Organotemplate-free synthesis of hollow Beta zeolite supported Pt-based catalysts for low-temperature ethanol steam reforming

A novel platinum-encapsulated hollow Beta zeolite (Pt@HBS) catalyst was successfully fabricated through an organotemplate-free and seed-directed route, with carbon spheres as a hard template. Pt@HBS not only exhibited excellent catalytic performance, but could also maintain the catalytic reaction for more than 28 h without losing its activity.
