摘要: In this study, we report a simple in situ auto-reduction strategy for the fabrication of Ag@FDU-15 nanocomposites, which small sized Ag nanoparticles are monodispersed channels FDU-15 ordered mesopolymers. The as-prepared nanocomposites were characterized by and wide angle X-ray diffraction (XRD), nitrogen sorption, thermo-gravimetric analysis (TGA), energy dispersive spectroscopy (EDS), photoelectron (XPS), transmission electron microscopy (TEM) scanning (STEM). TEM results show that silver uniformly dispersed with mean diameter 5.6 ± 0.5 nm. When used as hydrogenation catalyst, exhibit excellent catalytic performance reusability reduction 4-nitrophenol (4-NP) presence NaBH4.
