KNb3O8, K3N3Nb10,8O30, KNb3O8 niobate were obtained in the form of layered crystals of length 10-20 microns and a width of about 200-500 nm. They exhibite photocatalytic activity in the hydrogen evolution from aqueous solutions electron compounds (methanol, ethanol, iso-propanol, dimethylhydrazine) . The hierarchical mesoporous microsphere TiO2, formed a loose aggregation of crystals anataz about 10 nm, with higher activity in the photocatalytic hydrogen production from ethanol-water solutions and photoelectrochemical higher activity compared to nonporous preparation of nanocrystalline TiO2 P25. Photocatalytic heterostructures obtained by FTO / TiO2 / Sb2S3, photoelectrochemical are active in aqueous electrolytes containing sacrificial elektronodonor - ascorbic acid.
