Title : Nano-Materials, synthesis, characterization and applications
Recently Nano-materials were applied in different fields as chemistry, medicine and agriculture.. The present lecture categorized to three Items. The first discuss some of the methods used to synthesize the materials in the nano forms, the second category explained the tools used to characterize the synthized nano-materials and The third part presents some applications. the present work concentrated on the applications of Nano-materials in chemistry
The nanomaterial's were synthesized using different method viz chemical, mechanical and biological methods. The nano-structure materials were characterized using electron-microscopy and other tools . The prepared materials used to modify carbon paste electrode. modified electrode were widely used for the electrochemical determination of pollutants, metal ions and pharmaceutical compounds.
From other hand the prepared materials were used to remove pollutants.Through photocatalytic decomposition A detection limit of about 10-10 M was obtained using electrochemical techniques such as linear sweep voltammetry, differential pulse voltammetry and square wave voltammetry. Modification of the carbon paste electrodes increased the surface area and enhance the sensitivity comparing to non-modified electrode. Another application of nanomaterial's is the removal of some pollutants. A removal of about 80 % from some pollutants was achieved using TiO2 nano particles.
The lecture allows the participants to know about the different methods used to synthesize nano-materials. Also the audience will take the opportunity to discuss how and why the nano-materials characterized?. At the end of lectures many applications are presented and what are the expected applications in the different fields of chemistry.
