Broadening the range of light absorption and inhibiting charge carrier's recombination are vital to improving photocatalytic activity. In this study, a novel full spectrum light-driven carbon quantum dots (CQDs) modified 2D-2D ZnInS/BiOCl van der Waals (VDW) heterostructures were prepared by a facile hydrothermal method. It exhibits remarkable degradation efficiency for removing various antibiotics from water (i.e. tetracycline (TC), ciprofloxacin (CIP) and oxytetracycline (OTC) under visible and near-infrared (NIR) light. The enhancement of photocatalytic performance is due to the 2D-2D VDW heterostructures and CQDs not only accelerate the interfacial charge separation and transfer but also provide massive reactive canters to facilitate degradation reaction. Besides, the optical absorption capacity of CQDs modified 2D-2D ZnInS/BiOCl VDW heterostructures are obviously enhanced because of the up-conversion photoluminescence (UC-PL) properties of CQDs. Furthermore, the degradation process of TC is assessed by three-dimensional excitation-emission matrix (3D-EEMs) and liquid chromatography-tandem mass (LC-MS/MS) spectrometry analysis. Active species trapping experiments and electron spin resonance (ESR) testify that O, OH, and holes play a crucial part in the photocatalytic degradation process. This work affords a new promising approach for CQDs modified 2D/2D VDW heterojunction with enhanced photoactivity in organic pollutant degradation for full spectrum light utilization.

Food derived from genetically modified organisms (ORGANISMS, GENETICALLY MODIFIED).
Clonal hematopoetic disorder caused by an acquired genetic defect in PLURIPOTENT STEM CELLS. It starts in MYELOID CELLS of the bone marrow, invades the blood and then other organs. The condition progresses from a stable, more indolent, chronic phase (LEUKEMIA, MYELOID, CHRONIC PHASE) lasting up to 7 years, to an advanced phase composed of an accelerated phase (LEUKEMIA, MYELOID, ACCELERATED PHASE) and BLAST CRISIS.
Changes in the organism associated with senescence, occurring at an accelerated rate.
A modified nucleoside which is present in the first position of the anticodon of tRNA-tyrosine, tRNA-histidine, tRNA-asparagine and tRNA-aspartic acid of many organisms. It is believed to play a role in the regulatory function of tRNA. Nucleoside Q can be further modified to nucleoside Q*, which has a mannose or galactose moiety linked to position 4 of its cyclopentenediol moiety.
Antibodies from non-human species whose protein sequences have been modified to make them nearly identical with human antibodies. If the constant region and part of the variable region are replaced, they are called humanized. If only the constant region is modified they are called chimeric. INN names for humanized antibodies end in -zumab.
