“…Rare-earth-based metal-organic frameworks (MOFs) are actively used in various fields of science and technology as luminescent sensors [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ], LED components [ 12 ], luminescent probes for bioimaging [ 13 , 14 ], and luminescent thermometers [ 15 , 16 ]. Small-sized crystals of the rare-earth-based MOFs are especially interesting due to their unique properties.…”

“…MOFs are actively used as luminescent and electrochemical sensors for heavy metal ion detection in drinking and wastewater [ 1 , 2 , 3 , 6 , 7 , 10 ]. Nanosized luminescent MOFs are able to penetrate the cell membrane and are therefore used in bioimaging as luminescent probes [ 13 , 14 ]. The nano-sized rare-earth-based MOFs can be synthesized by several synthetic routes [ 13 , 14 , 22 , 23 , 24 , 25 ] such as solvothermal, reverse microemulsion, surfactant-assisted, microwave, and ultrasonic methods.…”

The luminescent coarse-, micro- and nanocrystalline europium(III) terephthalate tetrahydrate (Eu2bdc3‧4H2O) metal-organic frameworks were synthesized by the ultrasound-assisted wet-chemical method. Electron micrographs show that the europium(III) terephthalate microparticles are 7 μm long leaf-like plates. According to the dynamic light scattering technique, the average size of the Eu2bdc3‧4H2O nanoparticles is equal to about 8 ± 2 nm. Thereby, the reported Eu2bdc3‧4H2O nanoparticles are the smallest nanosized rare-earth-based MOF crystals, to the best of our knowledge. The synthesized materials demonstrate red emission due to the 5D0–7FJ transitions of Eu3+ upon 250 nm excitation into 1ππ* state of the terephthalate ion. Size reduction results in broadened emission bands, an increase in the non-radiative rate constants and a decrease in both the quantum efficiency of the 5D0 level and Eu3+ and the luminescence quantum yields. Cu2+, Cr3+, and Fe3+ ions efficiently and selectively quench the luminescence of nanocrystalline europium(III) terephthalate, which makes it a prospective material for luminescent probes to monitor these ions in waste and drinking water.

Photocatalysis is considered to be a green and environment‐friendly technology since it can convert solar energy into other types of chemical energies. Over the past several years, metal‐organic frameworks (MOFs)‐based photocatalysts have received remarkable research interest due to their unique morphology, high photocatalytic performance, good chemical stability, easy synthesis, and low cost. In this review, the synthetic strategies of developing MOFs‐based photocatalysts are first introduced. Second, the recent progress in the fabrication of various types of MOFs composites photocatalysts is summarized. Third, the different applications including hydrogen evolution reaction, oxygen evolution reaction, overall water splitting, nitrogen reduction reaction, carbon dioxide reduction reaction as well as photodegradation of organic pollutants of MOFs‐based photocatalysts are summed up. Finally, the challenges and some suggestions for the future development of MOFs‐ and their composites‐based photocatalysts are also highlighted. It is expected that this report will help researchers to systematically devise and develop highly efficient photocatalysts based on MOFs and their composites.

“…MOFs are 3D nanomaterials that have attracted great attention due to their unique characteristics, such as regular and interconnected porosity, ultrahigh specific surface area, and intraframework chemical functionality [220]. However, the electrically insulating nature of most MOFs might hamper their practical use in electrochemical and electronic applications.…”

View full text Add to dashboard Cite

Graphene quantum dots (GQDs) have been widely investigated in recent years due to their outstanding physicochemical properties. Their remarkable characteristics allied to their capability of being easily synthesized and combined with other materials have allowed their use as electrochemical sensing platforms. In this work, we survey recent applications of GQDs-based nanocomposites in electrochemical sensors and biosensors. Firstly, the main characteristics and synthesis methods of GQDs are addressed. Next, the strategies generally used to obtain the GQDs nanocomposites are discussed. Emphasis is given on the applications of GQDs combined with distinct 0D, 1D, 2D nanomaterials, metal-organic frameworks (MOFs), molecularly imprinted polymers (MIPs), ionic liquids, as well as other types of materials, in varied electrochemical sensors and biosensors for detecting analytes of environmental, medical, and agricultural interest. We also discuss the current trends and challenges towards real applications of GQDs in electrochemical sensors.
