Research on Synthesis of Mesoporous Alumina Based on Utilization of Red Mud

A novel green controlled synthesis method is proposed in this paper. Mesoporous alumina was prepared by using sodium aluminate extracted from red mud as an aluminum source. The influence mechanism of temperature, template agent and concentration on MA properties studied systematically. results show that the mesoporous γ-alumina has a good catalytic activity short-range arrangement, medium acidity, narrow pore size distribution, thermal stability hydrothermal stability. This economical can also be used to prepare other or porous materials.
