TANDEM CATALYSIS

Two become one

Nature Materials volume 21, pages 492–493 (2022)Cite this article

Subjects

Double-shelled hollow spheres comprising of different catalytic materials are shown to enhance the efficiency of catalytic processes for the selective conversion of hydrogen and carbon monoxide to gasoline.

Catalysis lies at the heart of many processes for sustainable energy, fuels and chemicals production. Often, a number of catalytic processes are required to obtain the desired product and product properties. An elimination of process steps or chemical reactors respectively can result in greatly improved process economics. An elegant way to achieve this can be via the design of a multifunctional catalytic material, which promotes more than one catalytic reaction1,2,3.
