High entropy metal chalcogenides: synthesis, properties, applications and future directions

Abstract

Metal oxides, sulphides, selenides and tellurides have routinely been investigated and utilised for a wide range of applications, in particular in the areas of energy (photovoltaic, thermoelectric) and catalysis (thermocatalysis,...

A facile synthetic route toward phase-pure colloidal Cu2GeS3 nanostructures mediated through metal xanthate precursors

“…Lewis's research group has extensively explored the versatility of metal xanthates and thiocarbamates for the phase-pure preparation of various exotic multinary metal sulfides. [14][15][16][17] Similarly, Revaprasadu et al have also investigated the suitability of xanthates and thiocarbamates for the preparation of several important nanosized metal sulfides. [18][19][20] However, a thorough literature study has revealed that xanthates have not been explored for the preparation of technologically important Cu 2 GeS 3 nanocrystals.…”

Facile synthesis and size-dependent optical properties of luminescent ZnIn2S4 nanocrystals derived from metal xanthates

“…One such method to synthesize phase pure multinary metal sulfides employing metal xanthates and thiocarbamates has been explored and established by Lewis [33][34][35] and Revaprasadu's group. [36][37][38] These metal xanthates being single source molecular precursors (SSMPs) have advantages over the normal metal salt precursors for the synthesis of ternary ZIS NCs.…”

Effect of Ag Content on the Electrochemical Performance of Ag2Te Nanostructures Synthesized by Hydrothermal Route for Supercapacitor Applications

“…35,36 The novel class of multifunctional materials known as transition metal telluride has gained a lot of interest recently owing its high electrical conductivity, varying valence states, and unique electrochemical characteristics, with comparison to the oxides, hydroxides, sulfides, and selenide despite the higher (electrical conductivity) Te ions in comparison with O/S/Se ions and it has weak metal-Te ionic bonds in host lattice structures. 37 However, (transition metal tellurides) generally struggled with large particle agglomeration and volume fluctuation throughout the prolonged cycling processes, leading to pulverization and morphological deterioration, fast capacity decline, and a shorter cycle life. However, the above concern problem has been improved by taking the appropriate concentration of the precursor in the synthesis of metal telluride leading to the change in morphology of the materials.…”
