Nanotechnology preparation of a MIS photoelectrode with metallic oxides for systems for production of solar fuels
Nanotechnológia prípravy MIS fotoelektród s oxidmi kovov pre systémy na výrobu solárnych palív
Program: SRDA
Project leader: Ing. Fröhlich Karol DrSc.
Annotation:Effective energy generation from renewable sources plays ever more important role in terms of sustainable energetic self-sufficiency and ecology. The project is therefore focused on fabrication and analysis of highly stable and efficient metal-insulator-semiconductor (MIS) structures with dielectric protective layers for photoelectrochemical (PEC) water splitting. Such structures form a key element of stable systems, which provide the conversion of sun light energy into the chemical energy of so-called solar fuels with high energy density, e.g. hydrogen. This method of long time sun energy utilization is unlike the photovoltaic structures feasible without the need of battery usage, which makes it a highly perspective concept of renewable and sustainable energy source. Through a multidisciplinary research in the field of fabrication and optimization of layers, interfaces and processes in MIS structures with protective dielectric and conductive catalytic layers, the project aims to achieve optimal values of photo-voltage, photo-current and stability of photoanode properties for the efficient generation of solar fuels. The project is focused also on the explanation of the charge carriers transport mechanisms in the MIS structure, which will allow achieving a high photo-voltage. We will compare TiO2 and HfO2 oxides prepared by atomic layer deposition (ALD) as the protective layers as well as the NiO, RuO2 and RuO2-IrO2 oxides prepared by magnetron sputtering and MOCVD in the role of conductive transparent catalytic layers. The experimental technological processes will be supported by simulations.

Tribological properties of 2D materials and related nanocomposites
Tribologické vlastnosti 2D materiálov a príbuzných nanokompozitov
Program: SRDA
Project leader: Ing. Ťapajna Milan PhD.
Annotation:Tribological effects have been estimated to generate about 23% of the world’s total energy consumption. Lowfriction coating is the most widely applied technology to improve the tribological behaviour, acting as solid lubricants. Many solid lubricating coatings including TiN, TiC, diamond-like C, and graphite are nowadays usedby the industry. Compering to these traditional coatings, 2-dimensional (2D) materials offer some exceptional advantages, such as extremely low friction, wetting transparency, and oxidation resistance. However, deposition of 2D materials in larger scale by industry-friendly equipment is not yet available. Moreover, there has been only limited progress in detail understanding of the mechanical behaviour of 2D materials. Therefore, this project aims to develop existing technologies for deposition of 2D materials and nanocomposites for low friction coating, targeting primarily micrometre (MEMS) as well as centimetre scale (micro-machinery and medical components) applications. We will employ three different techniques for large-scale deposition of emerging (graphene, MoS2, WS2) and new 2D materials (transition metal diselenides) and nanocomposites. We will also focus on development of dedicated adhesion-improving interlayers such as B4C and graphene oxide. Nanotribological studies using friction force microscopy and nanowear analysis will be performed, aiming deeper understanding of the 2D material-substrate interactions. The prepared 2D materials will be also characterized using set of suitable analytical methods in order to gain knowledge on structure-properties relation. The most promising technologies developed at nanoscale will be then transferred to micro- and eventually macroscale and tested. Finally, we will attempt to develop tailored low-friction coatings for selected applications.
