Preparation of Ag3PO4tetrapods anchored to nitrogen-doped carbon quantum dots for enhanced photocatalytic performance

“…3(e), the C–C and CC show the two strong peaks at 285.0 eV and 292.5 eV, which are the typical peaks of carbon materials, assigned to their nonpolar σ bonds and π bonds. 34–36 Another two flat peaks at 286.9 eV (C–N) and 288.5 eV (C–O), ascribe to the polar σ and π bonds in NCQDs, respectively. 37,38 In Fig.…”

Nitrogen‐Doped Carbon Quantum Dots on Graphene for Field‐Effect Transistor Optoelectronic Memories

“…To this aim, colloidal carbon quantum dots (CQDs), [31][32][33] highly luminescent nanoparticles of carbon which is one of the most abundant elements in our planet, could be excellent candidates. They can be readily synthesized in water by various biosourced materials such as citric acid, [34] orange peels, [35] water hyacinth leaves, [36] and pomegranate [37] under relatively mild synthesis temperature (≤200 °C) by hydrothermal, solvothermal, or microwave routes, giving nanoparticles with dimensions ranging from a few to a few tens of nanometers. Instead of being controlled by the nanoparticle dimension, their optical properties are controlled by their rich surface chemical groups and dopants which can be tuned from the synthetic routes and the choice of reactants.…”

Revolutionizing fuel production through biologically synthesized zero-dimensional nanoparticles

“…Additionally, CQDs exhibit up-down photoluminescence (PL) conversion and the ability to accept and donate electrons. 34–36 Some studies have employed CQDs as one of their composite materials to prepare CQDs/CuS, 37 Fe 2 O 3 /CQDs, 38 CQDs/CuO, 5 CQDs/ZnO, 39 CQD/TiO 2 , 40,41 CQDs/Sb 2 WO 6 (ref. 42) and CQD/PCN (polymeric carbon nitride).…”
