The project aims to develop science-based principles for the creation of materials and technologies that will allow the use of sunlight as a cost-effective energy source and close the existing gap between theoretically available and practically usable solar energy. The solution to this problem will be achieved through the development of new scalable approaches to the synthesis of powder hybrid photocatalysts based on tungsten oxides WOx/MeOx (Me=Zn, Fe) with high photocatalytic activity and stability under sunlight. During the implementation of the project, the influence of technological modes of electrochemical synthesis and heat treatment modes on the rate of formation, composition, structural and optical characteristics of photocatalysts will be evaluated. New data will be obtained on the optimal parameters of degradation of antibiotics and pesticides in the presence of synthesized materials under the action of sunlight in a specially designed flow type photocatalyst installation and technological recommendations will be given for the synthesis and use of hybrid powder materials based on tungsten oxide in photocatalysis, which is of high practical importance for the development and will be an important step towards the practical application of photocatalytic technologies in general. A comprehensive study of the fundamental and applied properties of synthesized materials will open the way to obtaining hybrid photocatalysts with a high efficiency of solar light utilization in wastewater treatment processes, including agriculture, from pesticides and antibiotics.
