Abstract：

The　mesoporous　γ-alumina　samples　were　synthesized　by　the　sol-gel　method　with　P123　as　the　structure　directing　agent　and　different　structural　organic　compounds　as　the　interfacial　protectors,　such　as　phenylamine　(PA),　o-phenylenediamine　(OPDA),　p-aminobenzoic　acid　(PABA),　benzoic　acid　(BA)　and　o-phthalic　acid　(OPA).　The　results　revealed　that　the　functional　group　of　interfacial　protector　had　great　impact　on　the　ordered　structure　and　thermal　stability　of　mesoporous　γ-alumina.　Among　those　interfacial　protectors,　the　use　of　the　PABA　or　OPA　could　shape　the　ordered　mesoporous　structure,　which　was　related　to　the　specific　structure　of　interfacial　protector.　The　possible　mechanisms　about　the　formation　of　the　ordered　mesoporous　alumina　have　been　also　explored,　which　will　provide　the　theoretical　guidance　for　choosing　the　suitable　interfacial　protector.　©　2012　Elsevier　B.V.　All　rights　reserved.
