Multigraph | Objectives

The main goal of MULTIGRAPH is to develop new eco-friendly graphene-multicomponent chalcogenide quantum dots composites applicable in different segments of the energy sector.

There are several objectives to accomplish the above mentioned goal (table below). Synthesis methods will be established for the preparation of untraditional multicomponent colloidal quantum dots (CQD) using non-toxic transition metals. In parallel, the graphene’s synthesis will be conducted via ultrasonic and electrochemical exfoliation. Another crucial aspect, from fundamental point of view, is the efficient approach of linking between the CQDs and graphene. Detailed investigations are required regarding the composites’ crystal and molecule structure, morphology, optical and electrochemical characteristics etc., which are of a great importance for the future innovative technological applications.

Different multicomponent chalcogenide systems is planned to be synthesized with a general formula M’M”QX, where M’ could be Cu, Mn, Mg, Ag (0 ≤ M’ ≤1); M” could be Ti, V, Zn, Ni (0 ≤ M” ≤ 1); Q could be Sn, Al (0 ≤ Q ≤ 1); X = S, Se, Te (1 ≤ X ≤ 4).

The graphene will be synthesized via electrochemical and direct ultrasonic liquid-phase exfoliation or combination of both.

Clarification of the role and mechanisms of the bifunctional linker molecules and electrochemically-assisted attachment to whole composite system behavior.
