Photocatalytical Properties of Bismuth Oxide films.


Knowledge and experience in materials science, chemistry, and chemical engineering in general and photocatalysis systems in particular. During and after my M.Sc. research, I have been working in some international research projects (BISNANO and PHOCSCLEEN) dealing with thin films for photocatalytic applications. During my research stay in Politecnico di Torino (Italy), I have learned some photoelectrochemical techniques to study the photocatalytic activity of some materials such as Bi2O3 and TiO2.

My areas of interest are: thin films deposition, photoelectrochemical tests, water remediation, hydrogen production, optical properties and surface characterization. I am seeking new and challenging opportunities for using my knowledge and experience for the benefit of the society.

In my free time I like to take some landscape photographs but my real passion is the running, I have done four half marathons and the next step is the complete marathon. Moreover, my goal in the future is to do the Ironman.
