“…When the temperature exceeds 366°C, Ni‐Fe LDH completely decomposes into metal oxides with good thermal stability, whereas the molecular chain of QAPPT continues to degrade. Therefore, with an increase in LDH content, the weight loss of the composite membrane decreases and its thermal stability increases 58 …”

Summary The development of alkaline membranes with high conductivity and stability is a significant challenge for the commercial application of advanced alkaline water electrolysis. In this study, a novel anion exchange membrane (AEM) was fabricated by quaternary ammonium poly (n‐methyl‐piperidine‐co‐p‐terphenyl) (QAPPT) and Ni‐Fe layered double hydroxide (LDH) synthesis for advanced alkaline water electrolysis. The uniform dispersion of Ni‐Fe LDH in the QAPPT/Ni‐Fe LDH composite membrane was confirmed by scanning electron microscopy, showing that Ni‐Fe LDH provides the composite membrane with high OH− conductivity and tensile strength. Among different membrane samples, the QAPPT/3% Ni‐Fe LDH composite membrane exhibited the best conductivity with 217.6 mS cm−1 at 80°C. Furthermore, the QAPPT/3% Ni‐Fe LDH composite membrane showed outstanding electrolysis performance of 1 A cm−2 at the voltage of 1.824 V at 60°C. According to a long‐term stability test, conducted at 500 mA cm−2 for more than 87 h, the QAPPT/3% Ni‐Fe LDH composite membrane achieved satisfactory electrolysis voltage. This study's results show that QAPPT/Ni‐Fe LDH composite membranes have excellent application prospects in advanced alkaline water electrolysis.

“…A broad range between 3000 and 3750 cm −1 is observed, characterized by the prolonged OH group of hydroxide layer and water blending between 1600 and 1650 cm −1 (O–H blending) present on all of the samples. 7,42 LDH-Cl exhibited a well-defined peak at a frequency of 1368 cm −1 , which can be attributed to the presence of Cl − anions in the LDH structure. 39 The weak absorption bands located at 2926 cm −1 and 1120 cm −1 may correspond to the C–O and C–H stretching of the lactate anion present in LDH-Cl.…”

“…The strong absorption peak at 1371 cm −1 is associated with the vibration mode of the carbonate group, while the peaks at 553 and 678 cm −1 are related to metal−oxygen stretching vibration in the octahedral layers of LDH. 36,37 In the case of coated particles, a significant absorption band was observed in the range 1300−700 cm −1 , pointing to the presence of silica. The LDH@SiO 2 absorption bands appeared at 1087 cm −1 in response to the Si−O−Si stretched vibrating, 38,39 confirming the successful coating of LDH nanoparticles with SiO 2 .…”

The innovative hollow silica nanoparticle (HSN) material possesses substantial potential for application in the insulation field. The size and shell thickness of HSN are crucial factors in determining their inherent properties, which, in turn, impact their applicability. This research presents a facile approach to synthesizing HSN in which sodium silicate (Na 2 SiO 3 ) was utilized as the silica precursor that can be directly deposited onto layered double hydroxide (LDH) nanoparticles without the utilization of any surfactant. A subsequent acid treatment was used to eliminate the templates, resulting in the formation of an HSN devoid of mesopores in silica shells. By utilizing various sizes of LDH cores, obtainable via coprecipitation followed by hydrothermal treatment, we were capable of successfully synthesizing the hollow particles with adjustable diameters ranging from 50 to 200 nm. In addition, the shell thickness is varied from 6.8 to 22.5 nm by varying the silicate solution concentration. Results demonstrate that prepared HSNs have low thermal conductivity and high reflectance in the UV−vis−NIR range (averaging 82.1%). These findings suggest that HSN can be utilized as an effective inorganic filler in the formulation of reflective and thermally insulating coatings.
