Ternary Chalcogenide-Based Quantum Dots and Carbon Nanotubes: Establishing a Toolbox for Controlled Formation of Nanocomposites

Abstract: A general procedure based on electrostatic self-assembly for preparing nanocomposites based on carbon nanotubes (CNTs) and ternary chalcogenide semiconductor nanoparticles is shown. This was achieved by surface functionalization of the single components through well-established protocols, for CNTs, and a transferable general strategy for the nanoparticles. Heterostructures were then synthesized through electrostatic interaction between oppositely charged components. Structural, colloidal, and optical propertie… Show more

“…The charge accumulation, in addition to the charge carrier (donor) densities (N d ) can further be calculated from the slope of the 1/C 2 versus potential plot (Equation 1). Tri-hybrid has a charge carrier density of 5.8×10 19 cm À 3, which is higher compared to 4.32×10 19 cm À 3 for the PbS-TiO 2 junction. The increment of donor densities of the tri-hybrid photoanode is in cobordance with our explanation of…”

“…Otherwise, a long insulating ligand covering the surface of QD would restrict the interfacial interaction between QD and the substrate [18] . However, these methods involve lengthy synthesis procedures and can reduce QD stability [19] . Therefore, adsorbing QDs on the surface of TiO 2 ‐CNT nanohybrid can serve the two‐in‐one purpose, which colocalizes the QD with CNT on the surface of TiO 2 and would resolve the problem of rigorous ligand exchange to get better attachment affinity with CNT.…”
