“…Some works have indicated that in situ growth of MOF on LDH can be applied in electrochemistry. [31,32] Zhang et al prepared HKUST@CoNiLDH as an electrode material for supercapacitors by electrodeposition. [33] In this work, NiCo-LDH multilayered nanosheets were prepared by a simple hydrothermal method, and a series of NiCo-LDH@M-HHTP(-EtOH) (M = Ni or Co) composites were synthesized by regulating the solvent.…”

Metal‐organic frameworks (MOFs) have been widely concerned as functional materials with excellent properties. However, most MOFs are of poor electrical conductivity, which hinders their further application in electrochemical fields. Fortunately, the emergence of intrinsically conductive MOFs (c‐MOFs) alleviates this problem. Layered double hydroxides (LDHs) possess Faraday redox reactivity, which is favorable to capacitors. In this paper, we combined c‐MOFs with LDHs and prepared a series of NiCo‐LDH@M‐HHTP(‐EtOH) (M = Ni or Co; HHTP = 2,3,6,7,10,11‐hexahydroxytriphenylene) multilayer nanoarrays, and the effects of solvent on the morphology and energy storage properties of the materials were investigated. When NiCo‐LDH@Co‐HHTP‐EtOH is applied as an electrode material in supercapacitors, it exhibits a capacitance of 830 F g‐1 at 1 A g‐1. What’s more, it exhibits high energy density and excellent rate performance when assembled in aqueous asymmetric supercapacitors.

“…For example, the MOF nanomaterials, which are enriched with p-electron-rich ligands, possess the ability to adsorb single-stranded DNA (ssDNA) by means of p–p stacking interactions. This interaction leads to the quenching of labeled fluorophores, which is an increasingly popular application for MOFs. , The second point is the strong complexation of the Zr–O–P bonds. Zirconium (Zr)-based MOFs, such as UiO-66, UiO-67, 509-MOF, and so on, possess the superiority for developing sensitive biosensors because of the strong interaction between the zirconium node and phosphate groups of biomolecules .…”

Tunable detection of microRNA is crucial to meet the desired demand for sample species with varying concentrations in clinical settings. Herein, we present a DNA walker-based molecular circuit for the detection of miRNA-21 (miR-21) with tunable dynamic ranges and sensitivity levels ranging from fM to pM. The phosphate-activated fluorescence of UiO-66-NH2 metal–organic framework nanoparticles was used as label-free fluorescence tags due to their competitive coordination effect with the Zr atom, which significantly inhibited the ligand-to-metal charge transfer. To achieve a tunable detection performance for miR-21, the ultraviolet sensitive o-nitrobenzyl was induced as a photocleavable linker, which was inserted at various sites between the loop and the stem of the hairpin probe to regulate the DNA strand displacement reaction. The dynamic range can be precisely regulated from 700- to 67,000-fold with tunable limits of detection ranging from 2.5 fM to 36.7 pM. Impressively, a Boolean logic tree and complex molecular circuit were constructed for logic computation and cancer diagnosis in clinical blood samples. This intelligent biosensing method presents a powerful solution for converting complex biosensing systems into actionable healthcare decisions and will facilitate early disease diagnosis.

“…The presence of iron vacancies increases electron mobility, which optimizes the hydrogen adsorption free energy to effectively increase the catalytic activity of FeP . Moreover, the porous structure can expose abundant active sites, improve atomic utilization, favor electrolyte penetration and accelerate ion/mass transport, and then significantly facilitate the HER reaction process. , Conventional phosphorization methods typically involve high-temperature thermal treatments, which is often accompanied by a recrystallization process that may lead to a reduction in defects in the sample, thus limiting the electrochemical properties of the material to some extent . Therefore, developing a simple and rapid synthesis approach of TMPs at room temperature is imperative.…”

Investigating high-efficiency electrocatalysts toward hydrogen evolution reaction under wide pH conditions is a pivotal task for large-scale hydrogen generation. Herein, a straightforward reduction method is developed for the synthesis of amorphous Ru coupled with defect-abundant B-doped FeP4/Fe2P porous nanospheres (Ru/B-p-FeP4/Fe2P) at an ambient environment. The porous structure and abundant defects expose rich active sites and favor mass and electron transfer in the electrochemical reaction process. In addition, the introduced Ru also favors boosting the reaction kinetics. Thus, the designed Ru/B-p-FeP4/Fe2P catalyst possesses low overpotentials of 44, 55, 92, and 72 mV to drive 10 mA cm–2 in acidic, alkaline, neutral, and alkaline seawater electrolytes. This work provides a rapid approach to synthesizing pH universal metal phosphide catalysts at room temperature.
