dc.description.abstract | Morphology oriented synthesis of metal oxide doped silica structures have fascinating properties which needed to be explored extensively. In this work, NiO doped silica microsphere with beautiful flower-like morphology has been achieved by adopting a facile surfactant-assisted synthetic route using CTAB-ammonia in H2O–ethanol mixed solvent media. The sol–gel synthesis with effective variations of Ni/Si ratios up to 7.0, followed by a simple hydrothermal treatment and subsequent calcination leads to the formation of NiO–silica mesostructures with high nickel content. Detailed structural and elemental characterizations by using powder X-ray analysis (XRD), scanning electron (SEM) and transmission electron microscopy (TEM), N2 adsorption–desorption, X-ray photoelectron spectroscopy (XPS) revealed that single cubic phase NiO doped mesoporous silica microspheres (for Ni/Si = 5:1 and 7:1) with good surface area (169 and 205 m2 g−1 for sample with Ni/Si = 7:1 and 5:1, respectively) and pore width 3–5 nm, have been formed with 3D flower-like shape and 500–600 nm particle size. These NiO–silica microspheres containing high Ni content up to 76 wt% have shown excellent paramagnetic properties at room temperature. © 2019 | - |
