Duration of the project: 01.01. 2018 – 31.12.2020
Project executor: Vasyl Stefanyk Precarpathian National University (Ministry of Education and Science of Ukraine)
Project goals: the development of reproducible synthesis methods of nanocomposites based on the quasi-two-dimensional MoS2 or WS2 and carbon with controlled structural, morphological, optical and electrochemical characteristics optimized for its effective application in the spheres of energy storage and tribology.
- Testing and improvment of the obtaining methods of the Q2D TMD /carbon hierarchical nanostructures with onion- and sandwich-like morphologies, using hydrothermal synthesis;
- Obtain materials which combine advantages of few-layer transition metal dichalcogenides and carbon nanoparticles (with graphene–like ordering or close to amorphous mesoporous);
- Find general regularity between structural, morphological and electro-physical properties control for Q2D MoS2 or WS2 and carbon (graphene oxide or reduced graphene oxide) composites obtained by hydrothermal route;
- To find optimal combination of structural, morphological and electro-physical properties of Q2D MoS2 (or WS2) / carbon hierarchical ordered nanocomposites which allow its effective using as electrode for supercapacitors;
- To study the tribological properties of multilayered hydrothermally synthesized MoS2 (or WS2) / carbon hierarchical ordered nanocomposite with onion-like or lamellar morphology as an additive to base oil and as a solid lubricant.
- The hydrothermal synthesis development of nanocomposites quasi-two-dimensional (Q2D) MoS2 or WS2 / carbon (amourphous carbon, graphene oxide or reduced graphene oxide) with predicted structural, morphological, optical and electrochemical characteristics obtaining; special attend will be paid to multilayered hierarchical structure formation and investigation;
- Testing of obtained Q2D TMD / carbon nanocomposites as an electrode material for hybrid supercapacitors; experimental finding of optimal combination of material morphology (spherical, lamellar, sponge-like) and electrical conductivity for certain electrolyte to reach maximal specific capacity and best cycling characteristics of model supercapacitors.
