Title: Metallic nanoparticle-doped IRFA@SiO2 catalyst using iron-rich fly ash and preparing method of the same
Inventor: BAE SUNG JUN
IPC: B01J35/00

Granted: 2021-02-16
Abstract: The present invention relates to development of a novel Pd-doped IRFA@SiO_2 (Pd/IRFA@SiO_2) catalyst capable of improved reduction of para-nitrophenol (p-NP), which includes preparation of an IRFA@SiO_2 composite from coal fly ash (CFA) as a starting material. Since Pd shows excellent catalytic activities to hydrogenation and C-C coupling reaction, it is selected as noble metal nanoparticles. The physical and chemical properties of Pd/IRFA@SiO_2 are determined by high-resolution field-emission scanning electron microscopy (HR-FESEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffractometry (XRD), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) adsorption analysis, magnetic force analysis, zeta-potential analysis, or the like. Finally, effects of important factors (i.e. Pd loading, NaBH_4 concentration and catalyst loading) upon NP reduction and recyclability are determined. The novel catalyst according to the present invention can be applied to additional processing of CFA into a high added-value material and high-efficiency treatment of industrial waste water containing p-NP.
