One-step-impregnation hard templating synthesis of high-surface-area nanostructured mixed metal oxides (NiFe2O4, CuFe2O4 and Cu/CeO2).
We report here on an efficient one-step-impregnation method to synthesize crystalline mesoporous bimetal oxides (e.g. NiFe(2)O(4), CuFe(2)O(4), Cu/CeO(2)) using mesoporous silicas as hard templates under optimized mixing conditions. This new procedure enables a true replication of the mesostructure with high yield and phase purity, while retaining particle morphology of the template.
متن کاملHigh surface area and Z' in a thermally stable 8-fold polycatenated hydrogen-bonded framework.
1,3,5-Tris(4-carboxyphenyl)benzene assembles into an intricate 8-fold polycatenated assembly of (6,3) hexagonal nets formed through hydrogen bonds and π-stacking. One polymorph features 56 independent molecules in the asymmetric unit, the largest Z' reported to date. The framework is permanently porous, with a BET surface area of 1095 m(2) g(-1) and readily adsorbs N2, H2 and CO2.
متن کاملTemplate Synthesis of High Surface Area Metal Oxides . Example : An Excellent Structured Fenton - like Catalyst
Standard sacrificial template synthesis allows metal oxide nanotubes to be produced from ZnO nanowires. In spite of their high interest in several technological fields, the low surface area of these nanotubes is a drawback for most applications. Here we report for the first time the sacrificial template synthesis of stainless steel wire-mesh (SSWM) supported metal oxides of high technological i...
متن کاملPreparation of High Surface Area ZrO2 Nanoparticles
In comparison to the previous researches, ZrO2 nanoparticles with higher surface area (85 m2/g) have been synthesized in this research. The as-prepared ZrO2 nanoparticles by co-precipitation method were characterized with X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The surface area of the s...
متن کاملAn Alternative Method for Synthesis of Thermally Stable Aromatic Polyesters Containing Schiff Base Unites
In this paper, an efficient method for synthesis of aromatic polyesters containing schiff base units is described by preparation of two polyesters. These polyesters have been prepared by the reaction of terephthaloyl dichloride on Schiff bases derived from p-hydroxybenzyldehyde and 4,4-diamino diphenyl ether, 4,4-diamino diphenyl methane. The Polymers were characterized by IR, CHNS, thermal...
