Abstract

original image

Aerosol processing coupled with surfactant-templated sol–gel synthesis is used to produce MoO3-SiO2-Al2O3 catalysts. By quenching the sol–gel kinetics by fast drying of the aerosol, molecular-scale dispersion of each component is achieved. The structuring agent generates an organized porosity at the nanoscale. The catalysts have a high specific surface area and outstanding olefin metathesis activity.
