Abstract

Feel the burn: Silica/alumina was prepared in milliseconds by flame-spray pyrolysis (see picture) with a homogeneous composition and at super-high calcination temperatures. This solid acid has tunable acidity ranging from weak or moderate to strong Brønsted acidity. This unique property makes this material versatile for desired industrial applications.
