摘要: Abstract In this work, we first prepared titanium-modified hybrid periodic mesoporous organosilicas (Ti-modified PMOs) by direct synthesis from co-condensation of 1,2-bis(triethoxysilyl)ethane (BTESE) and titanium isopropoxide (Ti) using cetyltrimethylammonium bromide as a structure directing agent. X-ray diffraction (XRD) patterns transmission electron microscopy images showed well-defined hexagonal symmetry mesopore structures for the Ti-modified PMOs. The pore was maintained up to loading 0.3 mole ratio Ti/BTESE. UV–Vis spectra indicated successful incorporation into PMOs, which is also supported photoelectron (XPS). surface area diameter were reduced with increasing titanium.
