The project aims at the development of phisical and chemical principles of new efficient photocatalytic systems based on nanocrystalline semiconductors and nanocomposites for the production of molecular hydrogen.
An analysis of the modern state of the topical problem of hydrogen production in the semiconductor-based photocatalytic and photoelectrocatalytic systems was performed. It was demonstrated that the problem of hydrogen production from aqueous solutions of electron donating substrates as well as stoichiometric water cleavage using semiconductor photocatalysts develops mainly in the direction of the design of visible-light-sensitive photocatalysis both on molecular and nanoscale levels.
A number of efficient photocatalytic systems for hydrogen production from aqueous solutions of electron donating substrates (alcohols, amines, carbon acid, carbohydrates, sodium sulfide and sulfite, etc.) was developed using the CdxZn1-xS/Ni nanoheterostructures in the form of both colloidal solutions and nanocrystalline powders, as well as the photocatalytically-produced mesoporous TiO2/metal nanocomposites.
