The College of Education for Pure Sciences Discusses a Master’s Thesis on Hydrothermal Synthesis, Characterization, and Photocatalysis of Silver Iodide and Tin Oxide Nanoparticles.
The Chemistry Department at the College of Education for Pure Sciences, University of Kerbala, discussed a Master’s thesis entitled “Hydrothermal Synthesis, Characterization, and Photocatalysis of Silver Iodide and Tin Oxide Nanoparticles and the Study of Some Dyes under Visible Light Irradiation.”
The thesis was presented by student Hadeel Ahmed Kadhim Al-Ghazi, under the supervision of Prof. Dr. Hamida Eidan Salman.
The study aimed to prepare nanoparticles of a nanocomposite (tin oxide and silver iodide) using hydrothermal decomposition and to use them as a catalytic surface for removing anionic (nigrosine) and cationic (malachite green) dyes, respectively. The study also investigated the photocatalytic activity under different conditions, such as the effect of dye concentration, the effect of nanocomposite weight, the effect of solvent, and the effect of sample regeneration processes.
The study concluded that the hydrothermal method proved effective in synthesizing AgI/SnO2 nanocomposites. The resulting AgI/SnO2 nanocomposites exhibited good photocatalytic activity, and the results showed that the photocatalytic activity of the binary nanocomposites significantly increased the removal rate of MG dye compared to N dye. The nanocomposite surface appeared to be well-stabilized and could be reactivated after three cycles.
The study recommended further developing the properties of SnO2 by loading different metals onto the AgI/SnO2 surface, such as palladium, platinum, and cobalt, and then investigating the properties of the resulting nanoparticles. It also recommended investigating the ability of the AgI/SnO2 nanocomposites to absorb different dyes by incorporating various metals and semiconductors. The study focused on preparing AgI/SnO2 nanocomposites using the sol-gel method and then loading the metals onto their surface via photodeposition, microwave deposition, and physical vapor deposition.
