Pitches are thermoplastic and have a high carbon yield, which is the main reason why they have been commonly used in carbon industries. Gold nanoparticles unified on various materials have produced great awareness in the field of catalysis and material science. Presently, we preceded to the development of nano carbon cages (CC), carbon gold composite (CGC) and carbon gold silica (CGS) composite using template methods with nano silica ball (NSB), pyrolysis fuel oil (PFO) and 1% HAucl4 solution. Due to their easy fabrication protocols and broad potential applications, the hybrid nanocomposites CC, CGC and CGS are choosy for specific interests. Here, CC and CGC nanocomposites commonly referred to be carbon cages and gold nanoparticles deposited into carbon cages respectively. The hybrid nanocomposites was combined the excellent physical and chemical properties of gold, carbon and silica foundation. The activity and selectivity of the composites for ethylene adsorption capacity and catalytic oxidation were studied with excellent selectivity and higher conversion respectively. The composites were characterized by power X-ray diffraction (XRD), thermo-gravimetric analysis (TGA), N2 adsorption-desorption isotherm, scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS), transmitted electron microscope (TEM) and FT-IR.
