title: Microporous Crystalline γ-Al2O3Replicated from Microporous Covalent Triazine Framework and Its Application as Support for Catalytic Hydrolysis of Ammonia Borane.
abstract: Significant progress has been made on the synthesis and application of mesoporous γ-alumina. To date, little attention has been paid to the synthesis of microporous crystalline alumina. Here, fabrication of microporous crystalline γ-alumina using a microporous covalent triazine framework (CTF-1) as a template is described. Microporous crystalline γ-alumina with a micro-meso binary pore system was replicated by infiltration of aluminum nitrate into the micropores of the CTF-1 template through a NH3/water-vapor-induced internal hydrolysis method, followed by thermal treatment, and subsequent removal of the CTF-1 template with a 30 % H2O2aqueous solution. The obtained crystalline γ-alumina material exhibits a large surface area (349 m2g-1) with micropore distribution centered at about 1.27 nm. Ru supported on microporous γ-Al2O3can be employed as catalyst for hydrolytic dehydrogenation of ammonia borane, and it exhibits high catalytic activity and good durability. This finding provides a new benchmark for preparing well-defined crystalline microporous alumina materials by a template method, which can be applied in a wide range of fields.
