Catalytic Ability of Ag-coated Ferromagnetic Microspheres Functionalized by TiO2

TiO2 has been used to clean wastewater as a photocatalyst that catalyzes the decomposition of organic pollutants through the production of reactive oxygen species. TiO2 has previously been functionalized on Fe3O4 for improved recyclability of the nanoparticles, and Ag-coating is applied to enhance nanoparticle’s catalytic ability by reducing the bandgap of the catalyst in other researches. In my research, I performed an experiment and will present a way of synthesizing Fe3O4@AgNPs@TiO2 microspheres by functionalizing the ferromagnetic microspheres with silver nanoparticles before TiO2. A photocatalytic test on the decomposition of methyl blue will also be performed to determine the catalytic ability of the obtained microspheres.
