“…D ligands, composed of a thiol group at the end of the chain, served as additional passivation ligands after T stabilized the QDs in the liquid and solid phases. 33 CDNA could be used as an efficient template for QDs in solid films due to its unique polymeric nature (rigidity, transparency, and biocompatibility).…”

“…Different routes have been used in synthesizing nanocrystalline ZnO powders as well as other nanostructures such as hydrothermal, spray pyrolysis, sol-gel, precipitation, microwave assisted, thermos-decomposition processes, micro-emulsion, electrodeposition, ultrasonic, microwave-assisted technique and chemical vapour deposition [19][20][21][22][23][24][25][26][27]. All these methods produce similar nanocrystalline structures based on different conditions.…”

Single phase ZnO nanostructures were synthesized by simple and low temperature solvothermal process from two different alkaline sources; Potassium hydroxide (KOH) and Sodium hydroxide (NaOH) with zinc acetate dihydrate (Zn(CH3COO)2∙2H2O) as precursor. This facile and rapid synthesis technique achieve high purity of Zinc oxide (ZnO) nanostructures on large scale negating the use of complex and high temperature routes. The synthesized particles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), Transmission Electron Microscopy (TEM), Energy-dispersive X-ray spectroscopy (EDX), Fourier Transform Infrared (FT-IR) Spectroscopy, Ultraviolet Visible (UV-Vis) spectroscopy and Brunauer-Emmett-Teller (BET) analysis. ZnO synthesized using KOH and NaOH exhibit wurtzite hexagonal and flake-like nanostructures with average crystallite size of 11.0 nm and 14.9 nm respectively. Surface area of 59.50 m2/g and 31.43 m2/g were determined for KOH and NaOH sources respectively. The optical absorption spectra of the two samples showed absorption bands of 367.70 and 365.30 nm. The results showed the effect of alkaline sources on the surface morphology, structural and optical properties of ZnO.

“…However, the main challenge lies in the development of convenient and reliable synthetic methodologies that could allow for precise tuning of their composition and crystal structure. Many scientists have relied heavily on solution-phase synthetic approaches (e.g., hydrothermal/solvothermal technique, colloidal chemical method) because of their potential to control not only the composition and crystal phase but also the size and morphology of materials. ,− The materials that are synthesized in solution are typically nanoscale structures (i.e., nanostructures) with size- and morphology-dependent properties that are not observed in the bulk solids. Therefore, nanoscale engineering through controlled synthesis in solution provides additional options for property tuning that can be exploited in the rational design of functional CMS-based materials toward desired applications.…”

Copper-based multinary sulfides (CMSs) have been the subject of intense research over the past decade due to the numerous outstanding properties that emerge when they are synthesized on the nanoscale. CMS compounds (e.g., CuInS 2 , Cu 2 SnS 3 , Cu 12 Sb 4 S 13 , and Cu 2 ZnSnS 4 ) are best known for their immense potential in energy-related disciplines. Through nanoscale engineering, new and exciting opportunities have opened up for these materials to be used in a wider range of applications. This review accords particular attention to nanostructured CMS materials with porous morphological features to be used in energy, biomedical, catalytic, and sensing applications owing to their large, tunable, and accessible surface area. Although the construction of porous nanostructures of metals and binary materials has already been well established, tailoring porosity in multinary materials like CMSs remains a big challenge due to their multiple elemental components. Herein, we provide useful discussions on the different modes of pore formation that are fundamental to the construction of CMS nanostructures with tailor-made porosity. These pore-forming strategies are classified into three types: (1) Kirkendall effectinduced hollowing, (2) aggregation-based pore formation, and (3) template-assisted pore engineering. The ability to craft porous features in CMS nanomaterials has proven to be beneficial in advancing their properties and expanding their application domains, and thus, future efforts should be devoted to furthering our understanding of the various pore formation mechanisms as this could lead to the construction of more sophisticated porous CMS architectures with optimal performance for desired applications. We anticipate that the design concepts discussed here can be extended to other emerging classes of multinary materials.
