Co-Si mesoporous aluminum silicate (CoSi MASM (n)) molecular sieves a novel catalyst for synthesis of carbon spheres (CS’s)

A special type of Co-Si mesoporous aluminium silicate molecular sieves; Co-Si MASM with Si/Al molar ratios of 25, 50, 100, 150 were synthesise by sol-gel method and has been used as a powerful catalyst for synthesize of carbon spheres (CS’s) by the catalytic chemical vapour deposition of C2H2 at 550ºC and 850ºC for 30 minutes. The obtained uniform CS’s at 550ºC and 850ºC were characterized by XRD, FTIR, Scanning electron microscopy (SEM), Transmission electron microscopy (TEM) and Raman spectroscopy.
