Vacancy assisted growth of copper tantalum sulfide nanocrystals

Abstract

Cu-based ternary chalcogenides have received significant interest as an alternative to conventional photovoltaic materials. CuInS2 or CuInSe2 are the most studied copper-based ternary chalcogenides for photovoltaics. Recently, copper tantalum sulfide...

Solution-phase synthesis of group 3–5 transition metal chalcogenide inorganic nanomaterials

“…13(D)). 78 While the evidence suggests that the preparation of sulvanite nanoparticles via a direct route involves initial formation of copper chalcogenide precursors, the opposite order of formation has also been deliberately exploited by the Radu group in a ''cascade'' synthesis, where they prepared VSe 2 , NbE 2 , and TaE 2 (E = S, Se) nanosheets using methods discussed above, then injected CuCl 2 in oleylamine at elevated temperature, resulting in a transformation to sulvanite nanoparticles of varying morphologies (Fig. 13(E)-(H)).…”

Photoelectrochemical Engineering for Light‐Assisted Rechargeable Metal Batteries: Mechanism, Development, and Future

“…[51][52][53] In addition, metalfriendly surfaces with appropriate surface energy/diffusion barriers and efficient photocatalytic effects need to be selected by crystal plane optimization to promote uniform deposition of Li and inhibit dendrite formation. [54][55][56] Taking zinc oxide (ZnO) as an example, the (002) crystal plane with a high-efficiency photo effect has a relatively few electron-hole pair recombination rate. By generating a weak electron layer on the surface to enhance the adsorption of Li + , the energy barrier of Li deposition was reduced and the electrochemical kinetics of light-assisted Li anodes were improved effectively (Figure 3d).…”
