| Summary: | <span>In the present work formation of active TiO<sub>2</sub> nanoparticles in microwave synthesis and their modification with platinum were studied. Anatase nanopowder and 10 M KOH solution were used as raw materials. Microwave assisted synthesis method permited to obtain TiO<sub>2</sub> nanofibres and nanowires with a diameter of 10 nm and a specific surface area in the range of 70<sub> </sub>–<sub> </sub>150 m<sup>2</sup>/g. In order to modify TiO<sub>2 </sub>nanofibers with platinum it was stirred in H<sub>2</sub>PtCl<sub>6</sub> solution under UV irradiation. Photocatalytic activity was </span><span>determined by degradation <span>of the methylene blue (MB) solution under UV and visible light irradiation. The obtained samples showed higher photocatalytic activity with respect to pure TiO<sub>2</sub> nanofibers. The doped TiO<sub>2</sub> nanofibers were appropriate for degradation of harmful organic compounds as well as for hydrogen production by water splitting.</span></span> |
