Synthesis methods for chalcogenides and chalcogenides-based nanomaterials for photocatalysis

Abstract In this chapter, the synthesis strategies of chalcogenide-based nanomaterials in order to obtain desired properties for photocatalytic application are reviewed. The different dimensional structures of nanomaterials as well as the number of involved elements, from binary to multinary compound system of chalcogenide offer complexities in designing suitable fabrication method. Scientists have developed a variety of methods for the preparation of nanostructured chalcogenide compound, including the solvothermal and hydrothermal, hot/noninjection method, solid synthesis method, thermal decomposition, template-directed synthesis among others. These methods can be classified as direct and indirect synthesis methods. Stoichiometry tuning and structure modification in relation to desired photocatalytic properties are highly dependent on the preparation strategies. The novel cutting-edge technology and future development of chalcogenide nanomaterials synthesis technique are also discussed.
