| Abstract Scope |
It is frequently thought that ionizing radiation, such as alpha, beta, gamma, X-rays causes deleterious effects on materials. Although true under some circumstances, ionizing radiation is also a powerful tool for materials processing in areas such as controlled synthesis of nanostructures, materials’ surface, and nanostructure proprieties modification, among others. For example, it has been evidenced that radiation chemistry for materials’ synthesis can be performed at ambient conditions (no thermal input required), it eliminates the need for reducing agents, and it does not generate toxic byproducts.
This talk highlights the use of ionizing radiation as a synthesis and processing tool of inorganic nanomaterials for applications in medicine and catalysis. Initially, the synthesis of metal nanoparticles supported on various materials such as ceramic nanoparticles and 3D supports will be discussed. A synergism between nanoparticles and support often leads to enhanced properties. Finally, X-ray irradiation as a novel surface treatment to improve the photocatalysis performance of TiO2 will be described in light of the materials’ surface chemistry. |
