Mesoporous Nanotubes of Iron Phosphate: Synthesis, Characterization, and Catalytic Property

摘要: Iron phosphate nanotubes with mesoporous walls are solvothermally synthesized using sodium dodecyl sulfate (SDS) as a template. With different template concentrations, various shapes of nanosized iron phosphates can be obtained. When the concentration SDS is set at transition regions between lamellar and hexagonal mesophases, according to its phase diagram, coassembly precursor forms flake-type phosphate. Otherwise, nanoparticles or bulky sheets The followed solvothermal treatments on flakes produce walls. removal surfactant by acetate exchange heat treatment results in clean diameters 50−400 nm lengths several microns. nanotubular possesses specific surface area 232 m2/g bimodal distribution pore sizes, corresponding t...
