拟薄水铝石孔结构调控的研究进展

Research progress in control of pore structure of pseudo-boehmite

综述了近年有关拟薄水铝石孔结构调控的国内外文献,指出控制合成条件、添加助剂和模板剂可有效改善拟薄水铝石的孔结构,即在合适的pH和温度下进行合成可抑制三水铝石、湃铝石等杂质产生,添加硅、磷等助剂可改变拟薄水铝石的晶体结构,而模板剂可促使拟薄水铝石微晶沿特定方向生长。

The literatures at home and abroad in recent years on controlling the pore structure of pseudo-boehmite are reviewed.It is pointed out that the pore structure of pseudo-boehmite can be effectively improved by controlling the synthesis conditions,adding auxiliaries and templates,namely the synthesis under suitable pH and temperature can inhibit the formation of the impurities such as gibbsite,bayerite and so on,the crystal structure of the pseudo-boehmite can be changed by adding the auxiliaries such as silicon,phosphorus and so on,and the template can promote the growth of the pseudo-boehmite microcrystal along the specific direction.
