Abstract:

A mesoporous molecular sieve MCM-41 dimensional hexagonal arrangement has a diameter of 2-10 nm, thermal stability, high pore volume and high surface area. In the synthesis of MCM-41 is used as the CTMABr directing agent and tetraethyl orthosilicate (TEOS) as silica source. Several studies have been developed using the residue of bagasse sugar cane, due to the high percentage of silica in its composition, making it a promising source for materials synthesis, favoring the use of this product impactful to the environment. This paper aims at the synthesis and characterization of MCM-41 with molar composition: 1.0 CTMABr: 4.0 SiO2: 1 Na2O: 200 H2O using waste. The materials were characterized by the techniques of X-ray Diffraction (XRD), chemical analysis by X-ray spectrometry, energy dispersive (EDX) spectroscopy and in the infrared (IR). ). By XRD and IR verified the formation of mesoporous molecular sieve MCM-41. The XRD of the as-synthesized samples MCM-41 displayed the characteristic (1 0 0) reflection of typical MCM-41, with EDX was observed high silica content in the residue of bagasse sugar cane.
