College of Engineering, University of Baghdad discussed a Ph.D. thesis on improving the photocatalytic degradation of organic dyes and pathogenic bacteria via using ZnXMn(1-X) Fe2O4@Ag-AgVO3 by postgraduate student, Ms. Nour Al-Huda Alaa Al-Din Jassim.

The thesis aimed at studying improving the efficiency of removing organic dyes using a reinforced and core/shell Nano-structure by examining the photocatalytic efficiency of these structures and analyzing the basic mechanisms of the reaction.

The thesis reviewed preparing and manufacturing various Nano-composites and testing their effectiveness in removing organic dyes such as Rhodamine B and methyl orange, with a focus on the optimal conditions for the reaction and auxiliary factors to improve performance.

The thesis demonstrated the role of electrons in the organic decomposition process by providing promising results for biological and medical applications such as reducing bacteria and killing cancer cells, while emphasizing the safety and effectiveness of the nanocomposites made.

The thesis recommended the necessity of studying the replacement of metal ferrite compounds and choosing other spike ferrites to improve performance, studying Nano-composites of reinforced and core/cortical metal ferrite and researching the use of other optically active metal ferrites, as well as the importance of studying the harmful effects of Nano-composites and improving their toxicity and effectiveness as tumor proliferative agents.
