Due to advancements in technology, the energy demand is becoming more intense with time. The rapid fossil fuels consumption and environmental concerns triggered intensive research for alternative renewable energy resources, including sunlight and wind. Yet, due to their time‐dependent operations, significant electric energy storage systems are required to store substantial energy. In this regard, electrochemical energy storage devices, like batteries and supercapacitors (SCs), have recently attracted much research attention. Recent developments in SCs demonstrated that hybrid SCs (HSCs), which combine the excellent properties of batteries and SCs, increase the specific energy, specific power, specific capacitance, and life span. Carbonaceous and redox‐active materials have been explored as efficient electrode materials for applications in HSCs, ultimately enhancing their electrochemical performances. The HSCs performance significantly depends on the porosity, specific surface area, and conductivity of the electrode materials. This review article gives an overview of recent advances in developing HSCs with high specific power, specific energy, and long cyclic‐life. The fabrication of various HSCs materials using carbonaceous and redox‐active nanoarchitectures and their characterization are explored in‐depth, including electrode development, basic principles, and device engineering. A proper investigation has been conducted regarding state‐of‐the‐art materials as HSC electrodes. This review focuses on the most up‐to‐date, cutting‐edge, electrode materials for HSCs and their performance. The possibilities for novel electrode materials and their impact on the HSCs performance for future energy storage are also discussed.

“…In addition, in acidic media, the removal capacity of LDHs is compromised due to low structural stability at low pH [ 26 ]. In Table 2 , we collected characteristics of methods of synthesis which can be followed for the preparation of pure LDHs, as well as their composites and hybrids [ 18 , 25 , 41 , 42 ].…”

Within the frame of this article, briefly but comprehensively, we present the existing knowledge, perspectives, and challenges for the utilization of Layered Double Hydroxides (LDHs) as adsorbents against a plethora of pollutants in aquatic matrixes. The use of LDHs as adsorbents was established by considering their significant physicochemical features, including their textural, structural, morphological, and chemical composition, as well as their method of synthesis, followed by their advantages and disadvantages as remediation media. The utilization of LDHs towards the adsorptive removal of dyes, metals, oxyanions, and emerging pollutants is critically reviewed, while all the reported kinds of interactions that gather the removal are collectively presented. Finally, future perspectives on the topic are discussed. It is expected that this discussion will encourage researchers in the area to seek new ideas for the design, development, and applications of novel LDHs-based nanomaterials as selective adsorbents, and hence to further explore the potential of their utilization also for analytic approaches to detect and monitor various pollutants.

“…On the basis of the remarkable PEC performance of NiCo-LDHs/TiO 2 NTAs and the excellent adsorption performance of the LDHs for Cr(VI), 63 it is highly desirable to develop a PEC sensor with high electroreduction and sensing ability for Cr(VI) detection. In this work, a NiCo-LDHs-modified TiO 2 NTAs/Ti photoelectrode with a controllable loading amount of NiCo-LDHs was fabricated by using anodization and electrodeposition procedures.…”

Developing stable and highly efficient photoactive materials is desirable to their extensive application in photoelectrochemical (PEC) sensors. Herein, a nickel−cobalt layered double hydroxides (NiCo-LDHs) cocatalyst-modified TiO 2 nanotube arrays (TiO 2 NTAs) photoelectrode (NiCo-LDHs/TiO 2 NTAs/ Ti) was fabricated and used to construct a PEC sensing platform for hexavalent chromium, Cr(VI), detection. The resultant NiCo-LDHs/TiO 2 NTAs/Ti showed higher photocatalytic water-splitting activity than the pristine TiO 2 NTAs/Ti, and an enhanced anodic photocurrent was realized at a potential of 0 V (vs Ag/AgCl). On the basis of changes of the photocurrent signal induced by the interaction between photogenerated electrons and Cr(VI) as an effective electron scavenger in solution, a PEC sensor for Cr(VI) detection was developed and showed a linearly decreased photocurrent with increasing Cr(VI) concentration between 0.5−20 μM, 20−400 μM, and 400−1800 μM with a 0.12 μM detection limit under the optimized test conditions. The method showed simplicity, excellent selectivity and sensitivity, a wide linearity range, and high stability. The prepared PEC sensor succeeded in the Cr(VI) detection of river water and tap water samples, and it presented good applicability.
