Synthesis and assembly of monodisperse spherical Cu2S nanocrystals

Highly stable and regenerable Mn-based/SBA-15 sorbents for desulfurization of hot coal gas

“…5A(a)), which is characteristic of Cu 2+ in CuO [49]. Over used sample, the main peak of Cu 2p 3 shifts toward lower BEs (932.3 eV), exhibiting the characteristic XPS spectrum of Cu + in Cu 2 S [50]. In addition, two bread-type peaks at 161.8 and 168 eV can be attributed to the signals of S 2p 3/2 in sulfides and sulfates, respectively (magnification curves in Fig.…”

From Cu2S nanocrystals to Cu doped CdS nanocrystals through cation exchange: controlled synthesis, optical properties and their p-type conductivity research

“…The copper stearate (Cu(St) 2 ) was systhesized according to the reference [30]. Then, 0.25 mmol (157.7 mg) Cu(St) 2 and 0.25 mL DDT were mixed in a Teflon autoclave, followed by adding 5 mL oleic acid and 3 mL oleymanine.…”

Colloidal Copper Sulphide Based Nanocrystals as Building Blocks for Self-assembled Nanostructures

“…Also the position of the localized surface plasmon resonance band, which is located in the near-IR region for copper sulphide particles, depends on the aggregation of the particles and could be switched between 1850 and 1600 nm by the generation of the supperlattice or its dissolution [62]. Another example of the importance of ligands in the formation of ordered superlattice structures was demonstrated by Li et al [68], who studied self-assembly of quasi-spherical dodecanethiol stabilized copper sulphide nanocrystals. When the amount of this stabilizer was increased, three-dimensional superlattices were formed instead of two-dimensional ones (Fig.…”
