One-Pot Synthesis of Potassium-Functionalized Mesoporous γ-Alumina: A Solid Superbase

Basically super: Potassium‐functionalized mesoporous γ‐alumina solid superbases that have a high base strength (H−) of 27.0, a well‐expressed mesoporous structure, and which are efficient in the isomerization of 1‐hexene are synthesized by a one‐pot method. The success of this method can be ascribed...

Zusammenfassung:Basically super: Potassium‐functionalized mesoporous γ‐alumina solid superbases that have a high base strength (H−) of 27.0, a well‐expressed mesoporous structure, and which are efficient in the isomerization of 1‐hexene are synthesized by a one‐pot method. The success of this method can be ascribed to the flexible application of K2CO3 as a pH adjustor and close control of the calcination process (see picture).
