In this study a novel approach for the synthesis of nano-Silica and Zeolite-Y is described. Nano-Silica was effectively prepared from bamboo (Bambusa Vulgaris) leaves ash. Zeolites are Sodium Aluminosilicates. The synthesized nano-Silica was employed in the preparation of zeolite-Y which showed better results in the photo catalytic degradation of Azo dyes: Methyl orange and Methylene blue. The following characterisations were performed: UV-VIS, FT-IR, SEM, TG-DTA and XRD. The photo catalytic degradation was carried out by varying contact time, pH, initial dye concentration and the percentage efficiency was calculated. Thus this work is a clear enclosure of the synthesis, characterisation and applications of bothnano-Silica and zeolite-Y.
