摘要
γ-Al2O3主要来源于其前驱体勃姆石(AlOOH),由于具有高的比表面积,常作为催化剂载体和吸附剂。该文以Al(NO)3·9H2O和NaOH为原料,采用溶胶凝胶法制备出了高比表面积的AlOOH,经过热处理得到丛状的多孔性γ-Al2O3。并利用X射线衍射(XRD)、场发射扫描电镜(SEM)和N2吸附-脱附技术对所得的产物进行表征。
The γ-Al2O3 was very suitable to be used as a catlalyst support and an adsorbent because of its vast surface.The γ-Al2O3with high surface area was mainly derived from its precursor boehmite （AlOOH）.The porous AlOOH was synthesized by sol-gel method using alumina nitrate and sodium hydroxide as main raw materials.The fasciculate porous alumina was obtained by heat with AlOOH treatment.And it was characterized by XRD,SEM and N2 adsorption-desorption technique.
