Catalytic Ability of Ag-coated Ferromagnetic Microspheres Functionalized by TiO2

TiO
₂
has been used to clean wastewater as a photocatalyst that catalyzes the decomposition of organic pollutants through the production of reactive oxygen species. TiO
₂
has previously been functionalized on Fe
₃
O
₄
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 Fe
₃
O

@AgNPs@TiO

microspheres by functionalizing the ferromagnetic microspheres with silver nanoparticles before TiO
₂
. A photocatalytic test on the decomposition of methyl blue will also be performed to determine the catalytic ability of the obtained microspheres.
