“…Meanwhile, the localized states induced by carbon doping would act as a springboard for the migration of VB generated electron to the CB, thus promoting charge carriers separation and migration [ 50 ]. Moreover, the electrons excited from the VB of CBO to the CB could be collected by CQDs, thus extending the lifetime of electrons [ 67 ]. Subsequently, holes remaining in the VB or in localized states or both would be directly involved in the oxidation of ceftriaxone sodium.…”

Although there is significant progress in the research of carbon dots (CDs), some challenges such as difficulty in large-scale synthesis, complicated purification, low quantum yield, ambiguity in structure-property correlation, electronic structures, and photophysics are still major obstacles that hinder the commercial use of CDs. Recent advances in synthesis, modification, characterization, and applications of CDs are summarized in this review. We illustrate some examples to correlate process parameters, structures, compositions, properties, and performances of CDs-based materials. The advances in the synthesis approach, purification methods, and modification/doping methods for the synthesis of CDs are also presented. Moreover, some examples of the kilogram-scale fabrication of CDs are given. The properties and performance of CDs can be tuned by some synthesis parameters, such as the incubation time and precursor ratio, the laser pulse width, and the average molar mass of the polymeric precursor. Surface passivation also has a significant influence on the particle sizes of CDs. Moreover, some factors affect the properties and performance of CDs, such as the polarity-sensitive fluorescence effect and concentration-dependent multicolor luminescence, together with the size and surface states of CDs. The synchrotron near-edge X-ray absorption fine structure (NEXAFS) test has been proved to be a useful tool to explore the correlation among structural features, photophysics, and emission performance of CDs. Recent advances of CDs in bioimaging, sensing, therapy, energy, fertilizer, separation, security authentication, food packing, flame retardant, and co-catalyst for environmental remediation applications were reviewed in this article. Furthermore, the roles of CDs, doped CDs, and their composites in these applications were also demonstrated.

“…This phenomenon may be ascribed to the high content of CQDs around the composite. 55 The excessive loading of N,S-CQDs hinders the light-harvesting and charge-transfer capabilities of the pure ZnO nanoparticle surfaces, thereby reducing the photocatalytic performance. 56 The photo-catalytic reaction kinetics corresponds to the Langmuir-Hinshelwood kinetic model and follows the pseudo first-order reaction process.…”
