Ph.D Thesis Title

“Synthesis and Characterization of Spinel Oxide

Nanoparticles towards Environmental Remediation”

Ph.D Thesis Abstract

AB2O4 structure-based oxide are a class of semiconductor metal oxides that have been proved as promising material for photocatalysis. It scores over others because of its unique crystal structure properties with suitable bandgap for photodegradation process. In the present work, we focused on doped aluminate

(ZnAl2-xMxO4 (M = Bi & Ce), CuAl2-xMxO4 (M = Bi & Ce)) and co- doped ferrite (Co1-yCuyFe2-xMxO4 (M = Bi & Ce) and Zn1-yCuyFe2- xMxO4 (M = Bi & Ce)) nanoparticles synthesized by co-precipitation and solution combustion method respectively. The prepared nanoparticles were characterized by different instruments such as powder XRD, FT-IR, UV-DRS, SEM-EDAX, TEM, XPS and VSM analysis. The doped aluminate and co-doped ferrite nanoparticles have shown low crystalline size and low band gap energy compared to undoped nanoparticles. Photocatalytic performance of un-doped and doped aluminate (ZnAl2O4, ZnAl1.95Bi0.05O4, ZnAl1.90Bi0.10O4, ZnAl1.99Ce0.01O4, ZnAl1.98Ce0.02O4, CuAl2O4, CuAl1.99Bi0.01O4, CuAl1.97Bi0.03O4, CuAl1.95Bi0.05O4, CuAl1.99Ce0.01O4, CuAl1.97Ce0.03O4 and CuAl1.95Ce0.05O4) nanoparticles were tested by performing the decomposition of organic pollutants such as Methylene blue and Rhodamine B under UV and Visible light irradiation. Catalytic activity of doped and co-doped ferrite (CoFe2O4, Co0.5Cu0.5Fe2O4, CoFe1.95Ce0.05O4, CoFe1.90Bi0.10O4, Co0.5Cu0.5Fe1.90Bi0.10O4, Co0.5Cu0.5Fe1.95Ce0.05O4, ZnFe2O4, Zn0.5Cu0.5Fe2O4, ZnFe1.95Ce0.05O4, ZnFe1.90Bi0.10O4, Zn0.5Cu0.5Fe1.90Bi0.10O4 and Zn0.5Cu0.5Fe1.95Ce0.05O4) nanoparticles were studied for the degradation of Bisphenol A under UV-light irradiation. It was noticed from the results that doped aluminate and co-doped ferrite nanoparticles had shown high photocatalytic performance than undoped counterparts. The photocatalytic activity of selected doped aluminate (ZnAl1.90Bi0.10O4, ZnAl1.98Ce0.02O4, CuAl1.97Bi0.03O4 and CuAl1.97Ce0.03O4) and co-doped ferrite (Co0.5Cu0.5Fe1.90Bi0.10O4, Co0.5Cu0.5Fe1.95Ce0.05O4, Zn0.5Cu0.5Fe1.90Bi0.10O4 and Zn0.5Cu0.5Fe1.95Ce0.05O4) nanoparticles were studied using Rhodamine B under visible irradiation to identify the efficient catalyst among the synthesized compounds. Among all compounds, Co0.5Cu0.5Fe1.95Ce0.05O4 nanoparticles have shown maximum photocatalytic performance towards the degradation of Rhodamine B.

copper and cerium in zinc ferrite on the

photocatalytic degradation of bisphenol

Highlights: In the current research,

undoped, doped and co-doped

ZnFe2O4 magnetic nanoparticles were

synthesized to remove the BPA

degradation of BPA using

Zn0.50Cu0.50Fe1.90Bi0.10O4 and

Zn0.50Cu0.50Fe1.95Ce0.05O4 nanoparticles

were 90.09 and 91.25% in 180 min with

the rate constant of (k) 0.02250 and

0.02365 min−1, respectively. The

reactive species responsible for

photocatalytic degradation were

hydroxy radicals and superoxide
