A modified sol–gel process with the aid of a structure-directing surfactant was employed to synthesize crystalline mesoporous Nb 2 O 5 nanoparticles under mild conditions. The XRD result revealed that the synthesized Nb 2 O 5 nanoparticles exhibit a single crystalline orthorhombic phase without any impurities. The N 2 adsorption–desorption isotherm, pore size...
Highly crystalline MgO nanoparticles with the mesoporous-assembled structure were synthesized via a modified sol–gel process with the aid of a structure-directing surfactant under mild conditions. X-ray diffraction (XRD), transmission electron microscopy (TEM), and selected-area electron diffraction (SAED) analyses revealed that the synthesized MgO possessed high crystallinity with the particle size...
