‘Tandem catalysts with metal oxides and zeolites already existed,’ explains lead author Bert Weckhuysen from Utrecht University in the Netherlands. However, their structure and architecture are often random – a result of the processes used in their fabrication. ‘Our controlled synthesis yields double-shelled hollow spheres with great possibilities.’ Among other things, the layered arrangement facilitates the different stages of the step-by-step conversion of syngas into fuels.
