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.
