“…This may be because the amino group was protonated in an acidic environment. 42 The emission intensity could be significantly enhanced by the addition of F − (Figure 3c). Contrary, the influence of other anions (Cl − , Br − , I − NO 3 − , CO 3 2− , SO 4 2− , and PO 4 3− ) or cations (Cu 2+ , Hg 2+ , Co 2+ , and Zn 2+ ) on the emission intensity was not significant.…”

Excessive fluorine can cause a serious threat to human health. It is significant but challenging to develop a straightforward and rapid way to simultaneously detect and remove excess F − from water. Herein, we presented a three-dimensional (3D) hierarchical UiO-66-NH 2 nanoparticle/γ-AlO(OH) nanowire hybrid synthesized by a facile biotemplate route for simultaneous detection and removal of F − from water. We elaborately assembled two kinds of materials in a bioinspired 3D hierarchical structure as a functional unit to achieve detection and removal of dual functions. The outer UiO-66-NH 2 nanoparticles served as a fluorescent sensor to detect and capture F − via a strong fluorescence enhancement effect caused by the electron transfer from F − and γ-AlO(OH) and acted as the capture unit of F − . The inner γ-AlO(OH) nanowire layer served as a F − absorbent through ion exchange between F − and γ-AlO(OH). The resulting UiO-66-NH 2 nanoparticle/γ-AlO(OH) nanowire hybrid displayed excellent selectivity and sensitivity for F − detection (the detection range was 0−5 mM and the limit of detection was as low as 0.77 μM) and high capacity for F − removal (the maximum equilibrium adsorption capacity q max was as high as 87.0 mg g −1 ). This dualfunction material provided a strategy for simultaneously selective sensing and efficient removal of anionic pollutants from water.

“…The above-mentioned results indicated that Cu-MOFs can become potential fluorescent materials. 51,52 Detection of glyphosate Glyphosate (GLYP), as a pollutant, has posed a serious threat to public health. In order to evaluate the selectivity of the system, the fluorescence quenching efficiency of pesticide products, namely, nicosulfuron methyl (NSF), fluorophenylurea (TFB), chlorsulfuron methyl (CHL), carbaryl (CA), cyanofoxate (CB), atrazine (AZ), thiamethoxam (TMT), methyl Paraben (M 4 H), and carbendazim (CBD), and the selectivity were studied according to the fluorescence spectral intensity (Fig.…”

The development of carbon dots (CDs), either using green or chemical precursors, has inevitably led to their wide range application, from bioimaging to optoelectronic devices. The reported precursors and properties of these CDs have opened new opportunities for the future development of high-quality CDs and applications. Green precursors were classified into fruits, vegetables, flowers, leaves, seeds, stem, crop residues, fungi/bacteria species, and waste products, while the chemical precursors were classified into acid reagents and non-acid reagents. This paper quickly reviews ten years of the synthesis of CDs using green and chemical precursors. The application of CDs as sensing materials in optical sensor techniques for environmental monitoring, including the detection of heavy metal ions, phenol, pesticides, and nitroaromatic explosives, was also discussed in this review. This profound review will offer knowledge for the upcoming community of researchers interested in synthesizing high-quality CDs for various applications.
