Synthesis of nanoparticles will be done using two simple methods: Mycogenic and Microwave method. For mycogenic method, synthesis of Gold (Au), Platinum (Pt), Palladium (Pd), Nickel (Ni), Copper (Cu), and Zinc (Zn) nanoparticles (NP) using the following fungi: Aspergillus niger, Trichoderma reesei, and Trichoderma viride, which are known to release enzymes extracellularly, will be done. Different concentrations of metal ion solutions will be added to filtrates from different fungal sources and will be left to stand for 1-4 days. Synthesis of the different metal NP is then expected. The effect of varying metal ion concentration and type of fungi on the shape and size distribution of synthesized NP will then be determined. For microwave method, Perovskite-Type nanoparticles with chemical formula LnFeO3 and LnCoO3 (where Ln =Gd, Ce, Pr) will be synthesized through microwave irradiation of precursor compounds Ln[Fe(CN)6] and Ln[Co(CN)6). A strong UV absorber CuO will be used to enhance the degradation of the said precursor compounds. Nanoparticles: GdFeO3, CeFeO3, PrFeO3, GdCoO3, CeCoO3, and PrCoO3 is expected be synthesized. The effect of varying the microwave power and heating time on the morphology and size distribution of the synthesized NP will be investigated. Resulting nanoparticles will then be characterized by UV-VIS, FT-IR, EDX, XRD, SEM, and TEM. Lastly, an example application of NP will be tested, using the microwave synthesized perovskite-type NP. The synthesized Perovskite-type and by using it as catalyst in the photodegredation of Rhodarnine B.
