Présentation :
I conduct my research in the field of physical chemistry, exploring advanced materials and their structural, optical, and electrochemical properties. My work revolves around several key areas, combining materials science, solid-state physics, and applications in environmental and biomedical fields.
Photocatalysis & Wastewater Treatment
I focus on the photocatalytic degradation of organic pollutants, particularly metronidazole and methylene blue. To enhance photodegradation efficiency, I design and characterize doped semiconductor materials, such as Ag-STO and BiFeO₃. I also study the impact of physicochemical parameters, such as pH and adsorption, and explore charge transfer mechanisms, particularly the Z-scheme and S-scheme, which improve charge carrier separation.
Synthesis and Characterization of Nanomaterials & Nanocomposites
I work on the green synthesis of nanomaterials, including the fabrication of Ni/NiO nanorods using Nigella sativa extracts. My goal is to develop hybrid nanocomposites, such as rGO/Ag₂MoO₄, with applications in photocatalysis, optical sensors, and electrochemistry. To characterize these materials, I use various techniques, including FTIR, XRD, XPS, PL, SEM, and EDS.
Applied Electrochemistry: Sensing and Electrocatalysis
Another major focus of my research is applied electrochemistry, with two main directions:
The development of electrochemical sensors for glucose detection, using nanostructured materials to enhance sensitivity and selectivity.
Electrocatalysis of pollutants, where I design modified electrodes to optimize electrochemical depollution in aqueous media.
Diffusion and Defects in Solids
I also study diffusion mechanisms in solids, particularly in polycrystalline and metallic systems. My research involves applying Fick’s laws and the Arrhenius relation to understand chemical species transport and the impact of point defects on material properties, particularly their optical and mechanical behavior.
Lasers and Optical Properties of Materials
Finally, I explore color centers in laser materials and their interaction with the crystal structure. I also analyze the effects of defects and doping on the optical properties of solids to optimize their performance for various applications.
