Structural and thermal stability of mesoporous alumina synthesized by Al-based coordination polymer

Mesoporous alumina with a narrow pore size distribution is synthesized by direct thermolysis of Al-based coordination polymer. By applying the appropriate thermolysis temperature, both high surface area and large pore volume are obtained with the collapses and elimination of the 1,4-benzenedicarboxylate linkers of Al-based coordination polymer. This new class of mesoporous alumina display better adsorption properties and higher thermal stability, which retain mesoporous properties and high surface area after calcination in 900   °C. This thermolysis method provides a new approach to synthesize mesoporous alumina with high thermal stability by using coordination polymers.
