Synthesis of carbon quantum dot-surface modified P25 nanocomposites for photocatalytic degradation of p-nitrophenol and acid violet 43

Abstract

A new efficient and stable visible light driven photocatalyst, carbon quantum dots (CQDs)-surface modified P25 nanocomposite, was successfully prepared by chemical adsorption of CQDs onto the surface of TiO2 nanoparticles and then used for water treatment.

H:ZnO Nanorod-Based Photoanode Sensitized by CdS and Carbon Quantum Dots for Photoelectrochemical Water Splitting

“…24 In addition, the role of carbon-based quantum dots was investigated thoroughly for the improvement of photo-degradation under a solar light source as illustrated source through UCPL characteristics. 8,25 To the best of our knowledge, the deposition of CdS and CQDs on hydrogenated ZnO nanorods for the improvement of hydrogen generation efficiency has not yet been reported.…”

Large-scale synthesis of carbon dots/TiO2 nanocomposites for the photocatalytic color switching system

“…2A indicates the existence of Ti (2p), C (1s), N (1s), O (1s) in the composites. The Ti 2p spectrum has two peaks at 458.4 eV and 464.2 eV, corresponding to the Ti 2p 1/2 and Ti 2p 3/2 of P25, respectively, while there is slight blue shi towards a higher binding energy compared with those in the spectrum of pure P25 (458.7 eV and 464.6 eV), 32 indicating that the CDs could scavenge photo-generated holes and reduce the electron-hole recombination. The highresolution C 1s spectrum in Fig.…”

Facile thermochemical conversion of FeOOH nanorods to ZnFe2O4nanorods for high-rate lithium storage

“…On the other hand, the amounts of carbon in C/ZFO-NR was very small ($0.1%) according to the TGA result, it indicates that most are ZFO-NR in C/ZFO-NR sample and the carbon is present in small amounts on the surface of ZFO-NR. 23 The morphologies of the prepared samples were characterized using SEM. As shown in Fig.…”
