Abstract:

The Philippine natural zeolites (PNZ) were doped with zinc using ion exchange process. Calcined and un-calcined samples of zinc oxide-zeolite (ZnO-PNZ) composites were characterized by using Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM). The FTIR spectrum showed the characteristic peaks and structure of PNZ upon the incorporation of zinc oxide (ZnO). On one hand, SEM analysis confirms the formation of ZnO nanoparticles on the surface of zeolite. The calcination procedure did not alter the crystalline structure of the ZnO-PNZ composite.
