dcterms:description
The synthesis of various inorganic compounds using ionizing radiation (IR) or UV light represents a very promising technological field. Radiation-induced processes have some advantages over common chemical methods: they are mostly independent of temperature, and they yield material of high purity, with narrow size distribution of particles. Radiation technique is a rather simple method for preparation of various compounds. It is based on irradiation of aqueous solutions containing suitable precursors with ionizing or UV radiation. Finely dispersed solid phase formed during irradiation is subsequently separated from solution, dried, and either used as is, or further processed by calcination at high temperatures under various atmospheres. The preparation enables fast production of practical amounts of powder materials, usually with narrow particle size distribution and high chemical and phase purity. Moreover, no strict control of experimental conditions is required. The method has been successfully tested for preparation of a variety of nanoscale compounds, namely, metals, metal alloys, and core–shell systems, metal oxides, garnets, various heterostructures, and nanocomposites. Materials consisting of nanometer-sized particles have drawn substantial attention in a wide range of research fields, mostly for their various unique properties originating from their small size or related high specific surface area. For this reason, the nanoscale materials are considered for many applications (e.g., as phosphors, catalysts, or sorbents). This chapter summarizes methods for radiation preparation of various metal oxides and reviews their selected prospective applications.
