Resumen
CARRIAZO, José; BARRERA, Mario y ALMANZA, Ovidio. EVALUATION OF THE PLATINUM IMPREGNATION EFFECT ON THE SURFACE AND STRUCTURE FEATURES OF A ZEOLITE Y. Rev.Colomb.Quim. [online]. 2007, vol.36, n.3, pp.361-376. ISSN 0120-2804.
The present paper shows the evaluation of texture, surface and structure changes on a zeolite Y employed in the synthesis of solids based on supported platinum. The structure features were analyzed by X-ray diffraction (XRD) whereas the texture and morphologic properties were studied from nitrogen adsorption isotherms (77K) and scanning electron microscopy (SEM). In addition, fractal dimension and adsorption potential distribution were determinedall solids. The results show that the synthesis process induces the microporosity formation, maintaining the zeolite structure and without important topographic or energetic alterations on the surface.
