Tailored ordered porous alumina with well-defined and uniform pore-structure

► Welldefined and uniform pore-structure (WDUPS) Al2O3 was prepared. ► The pore-size of the prepared WDUPS Al2O3 can be tailored. ► The acid properties of the WDUPS Al2O3 is the same to that of conventional γ-Al2O3. ► The WDUPS Al2O3 is an ideal material for fundamental research in catalysis.
