Various forms of SnSe and composite of Bi2Se3 with Polypyrrole synthesis characterization and material evaluation for various applications

Abstract

Researchers have recently been interested in low-dimensional nanostructures for nonconventional energy generation and cleaning up the environment. The renewable energy sources are receiving greater attention than ever before as a result of global climate change and the depletion of fossil fuel stocks. newlineAmong the chalcogenides, SnSe has gained significant research interest due to its versatility in various fields like thermoelectricity, gas sensing, anode for battery, super capacitor, memory switching devices, topological insulator, photocatalytic, piezoelectric and optoelectronic device and the properties varied depending on process of synthesis. SnSe can be synthesized by various chemical and physical methods like solvothermal, hydrothermal, electrodeposition, chemical-bath deposition, spray pyrolysis, thermal evaporation, etc., either in the form of powder or thin films respectively. newlineThe first study covers the methylene blue (MB) and malachite green (MG) dye degradation utilizing electrochemically synthesized tin selenide (SnSe) thin films as photocatalysts in the presence of visible light. newlineThe second work is based on a comparison of the performance of photoelectrochemical (PEC) cells made of SnSe films made using electrodeposition and solvothermal processes, respectively. newlineThe third work is the thermoelectric characteristics of tin selenide (SnSe) thin film, which was produced electrochemically on an FTO substrate at 27 °C with a deposition potential of - newline0.6 V (Ag/AgCl reference electrode). newline newlineImproved thermoelectric characteristics of hydrothermally synthesized P-type co-doped SnSe with varying copper (Cu) and silver (Ag) doping percentages have been reported in the fourth work. newlineA comparison of the thermoelectric performance of hybrid materials, polypyrrole/bismuth selenide (PPy/Bi2Se3) and polypyrrole/Nickel doped bismuth selenide (PPy/Ni doped Bi2Se3) produced by in situ polymerization and solvothermal synthesis, has been demonstrated. in the fifth study. newlineImproved thermoelectric characteristics of hydrothermal
