“…it is suggested that the exposed metal‐semiconductor interfaces in dimers perform better than buried interfaces in core‐shell nanomaterials . Other quaternary chalcogenides such as anisotropic kesterite CZTSe, orthorhombic CZGeS, NCs and CFTS microspheres have also displayed strong visible region photon absorption and enable high photocatalytic RhB degradation efficiency under visible‐light illumination ,,. Further, we have also observed the photocatalytic reduction of toxic and mutagenic Cr(VI) species to non‐toxic Cr(III) in presence of hydrophilic CZTS NPs under illumination, The photocatalytic application of CZTS is further evident for multifunctional application of these quaternary chalcogenides.…”

“…In our previous report, we have also reported the synthesis of anisotropic CZTSe nanoparticles using one pot colloidal synthetic technique . The flower like morphology obtained because of different ratio of bulky, straight chain ligands, and long reaction time, which resulted in the attachment of smaller CZTSe nanocrystals into random orientation and gave rise to 3D flower like morphology a shown in Figure .…”

“…Here also the CZTX materials are not left behind. We recently explored and reported the excellent photocatalytic dye degradation efficiency of the CZTS and CZTSe ,. The instantaneous degradation of carcinogenic dyes such as rhodamine B (RhB), methylene blue (MB), methyl red and EY with as‐observed high rate constant and excellent cyclability show the efficient reaction kinetics.…”

Cu-based quaternary chalcogenide semiconductors have been attractive materials in many aspects since the last decade. Most of the scientific literature about quaternary chalcogenides is dedicated to photovoltaic (PV) research with no astonishment as the material initially emerged as a costeffective replacement of expensive Si for PV applications. These materials possess all the important properties such as, abundant and non-toxic constituent elements, efficient charge transport, optimum band gap, and high absorption coefficient for being an efficient PV material in either thin film or nanoparticle form. However, in the recent few years, a new range of quaternary materials Cu 2 M I M II X 4 (where, M I =Zn, Ni, Co, Fe, Mn, Cd and Hg; M II =Si, Sn and Ge and X=S and/or Se) have evolved and found applications in thermoelectrics, photocatalysis and photoelectrocatalysis, sensors and bat-teries etc. The combination of properties exhibited by these quaternary chalcogenides such as optical and electric, optical and magnetic, electric and thermal makes them potential materials, which could be utilized in multiple applications. Although the PV properties of these quaternary chalcogenides has been discussed earlier in many reports, the other versatile applications of the material have not been reviewed yet. The present article sheds light on the multifunctional aspects of various new Cu-based quaternary chalcogenides, their synthesis, effect of doping on their properties, and then elaborating the discussion on their chemical and physical properties that are helpful in different applications along with photovoltaics. Here, we discuss synthetic methods bestowing enhanced features and also summarize their achieved efficiency in recent years. Scheme 1.

“…[22] Kush et al reported 0.004 mM of methylene blue (MB) and RhB solutions which were degraded under indoor illumination above 90% within 35 and 120 min, respectively. [23] To the best of our knowledge, there are very limited results available on CZTSe-based photocatalytic studies for the degradation of MB dye which is the motivation for this research. So, the present research work highlights the synthesis of CZTSe NPs through hotinjection method using oleic acid as solvent.…”

Cu2ZnSnSe4 (CZTSe) nanoparticles (NPs) are successfully synthesized via cost‐effective hot‐injection process and morphologically modified by biphasic ligand exchange method. X‐ray diffraction (XRD) results indicate kesterite phase for the as‐prepared CZTSe NPs. Scherrer equation is used to evaluate the average crystallite size (≈30 nm). Scanning electron microscopy (SEM) images reveal that the interconnected nanoflakes structure combines to produce hierarchical CZTSe nanoflower. Fourier‐transform infrared spectroscopy (FTIR) results confirm the replacement of native long‐chain ligand over the surface of NPs with inorganic salts. The optical studies reveal that the CZTSe NPs have a large absorbance over the visible region with optimum bandgap value of 1.23 eV. The photocatalytic studies confirm the high efficiency of CZTSe NPs in degrading the methylene blue (MB) dye within 120 min under visible light irradiation. The intermediate products formed during the degradation of MB have been analyzed by electrospray ionization mass spectrometry (ESI‐MS). The photocatalytic degradation mechanism is discussed.

“…The shape of anisotropic particles are determined by competing factors, such as preferential attachment to different crystal facets, surfactant-mediated directional growth, and surface coordinating ligands 11 – 13 . There have been a number of interesting anisotropic nanostructures prepared using this technique including nanorods 14 – 16 , wires 17 , 18 , tetrapods 19 – 21 , multipods 22 , dumbbells 23 and platelets 24 , 25 , among others. However, most of the methods reported to date, describe only the synthesis of one material and have specific cocktails of many various reagents.…”

The hot injection synthesis of nanomaterials is a highly diverse and fundamental field of chemical research, which has shown much success in the bottom up approach to nanomaterial design. Here we report a synthetic strategy for the production of anisotropic metal chalcogenide nanomaterials of different compositions and shapes, using an optimised hot injection approach. Its unique advantage compared to other hot injection routes is that it employs one chemical to act as many agents: high boiling point, viscous solvent, reducing agent, and surface coordinating ligand. It has been employed to produce a range of nanomaterials, such as CuS, Bi2S3, Cu2-xSe, FeSe2, and Bi4Se3, among others, with various structures including nanoplates and nanosheets. Overall, this article will highlight the excellent versatility of the method, which can be tuned to produce many different materials and shapes. In addition, due to the nature of the synthesis, 2D nanomaterial products are produced as monolayers without the need for exfoliation; a significant achievement towards future development of these materials.
