Chabazite Synthesis and Its Exchange with Ti, Zn, Cu, Ag and Au for Efficient Photocatalytic Degradation of Methylene Blue Dye.

A chabazite-type zeolite was prepared by the hydrothermal method. Before ion exchange, the chabazite was activated with ammonium chloride (NHCl). The ion exchange process was carried out at a controlled temperature and constant stirring to obtain ion-exchanged chabazites of Ti chabazite (TiCHA), Zn chabazite (ZnCHA), Cu chabazite (CuCHA), Ag chabazite (AgCHA) and Au chabazite (AuCHA).
