“…MOFs and their hybrid materials have been also employed as interesting platforms to photovoltaic devices [70] and organic light-emitting devices (OLEDS) [71] thanks to some special properties of the MOF materials with excellent performance and stability. The worldwide need of energy is rapidly increasing day after day, but it should be up against the severe pollution issues of the environment along with decreasing resources in the meantime.…”

The high speed of contaminants growth needs the burgeoning of new analytical techniques to keep up with the continuous demand for monitoring and legislation on food safety and environmental pollution control. Metal-organic frameworks (MOFs) are a kind of advanced crystal porous materials with controllable apertures, which are self-assembled by organic ligands and inorganic metal nodes. They have the merits of large specific surface areas, high porosity and the diversity of structures and functions. Latterly, the utilization of metal-organic frameworks has attracted much attention in environmental protection and the food industry. MOFs have exhibited great value as sensing materials for many targets. Among many sensing methods, fluorometric sensing is one of the widely studied methods in the detection of harmful substances in food and environmental samples. Fluorometric detection based on MOFs and its functional materials is currently one of the most key research subjects in the food and environmental fields. It has gradually become a hot research direction to construct the highly sensitive rapid sensors to detect harmful substances in the food matrix based on metal-organic frameworks. In this paper, we introduced the synthesis and detection application characteristics (absorption, fluorescence, etc.) of metal-organic frameworks. We summarized their applications in the MOFs-based fluorometric detection of harmful substances in food and water over the past few years. The harmful substances mainly include heavy metals, organic pollutants and other small molecules, etc. On this basis, the future development and possible application of the MOFs have prospected in this review paper.

“…This also can enrich the PC performance. In addition, we examined the CD performance for Car-CTF-5-500 over the range of À 1.0 to 0.0 V, using currents of 10,11,12,14,15,16,17,18,19 and 20 μA/cm 2 [ Figure 6(g)]. The CD curves reveal typical symmetrical CD patterns with a negligible internal resistance drop, indicating that the hybridization did not induce further resistive structure.…”

“…To ensure excellent reversibility and rapid transfer of electrolyte ions at the interface between the electrolyte and the electrode, the electrode materials should possess a hierarchical porous structure and a large electrolyte surface area . Accordingly, several advanced porous materials prepared with heteroatom doping, high surface areas, controllable pore size distributions, and excellent electrochemical stability, including covalent triazine‐based frameworks (CTFs), conjugated microporous polymers (CMPs), and metal organic frameworks (MOFs), are promising candidates for use as electrode materials in energy storage devices . CTFs are a subclass of covalent organic frameworks (COFs); they are high‐performance microporous polymeric materials .…”

In this study a series of bicarbazole‐based covalent triazine frameworks (Car‐CTFs) were synthesized under ionothermal conditions from [9,9'‐bicarbazole]‐3,3',6,6'‐tetracarbonitrile (Car‐4CN) in the presence of molten zinc chloride. Thermogravimetric and Brunauer−Emmett−Teller analyses revealed that these Car‐CTFs possessed excellent thermal stabilities and high specific surface areas (ca. 1400 m2/g). The electrochemical performances of this Car‐CTF series, investigated by using cyclic voltammetry, showed a highest capacitance of (545 F/g at 5 mV/s), which also exhibited excellent columbic efficiencies of 96.1 % after 8000 cycles at 100 μA/0.5 cm2. The other Car‐CTF samples displayed similar efficiencies. Furthermore, based on CO2 uptake measurements, one of the series showed the highest CO2 uptake capacities: 3.91 and 7.60 mmol/g at 298 and 273 K, respectively. These results suggest a simple method for the preparation of CTF materials that provide excellent electrochemical and CO2 uptake performance.

“…Inspired by natural principles, for decades there has been a continuous effort to design artificial photosynthetic assemblies based on the use of solar energy to generate oxygen and hydrogen by water splitting [ 4 , 5 , 6 ]. Over the years, multiple candidates such as titanium dioxide (TiO 2 ), zinc oxide (ZnO), tungsten trioxide (WO 3 ), cadmium sulfide (CdS), among others [ 7 , 8 , 9 , 10 , 11 ] have been used to produce hydrogen via water splitting [ 12 , 13 ]. From all these photocatalysts, TiO 2 has been extensively studied over the years mainly due to its chemical stability, abundance, non-toxicity, and high hydrogen yield [ 12 ].…”

“…Similar to titanium oxide, ZnO has also been demonstrated to be chemically stable, easy to produce, non-toxic, abundant, and environmentally-friendly [ 9 , 10 ], although unlike titanium dioxide, ZnO has been widely used for the degradation of organic pollutants and energy storage [ 14 , 15 , 16 ]. Some authors [ 17 , 18 ] consider that ZnO shows some disadvantages for the production of hydrogen by water splitting, especially the recombination of photogenerated electron–hole pairs, fast backward reaction, and the inability to use visible light.…”

For some decades, the scientific community has been looking for alternatives to the use of fossil fuels that allow for the planet’s sustainable and environmentally-friendly development. To do this, attempts have been made to mimic some processes that occur in nature, among which the photosystem-II stands out, which allows water splitting operating with different steps to generate oxygen and hydrogen. This research presents promising results using synthetic catalysts, which try to simulate some natural processes, and which are based on Au@ZnO–graphene compounds. These catalysts were prepared by incorporating different amounts of gold nanoparticles (1 wt.%, 3 wt.%, 5 wt.%, 10 wt.%) and graphene (1 wt.%) on the surface of synthesized zinc oxide nanowires (ZnO NWs), and zinc oxide nanoparticles (ZnO NPs), along with a commercial form (commercial ZnO) for comparison purposes. The highest amount of hydrogen (1127 μmol/hg) was reported by ZnO NWs with a gold and graphene loadings of 10 wt.% and 1 wt.%, respectively, under irradiation at 400 nm. Quantities of 759 μmol/hg and 709 μmol/hg were obtained with catalysts based on ZnO NPs and commercial ZnO, respectively. The photocatalytic activity of all composites increased with respect to the bare semiconductors, being 2.5 times higher in ZnO NWs, 8.8 times higher for ZnO NPs, and 7.5 times higher for commercial ZnO. The high photocatalytic activity of the catalysts is attributed, mainly, to the synergism between the different amount of gold and graphene incorporated, and the surface area of the composites.
