Abstract
EN In recent years, the dynamic development of civilization and technological progress has contributed to the growing problem of increased pollution as well as energy shortage. Therefore, one of the challenges that scientists focus on is to develop of a new, effective technology to solve the mentioned problems. Among commonly proposed technologies, semiconductor-based photocatalysis has great application potential. Different materials are used as photocatalysts, and still, the aim is to obtain new systems that will be biologically inert, photostable, chemically resistant, relatively cheap, and most importantly, will becharacterized by high photooxidative activity and spectral response. Among the well-known and widely available materials, semiconductors are the most popular. However, those materials exhibit some limitations that can be overcame by selecting an appropriate method of their synthesis or modification. The key aspect is to select proper components which together with specific semiconductors, will build materials, exhibiting enhanced photocatalytic or photovoltaic activity. Among many solutions proposed, the formation of heterostructured systems, can be mentioned. An essential aspect in the synthesis of these materials seems to be skillful and conscious control of changes related to determining the impact of the synthesis method, type, and quantity of components used on their physicochemical and functional properties. The presented research concern the applicationof hydro/solvothermal and microwave methods for fabrication of heterostructured materials with strictly defined morphology and structural properties. Moreover, considering specificproperties of lanthanides, such as unique magnetic, optical, and redox properties, it is expected that their incorporation into the structure of semiconductors during synthesis stage will translate into increased photocatalytic and photovoltaic activity.
