大比表面积大孔体积氧化铝的制备进展

Progresses in synthesis of alumina with large specific surface area and pore volume

综述了大比表面积大孔体积的氧化铝的制备方法及其进展,包括醇铝水解法、热分解法、偏铝酸钠CO2中和法、有机溶剂法、有机模板剂法和无模板剂法等。通过对氧化铝的比表面积和孔体积等性质的讨论,展望了未来大比表面积大孔体积氧化铝的研究方向,指出无模板剂法的合成原料廉价易得、合成方法简便快捷、合成过程绿色环保,是未来发展的方向。

Several methods,namely hydrolysis of aluminum isopropoxide,thermal decomposition,Na Al O2-CO2 neutralization,method using organic solvents as reaction media,template method,template-free method,etc.,for the synthesis of alumin a with large specifi c surface area and pore volume and their progresses were introduced. The specifi c surface area and pore volume of alumina synthesized by the methods were discussed. It was predicted that,the template-free method with cheap aluminous materials without any organic surfactants would be a research trend in the future.
