DOI: 10.1134/s1070427217060179
Abstract: Two groups of niobium-containing hexagonal mesoporous silica (Nb-HMS) samples were prepared hydrothermally using niobium oxalate and niobium ethoxide as Nb source, respectively. The samples were characterized by XRD, N2-adsorption, ICP-AES, UV-Vis, respectively. They were also… read more here.
