Resumo: Usando duas temperaturas distintas de síntese 120°C e 150°C, a peneira molecular mesoporosa de fase cúbica, MCM-48, foi sintetizada hidrotermicamente. Para investigar o efeito da temperatura nas propriedades estruturais dos materiais chamados de MCM-48/120 e MCM-48/150 as amostras foram caracterizadas por difração de raios-X, adsorção-dessorção de nitrogênio e análise termogravimétrica (TG). Ambas as sínteses resultaram na fase cúbica MCM-48, contudo o material sintetizado na maior temperatura mostrou melhores características texturais como maior área superficial, volume e tamanho de poros. _________________________________________________________________________________________ ABSTRACT: Using two temperatures different of synthesis, 120°C and 150°C, mesoporous molecular sieve MCM-48 were hydrothermally synthesized. To investigate the effect of temperature on the structure properties of materials denoted as MCM-48/120 and MCM-48/150 were characterized by X-ray diffraction (XRD), N2 adsorption-desorption and thermogravimetric analysis (TGA). Both samples resulted in cubic phase MCM-48, however the material synthesized at higher temperature showed better texturais characteristics as the highest surface area, pores volume and size.
