In the modern world, the economic growth is mainly provided by the development of energy technologies. Modern energy is commonly based on the use of traditional fossil fuels, which are considered limited, non-renewable and not environmentally friendly. One of the ways to overcome the energy and environmental crisis is the implementation of non-traditional catalytic technologies using available renewable fuel and raw materials such as solar energy and biomass. Progress in this area is largely due to the development of high-throughput and economically viable technologies for creating catalytically active materials. The scientific novelty of the project lies in solving the problem of developing a high-performance controlled electrochemical synthesis of active materials for photoinduced processes of purification of water resources from toxic pollutants and generation of hydrogen from aqueous solutions of biomass components and products of its processing. Equipment and technological solutions will be developed to control the process of electrochemical synthesis of dispersed oxy(hydroxy)des of a number of metals (V, Bi, W, Ti, Fe, etc.). Regularities will be revealed that relate the electrical, physical and chemical parameters of synthesis, the rate of formation, composition, structural, morphological and optical characteristics of dispersed oxy(hydroxy)des of metals, their activity and stability in photoinduced processes of water purification from organic compounds and hydrogen generation from biomass aqueous solutions. As a result of the project, new principles will be developed for controlling the activity of dispersed oxy(hydroxy)des of metals in photoinduced reactions, which will make a significant contribution to increasing the competitiveness of renewable energy sources and reducing the carbon intensity of manufactured goods and energy, and will also serve as scientific and technological foundations for creating low-waste, low-tonnage technologies for creating demanded materials for modern environmentally friendly and resource-saving energy.
