The present article reports the hydrothermal synthesis of quaternary Cu2MnSnS4 (CMTS) nanostructures underrnsubcritical reaction conditions. The effect of different chalcogen (sulfur) precursor sources (L-cysteine, elementalrnsulfur and sodium sulfide) on the growth and properties of the nanostructures is studied. The sulfur precursorsrnshowed prominent influence on the structural and morphological properties of the nanostructures. Structuralrnproperties indicated the growth of single phase crystalline materials. The crystal phase was controlled andrndetermined by the reactivity of the sulfur sources. Metastable wurtzite phase was achieved with the mildlyrnreactive precursor while tetragonal phase was obtained in the case of highly reactive precursors. Morphologicalrnstudies showed formation of nanoflakes and anisotropic two-dimensional irregular nanostructures. Surface arearnanalysis indicated that the nanoflakes are mesoporous in nature and exhibited a high specific surface area ofrn32.24 m2/g. The electrical studies demonstrated p-type conductivity of the material. Optical properties revealedrnoptimum energy band gap value (~1.7 eV) of the nanostructures, suitable for the solar energy conversion aprnplications. The magnetic properties indicated ferromagnetic behavior of the CMTS nanoflakes. The nanornstructures were investigated as catalysts for photocatalytic decolaration of malachite green (MG) dye underrnUV–Visible light illumination. The nanoflakes showed good activity against the dye and photodegraded 95% ofrnthe dye in an illumination duration of 140 min. The photocatalysts exhibited good stability during the photorncatalytic processes.
