Abstract
In this report, an easy and facile approach for the fabrication of heterogenous, mesoporous nanostructure of graphitic carbon grafted with silane (AEAPTMS) and modified with nanoparticles of Ce and Ag, (Ag,Ce@SNC/A1SCA). The graphitization in carbon was induced by ionic liquid-assisted reaction between the glucose and ethylenediamine under mild conditions. It was characterized by thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET), powder X-ray diffraction study (PXRD), ultraviolet–visible spectroscopy (UV-VIS), high-resolution transmission electron microscopy (HRTEM), field emission gun-scanning electron microscopy (FEG-SEM), elemental mapping, X-ray photoelectron spectroscopy (XPS), photoluminescence (PL), inductively coupled plasma atomic emission (ICP-AES) and fourier transform infrared spectroscopy (FT-IR). Its acts as an adaptable heterogeneous nanocatalyst in the formation of 3,4-disubstituted isoxazol-5(4H)-one and polyhydroquinoline derivatives. It displayed recyclability for five runs. The recycled catalyst was characterized by PXRD and XPS analysis. XPS analysis established the synergism between metal nanoparticles of Ag and Ce in the prepared nanomaterial.
