Project Title: Deterministic plasma approach for synthesis of high performance light harvesting hybrid assembly
The main aim of this proposal is to use appropriate plasma diagnostics to deduce the plasma chemistry in RF Plasmas processing of commercial carbon cloths to develop controlled and deterministic plasma based synthesis of highly porous nanostructurized (nitrogen/sulphur) doped carbon cloths (nDCC) which will be used as electrode for transition metal –nitrides and/or -dichalcogenides to prepare cost effect hybrid light harvesting assemblies of TMNs//TMDs@nDCC for enhanced photo-catalytic performance.
The three-dimensional (3D) hierarchical nano-architecture of nDCC will be achieved via one-step nitrogen/sulfur RF plasma processing. Different parameters including flow rate, background pressure of nitrogen gas/sulfur vapor, RF plasma power and discharge duration will be optimized using optical emission spectroscopy together the characteristics of nDCC obtained. This will contribute to developing a controllable and deterministic plasma approach for nDCC fabrication with desired physical and chemical characteristics.
The synthesis of hierarchical porous hybrid light harvesting assemblies will be followed by loading transitional metal nitrides (TMNs), and/or transitional metal dichalcogenides (TMDs) on the surface of nDCC through various plasma-assisted approaches and/or chemical methods. Finally the optimization of structural, morphological, electrical and optical properties of hybrid assemblies will be done to achieve highest possible photo-catalytic performance.
The project will develop a reactive plasma chemistry based synthesis of TMNs//TMDs@nDCC using cost effect commercial carbon cloth with an aim to do away with traditional method of trial and error by developing controllable and deterministic plasma approach using plasma diagnostics as tool.
