Synthesis and properties of Nb-containing mesoporous materials with bimodal pores using TEOS and layered perovskite K2NbO3F
We synthesized Si-Nb-mesoporous materials using TEOS, layered perovskite K2NbO3F, and HDTMACl as starting materials. TEM-EDX and LR spectra measurements indicated that niobium was introduced in the silica framework, forming Si-O-Nb bond. Mesopores due to the templating effect of HDTMA formed in the nanoparticle. thus producing a bimodal mesoporous material.
