This review analyses the role of viologens, a unique class of redox-active molecules in various energy storage devices and the nature of chemical interactions in enhancing their overall performances.
Synthesis of Cu 2 ZnSnS 4 nanoparticles by solution based solid state reaction process and its application in dye sensitized solar cell as counter electrode AIP Conf.Abstract. Copper tungstate (CuWO 4 ) nanoparticles were prepared by Solid state synthesis. The CuWO 4 nanoparticles were synthesized by reacting 1:1 mole ratio of copper chloride and sodium tungstate. The XRD pattern reveals that the synthesized CuWO 4 has anorthic (triclinic) structure. In addition, the average grain size, lattice parameter values were also calculated using XRD data. The FT-IR analysis confirm the presence of Cu-O and W-O bonds in CuWO 4 nanoparticles. The electrochemical sensing behavior of CuWO 4 nanoparticles towards 4-chlorophenol was investigated using cyclic voltammetry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
