Mechanism for strong binding of CdSe quantum dots to multiwall carbon nanotubes for solar energy harvesting.
As hybrid nanomaterials have myriad of applications in modern technology, different functionalization strategies are being intensely sought for preparing nanocomposites with tunable properties and structures. Multi-Walled Carbon Nanotube (MWNT)/CdSe Quantum Dot (QD) heterostructures serve as an important example for an active component of solar cells. The attachment mechanism of CdSe QDs and MW...
متن کاملPreparation, characterization and the use of sulfonic acid-functionalized phthalimide (SFP) as a highly efficient and green catalyst for the condensation of arylaldehydes with 2-naphthol
Phthalimide was reacted with chlorosulfonic acid to give sulfonic acid-functionalized phthalimide (SFP), which characterized by 1H NMR, 13C NMR, FT-IR, XRD (X-ray diffraction), SEM (scanning electron microscopy), EDX (energy-dispersive X-ray), mass, TG (thermogravimetry) and DTG (derivative thermal gravimetry) spectra. Afterward, its catalytic activity was examined for the condensation of aryla...

متن کاملSynthesis and Characterization of Functionalized SBA-15 Mesoporous Silica by N, N´-Bis(salicylidene)ethylenediamine Schiff-Base
In this work, BSEA-SBA-15 was prepared for the first time, which was prepared by covalently anchoring Schiff-base compound (N,N´-bis(salicylidene)ethylenediamine (BSEA) on SBA-15 by hydrothermal method. The structure and physicochemical properties were determined by elemental analysis, XRD, nitrogen adsorption–desorption, thermogravimetric analysis and FTIR spectroscopy, SEM, BET surface area a...
متن کاملPolyurea-functionalized multiwalled carbon nanotubes: synthesis, morphology, and Raman spectroscopy.
An in situ polycondensation approach was applied to functionalize multiwalled carbon nanotubes (MWNTs), resulting in various linear or hyperbranched polycondensed polymers [e.g., polyureas, polyurethanes, and poly(urea-urethane)-bonded carbon nanotubes]. The quantity of the grafted polymer can be easily controlled by the feed ratio of monomers. As a typical example, the polyurea-functionalized ...
