Preparation and Characterization of SnO2 / AC as a Novel High Surface Area Nanocatalyst

A new solid nanoparticle sorbent (SnO2 / AC) could serve as high surface area and inexpensive nanocatalyst was prepared. Many properties were characterized by SEM and UV spectroscopy. High surface area, large micro pore volume and total pore volume were found to be 571 m2 g−1, 0.4785 cm3 g−1 and 0.7267 cm3 g−1 respectively even with very high loaded ratio (60 %) of tin dioxide to Activated Carbon (SnO2 / AC). Taguchi factorial design method was used to get the maximum MB dye adsorption on the surface of SnO2 / AC nanoparticle sorbent. Contact time (60 min), initial dye concentration (5 mM) and solution temperature (293 K) were found to be the best conditions for the more effective absorption process
