“…Li et al heat-treated NiFe-LDHs synthesized via urea hydrolysis under hydrothermal conditions for 2 days, resulting in large nanosheet growths around 500 nm. They synthesized an 8-hydroxypyrene-1,3,6trisulfonicacid trisodium (HPTS)/NiFe-LDH hybrid material for fluorescent CO 2 detection via a one-pot hydrothermal process [87]. Ni(NO 3 ) 2 •6H 2 O, Fe(NO 3 ) 3 •9H 2 O, urea, and trisodium citrate were added to an HPTS solution under a nitrogen atmosphere.…”

Layered double hydroxides (LDHs) have attracted considerable attention as promising materials for electrochemical and optical sensors owing to their excellent catalytic properties, facile synthesis strategies, highly tunable morphology, and versatile hosting ability. LDH-based electrochemical sensors are affordable alternatives to traditional precious-metal-based sensors, as LDHs can be synthesized from abundant inorganic precursors. LDH-modified probes can directly catalyze or host catalytic compounds that facilitate analyte redox reactions, detected as changes in the probe’s current, voltage, or resistance. The porous and lamellar structure of LDHs allows rapid analyte diffusion and abundant active sites for enhanced sensor sensitivity. LDHs can be composed of conductive materials such as reduced graphene oxide (rGO) or metal nanoparticles for improved catalytic activity and analyte selectivity. As optical sensors, LDHs provide a spacious, stable structure for synergistic guest–host interactions. LDHs can immobilize fluorophores, chemiluminescence reactants, and other spectroscopically active materials to reduce the aggregation and dissolution of the embedded sensor molecules, yielding enhanced optical responses and increased probe reusability. This review discusses standard LDH synthesis methods and overviews the different electrochemical and optical analysis techniques. Furthermore, the designs and modifications of exemplary LDHs and LDH composite materials are analyzed, focusing on the analytical performance of LDH-based sensors for key biomarkers and pollutants, including glucose, dopamine (DA), H2O2, metal ions, nitrogen-based toxins, and other organic compounds.

“…A strong broad band around 3400 cm -1 corresponds to the stretching mode of metal-OH and hydrogen bonded H 2 O surrounding the interlayer anion. The absorption peak at 1640 cm -1 could be ascribed to the H-O-H bending vibration of interlayer water molecules, while those at 1360 and 750 cm -1 could be assigned to the asymmetric stretching vibration of CO 3 2 13,[18][19] . The FT-IR spectra of CoFe LDH do not contain signals associated with the interlayer carbonate anion (1360 cm -1 ).…”

For electric energy storage device electrodes with nanosheet architectures can offer the possibility to achieve enhanced energy storage performance. Layered double hydroxide (LDH) is one of the candidate of electrode materials for electrochemical capacitor. Herein, we have successfully synthesized CoAl, NiAl and NiFe LDH nano-films grown on Ni substrate by hydrothermal methods. For CoFe, LDH nano-film cannot be obtained using same experiment conditions. SEM micrographs show that the thickness of LDH layered nanosheet are ~100, ~ 40 and ~85 nm for CoAl, NiAl and NiFe samples. The LDHs nanosheet film were grown perpendicularly on the substrate as electrode materials. The electrochemical performance of LDHs were tested by cyclic voltammetry. The measured cyclic voltammograms indicated that CoAl LDH has the best reversibility and the highest capacitance (554 F/g) among the three types of LDHs. A good cycling stability was also observed for the CoAl LDH nanosheet with the specific capacitance remained at 425 F/g and retained 77.3% of the high value after 6000 cycles at current density 10A/g.

“…In recent years, the use of LDHs as sensors is increasing. In some cases, they can be used as fluorescence chemosensors [24][25][26]. In the others, electrochemical sensing applications of LDHs have expanded [27][28][29][30][31][32][33][34].…”

In recent years, the unique properties of Layered Double Hydroxides (LDHs) led to an interest in using LDHs as sensors, but gas sensing properties of LDHs have not still been broadly investigated. In this work, Ni-Cr-Al LDH was synthesized by co-precipitation method and was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Fourier-transform infrared spectroscopy (FTIR), and then, its sensing properties were investigated in the presence of various gases at room temperature (25 ± 2 °C). It was observed that the sensors resistance changes in the presence of acetone were descending, and the opposite trend was observed for alcohols. The sensor's selectivity and stability were acceptable, but its response and recovery times were somewhat long (about a few minutes).
