The determination of ammonium ions (NH4 +) is of significance to environmental, agriculture, and human health. Potentiometric NH4 + sensors based on solid-contact ion selective electrodes (SC-ISEs) feature point-of-care testing and miniaturization. However, the state-of-the-art SC-ISEs of NH4 + during the past 20 years strongly rely on the organic ammonium ionophore-based ion selective membrane (ISM), typically by nonactin for the NH4 + recognition. Herein, we report a Prussian blue analogue of copper(II)-hexacyanoferrate (CuHCF) for an ISM-free potentiometric NH4 + sensor without using the ionophores. CuHCF works as a bifunctional transducer that could realize the ion-to-electron transduction and NH4 + recognition. CuHCF exhibits competitive analytical performances regarding traditional nonactin-based SC-ISEs of NH4 +, particularly for the selectivity toward K+. The cost and preparation process have been remarkably reduced. The theoretical calculation combined with electrochemical tests further demonstrate that relatively easier intercalation of NH4 + into the lattices of CuHCF determines its selectivity. This work provides a concept of the ISM-free potentiometric NH4 + sensor beyond the nonactin ionophore through a CuHCF bifunctional transducer.

“…With the burgeoning focus on the potential applications of metal–organic frameworks (MOFs) in multifarious fields recently, Prussian blue (PB) and Prussian blue analogues (PBAs), an extremely easily available subcategory among 20,000 MOFs, re-enter into people’s horizons. − Despite the span of PB over three centuries, just over the past one and a half years from 2021 to October 2022, there have been 29 published reviews recorded in Web of Science on the synthesis techniques and applications of PB/PBAs mainly related to energy storage and conversion, − catalysis, − and electrochemical sensors. , In particular, because of their advantageous features including the low-cost, environmental benignity, open framework, compositional control, excellent redox activity, high cycling stability, and highly reversible phase transitions of PB/PBAs-based electrodes, PB/PBAs have been extensively explored as promising active materials in electrochemical applications such as energy storage devices, electrocatalysis, and sensors in the last decade. ,,,− Nevertheless, the poor conductivity of PB/PBAs with cyanide bridges frequently frustrates their practicability in the electrochemistry-related applications, and compositing highly conductive materials such as carbon materials is the simplest way for facilitating electron transfer and enhancing electrochemical kinetics. , …”

Disruptive Strategy To Fabricate Three-Dimensional Ultrawide Interlayer Porous Carbon Framework-Supported Prussian Blue Nanocubes: A Carrier for NiFe-Layered Double-Hydroxide toward Oxygen Evolution

We, for the first time, offer a unique and disruptive strategy to prepare N-doped three-dimensional porous carbon framework-supported well-defined Fe4[Fe(CN)6]3 nanocubes (indicated as PB@N-PCFs). The carbon frameworks hold an ultrawide interlayer spacing of 0.385–0.402 nm for the (002) planes of graphite and ultrahigh graphitization. Furthermore, PB@N-PCFs are used as a carrier to grow NiFe-layered-double-hydroxide nanosheet arrays (denoted as NiFe-LDH/PB@N-PCFs) in situ, where the interlayer spacing for the (002) planes of graphite can be expanded as high as 0.457 nm in the carbon frameworks. Moreover, NiFe-LDH/PB@N-PCFs shows excellent electrocatalytic performance toward oxygen evolution in terms of activity, kinetics, and durability, elegantly rivaling the state-of-the-art RuO2. More profoundly, after 3000 cycle cyclic voltammetry scans, NiFe-LDH/PB@N-PCFs still display far more desirable activity with respect to initial NiFe-LDH/PB@N-PCFs. We believe that the PB@N-PCFs and PB@N-PCFs-based composites with ultrahighly graphitized and large interlayer spacing N-PCFs can find more places in electrochemistry-related applications such as Na/K-ion batteries, electrocatalysis, and electrochemical sensors.
