To　obtain　high-surface-area　porous　γ-Al2O3,　the　alco-hydrothermal　method　was　adopted　to　synthesize　plate-shaped　wormhole-like　mesoporous　γ-Al2O3　particles　with　a　face-centered　cubic　crystal　structure,　and　characterized　the　physical　properties　of　these　materials　by　means　of　the　X-ray　diffraction,　N2　adsorption-desorption,　scanning　electron　microscopy,　transmission　electron　microscopy,　and　selected　area　electron　diffraction　techniques.　It　has　been　shown　that　mesoporous　γ-Al2O3　particles　with　the　wormhole-like　morphology　and　good　crystalinity　can　be　fabricated　with　aluminum　tri-sec-butoxide　as　the　aluminum　source,　1-propanol　aqueous　solution　as　the　solvent,　and　lauric　acid　as　the　template　(the　mass　ratio　of　aluminum　tri-sec-butoxide　to　lauric　acid　=　4:1).　The　surface　area　of　the　Al2O3　sample　obtained　at　600C　calcination　was　up　to　306　m2/g　and　its　average　pore　diameter　was　ca.　5　nm.
