Reduction of 4-nitrophenol to 4-aminophenol is carried out over nanogold doped cobalt loaded SBA 15 catalysts in aqueous solution at room temperature using alkaline NaBH4 as the reductant. XRD and FTIR analysis of the catalysts showed the existence of Co as Co3O4 spinel structure. The efficient dispersion of nanogold particles as suggested by X-ray diffraction patterns was evident from TEM photographs...
