Abstract
Metal oxide - aluminophosphate composite was synthesized using Zinc nitrate employing the whole plant extract of Parmelia perlata, lichen using a green synthetic method.. Whole-plant extracts of Parmelia perlata was used as an oxidizing agent to oxidize metal nitrates into corresponding oxides on the surface of aluminophosphate zeolites yielding metal oxide-aluminophosphate composites. The structure and composition of the synthesized MO-AlPO composites were confirmed by XRD, FT-IR, SEM-EDAX, HR-TEM, BET, and TGA. The surface area of the ZnO-AlPO composite was found to be 21.193 m2/g with pore volume 0.083 cm3/g and pore diameter 12.83 nm. Synthesized ZnO-AlPO composite was evaluated for its adsorption efficiency using methylene blue as a model pollutant.
