【摘要】 不同形貌的勃姆石纳米材料广泛应用于各个领域,也是制备Al2O3的重要前驱体。具有特殊形貌的氧化铝因独特的孔道结构和表面性质,显示出比传统的氧化铝更加优越的吸附和催化性能,被广泛用作特种陶瓷、催化剂载体、催化剂和吸附材料等。因勃姆石在煅烧过程中原有的微观形貌保持不变,可通过煅烧不同形貌的勃姆石得到特定形貌的氧化铝纳米微晶。因此,制备不同形貌的勃姆石纳米材料是一个非常有价值的课题。对近年来国内外运用不同方法制备多种形貌勃姆石的研究结果做了综合评述和展望。更多还原

【Abstract】 Boehmite nanomaterials with various kinds of morphologies are extensively applied in different fields.They are also important precursors for the preparation of alumina nanomaterials with various morphologies.Alumina nanomaterials with special morphologies own unique pore structure and surface properties,which demonstrates more predominant adsorptive property and catalytic performance,and thus are widely used in manufacturing special ceramics,catalyst carrier,catalyst and adsorbing materials.As the original morphology of boehmite remains unchanged in calcination process,specific morphologies of alumina nanocrystals can be obtained by calcination.Therefore,the synthesis of boehmite nanomaterials with diverse morphologies is an extremely rewarding research subject.The synthesis of boehmite nanomaterials with diverse morphologies by distinct means at home and abroad in recent years is reviewed and previewed comprehensively.更多还原
