Preparation of Γ-alumina from Aluminum Aminoalkoxides
The synthesis of materials with tailored properties is one of the most active areas of material science [1, 2]. Among so many materials, γ-alumina due to the significant application in catalysis, electronic and ceramic industry has been studied extensively [3]. Various processes have been employed for the preparation of high quality alumina, including sol-gel processing from aluminum alkoxides....
متن کاملNickel-induced morphology change of mesostructured alumina with enhanced catalytic activity for selective CO methanation.
Nickel-induced morphology change of mesostructured alumina with amorphous walls to bayerite tetrahedra when treated in water, and then to γ-alumina with worm-like mesopores topologically after it was calcined at 400 °C is reported. The catalytic activity for selective CO methanation increased significantly after this treatment.
متن کاملHydrothermal synthesis of microscale boehmite and gamma nanoleaves alumina
Novel uniform single-crystal boehmite leaf-like nanosheets with high anisotropy (with a lateral size of (4.5±0.5 μm)×(9.0±1.0 μm) and a thickness of 60–90 nm) and flower-like superstructures consisting of single-crystal petals were synthesized for the first time by a simple hydrothermal method. After calcination, those boehmite structures can be transformed into single-crystal gamma-alumina nan...
متن کاملPreparation of Alumina Nanorods from Chromium-Containing Alumina Sludge
Alumina nanorods were prepared from chromium-containing alumina sludge, and the effects of doping elements, such as Cr, Fe, and Mg, were researched. The results show that the crystal transformation of alumina is restricted by the doped Cr and facilitated by the doped Fe and Mg, which is transformed from θ-Al2O3 to α-Al2O3 in the calcination process. Meanwhile, the crystal transformation of alum...
متن کاملPorous Alumina Films with Width-Controllable Alumina Stripes
Porous alumina films had been fabricated by anodizing from aluminum films after an electropolishing procedure. Alumina stripes without pores can be distinguished on the surface of the porous alumina films. The width of the alumina stripes increases proportionally with the anodizing voltage. And the pores tend to be initiated close to the alumina stripes. These phenomena can be ascribed to the e...
