Titanium Dioxide ТіО2

TiO2Materials Research Centre is actively involved in materials science and nanotechnology research. Namely, in the developing methods of synthesis of titanium dioxide (TiO2) nanopowders, and further investigation of its physical and chemical properties. MRC is researching the crystallinity, particle size, surface area, and other factors determine the functional characteristics and applications of the synthesized TiO2.

Materials Research Centre (MRC, Kiev, Ukraine) in cooperation with Drexel University, Philadelphia, USA designed and produced the first in Ukraine functional sample of dye-sensitized solar cell.

Batteries of this type have a simple structure, they consist of two electrodes, electrolyte and organic dye as a photosensitizer. One of the electrodes consists of a nanosized dye-saturated titanium dioxide (TiO2), deposited on a transparent conductive substrate. Other electrode is transparent substrate covered with a thin transparent layer of conductive material (ITO, Pt, etc.). Such batteries are promising alternative source of energy, since they don't require expensive materials and sophisticated equipment for their producing unlike to the silicon solar cells.
Prototypes of these solar cells created using nanomaterials by technologies developed in the laboratories of the Materials Research Centre and Drexel University from a raw materials of Ukrainian production. Now our researchers are working on improving the properties of materials used for completing solar cells for further increasing their efficiency.
Photoelectochemical systems on the base of nanocrystal wide bandgap oxide semiconductors sensitized by different types of dyes have the great potential to become an economically and commercially avaible for conversion and using of solar energy. Advantages of the photoelectochemical cells over conventional solar cells are following: 1) they don’t need ultra-pure substances; 2) they consist of low-cost materials and they are produced by processes that have little environmental impact; 3) they achieve reasonable efficiencies which are expected to improve by systematic research. There is a flexibility in the choice of material for each component, allowing the properties to be adjusted and optimised for practical applications.

ADVANCED SCIENCE NEWS: Yury Gogotsi was a chemist from the very beginning. He feels the excitement of scientific discovery, and cannot imagine doing anything else

Professor Yury Gogotsi, Drexel University, Philadelphia, USA

Yury Gogotsi was a chemist from the very beginning. He feels the excitement of scientific discovery, and cannot imagine doing anything else. It was love at first sight for Yury Gogotsi. 

Gogotsi feels that the greatest recent step in the field of materials science was the discovery of new 2D materials, the “building blocks of the future”. He is very enthusiastic about the use of nanotechnology to generate “new artificial materials, structures and devices from nanoscale building blocks” and the increased application of “modeling, simulation, and machine learning for solving materials science problems”, though he admits concern regarding the unknown effects that artificial intelligence will have on our future lives. He is also conscious of the energy required for computation and the importance of exploiting renewable resources to develop new technologies – ones that reduce energy consumption. “We need revolutionary discoveries here,” he says. “Evolutionary development won’t be enough.”
