Abstract

Mesoporous alumina was synthesized from AlCl3 and NaAlO2 using methylcellulose (MC) as the template. The MC could be recycled by exploiting its phase changes with temperature, and 63.48% of the template was recovered after the synthesis. The mesoporous γ-alumina produced was in short-range order, with moderately strong acidity, a narrow pore-size distribution and a median pore diameter of 3.7 nm. The mesoporous alumina was thermally stable up to 650 °C and hydrothermally stable. Mesoporous silica was also successfully synthesized using the MC template. This economical and green synthesis could be applied to prepare other mesoporous or porous materials.

Graphical abstractMesoporous alumina was synthesized using thermo-reversible methylcellulose as template from the aqueous solution of AlCl3 and NaAlO2, and 63.48 % of the template MC could be recovered after the synthesis. The prepared alumina was confirmed with the mesoporous structure, the short-range ordered channels, the narrow pore-size distribution of median pore diameter about 3.7 nm, and the crystal phase of γ-alumina.Figure optionsDownload full-size imageDownload as PowerPoint slideResearch highlights► Mesoporous alumina was synthesized from inorganic sources using MC as template. ► The MC template was recyclable, and up to 63.48% was recovered after the synthesis. ► Mesoporous silica was also successfully synthesized using the MC template. ► This economical and green method could be used to prepare other porous materials.
