|We, for the first time report the development of a hybrid photocatalyst,
HAp-TiO2-ZnO by co-integrating TiO2 and ZnO into host material hydroxyapatite
(HAp). High temperature calcination of the ingredients, e.g. eggshell,
(NH4)2HPO4, TiO2 and ZnO, led to the formation of the desired photocatalyst.
The synthesized composite was characterized by different techniques, e.g.
thermogravimetric analyzer, energy dispersive X-ray, X-ray diffractometer, Fourier
transform infrared, solid state nuclear magnetic resonance spectroscopy, scanning
electron microscope and UV-visible spectrophotometer. The photocatalytic
activity of the composite was examined through the degradation of both
cationic and anionic dye, i.e. methylene blue and methyl orange, respectively.
Observed time dependent photo-degradation profiles were fairly supportive
towards its promising application as composite photocatalyst.
