Hydrothermal synthesis and characterizations of 2D and 3D 4ZnO·B2O3·H2O nano/microstructures with different morphologies

摘要

2D and 3D nano/microstructures of 4ZnO·B2O3·H2O with different morphologies have been successfully synthesized by a hydrothermal route in the presence of surfactant polyethylene glycol-300(PEG-300).Lamellar-like nanoparticles and microsphere organizations of nano and microrods are fabricated by varying the reaction conditions.The products have been characterized by XRD,FT-IR,TG-DTA and SEM.The XRD data indicate the as-prepared samples present at pure phase 4ZnO·B2O3·H2O with monoclinic symmetry.The SEM results reveal that the lamellar-like particles are about 30 nm in thickness and around several hundred nanometers in diameter.The microsphere organizations have different diameters,and the secondary structures are made from rod-like particles with different size and mode,respectively.The morphologies of products strongly depend on surfactant,hydrothermal temperature and time.
