This personal account presents our systematic development of redox cycling-based amplification strategies to overcome this challenge. Starting with enzyme-amplified electrochemical–chemical cycling, we progressed to chemical–chemical and EC–chemical systems, enabling repeated utilization of enzymatically generated electroactive species. Mechanistic insights into electron-transfer pathways (i.e. inner sphere-philic and outer sphere- philic nature) guided the rational selection of enzyme substrates, redox mediators, and oxidant–reductant pairs. Integrating alkaline phosphatase–catalyzed reactions with multistep redox cycling substantially enhanced signal-to-background ratios and detection limits without complex electrode modification. Hydroquinone diphosphate-based systems offered superior performance due to favorable redox properties and stability. Besides, with enzyme mediated electrochemical-enzymatic cycling, we progressed to EC–enzymtic systems, enzyme itself is redox active. These approaches enabled ultrasensitive detection of protein biomarkers at femtogram-per-milliliter levels and reliable quantification of pathogenic bacteria. The account also addresses challenges in background suppression, reagent stability, and assay reproducibility, providing general design principles for robust, scalable, and sustainable electrochemical biosensors.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":"26 8","pages":""},"PeriodicalIF":8.9,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148013842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review presents a multilevel framework to overcome these barriers. At the macroscopic solid–liquid–gas boundary, bio-inspired and asymmetric wettability architectures enable the decoupling of gas and ion transport channels, thereby alleviating diffusion-limited current scaling. At the atomic level, defect engineering, size control, heteroatom doping and synergistic heterointerface construction regulate local electronic structure and oxygen intermediate adsorption. Beyond intrinsic material design, external physical fields act as dynamic levers, ranging from magnetohydrodynamic enhancement of bubble detachment to magnetic exchange interactions for spin alignment. We further highlight chiral spintronics, where the chiral-induced spin selectivity effect provides an intrinsic field-free route for spin filtering. By promoting parallel spin alignment of radical intermediates, intrinsic chirality facilitates triplet oxygen formation. Finally, we integrate these multilevel strategies to outline a path toward next-generation oxygen electrocatalysts, while identifying critical challenges in stability, spin-sensitive operando characterization, standardized evaluation, and practical scalability.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":"26 8","pages":""},"PeriodicalIF":8.9,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148052947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this endeavor, mixed matrix membranes (MMMs), which synergistically integrate polymer matrices with functional nanofillers (e.g., metal–organic frameworks (MOFs), covalent organic frameworks (COFs), graphene oxide (GO), clay, etc.), have emerged as a frontier in CO2 separation. Among the diverse spectrum of nanofillers, MXenes, a class of 2D transition metal carbides, nitrides, and carbonitrides, stand out for their tunable layered structure and rich surface functional groups. These features enable molecular sieving pathways, improve polymer–filler interfacial compatibility, reduce agglomeration, and optimize membrane morphology. In this review, the progress of MXene-based MMMs for CO2 separation is critically examined, with an emphasis on structural characteristics, synthesis techniques, CO2 transport mechanism, and underpinning interfacial dynamics.

With worsening freshwater scarcity, water pollution, and 80% of wastewater worldwide containing high TDS, heavy metals, and inorganic and organic contaminants, the need to obtain freshwater from nonfreshwater sources is essential. Capacitive deionization (CDI) is an emerging, promising electrochemical technique that offers robustness, cost-effectiveness, and high efficiency. CDI is a cost- and energy-efficient alternative for applications such as desalination and the elimination of heavy or radioactive metals. This review discusses the general concepts of CDI, including different cell designs, adsorption and desorption cycles, and evaluation parameters, to provide a foundation. Later, we describe the potential of metal–organic frameworks (MOFs) as electrode materials for CDI, the recently reported modifications and developments in MOF-based electrode materials, their CDI performance, and the underlying mechanisms for desalination and ion capture. This review concludes with future perspectives for further developments in the field of capacitive deionization.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":"26 8","pages":""},"PeriodicalIF":8.9,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148136724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This potential can be attributed to their notable advantages, which include the decoupling of power and capacity, a prolonged cycle life, and a high level of safety. However, the enhancement of their energy efficiency and power density remains significantly constrained by critical issues, including sluggish reaction kinetics, the shuttle effect of active species, and inadequate interfacial stability. In recent years, heterojunctions have emerged as an efficient interfacial engineering strategy, providing novel solutions for enhancing the key performance of RFBs. This enhancement is achieved through the reconstruction of the interfacial electronic structure and modulation of the built-in electric field. This study provides a comprehensive review of the research progress related to heterojunctions in RFBs. The study focuses on summarizing the construction strategies and action mechanisms of heterojunction electrodes and heterojunction ion exchange membranes. It also discusses the regulatory effects of these materials on redox reaction kinetics, ion transport behavior, and cycling stability of RFBs.

It is essential to address these issues without compromising high gravimetric and volumetric energy densities for the commercialization of Li-S batteries. Furthermore, although Li-S batteries perform well at ambient temperatures, achieving reliable operation across wider temperature ranges remains challenging, which is crucial for future mission-specific applications. This review delves into advanced design strategies for sulfur cathodes of Li-S batteries, evaluating their influence on gravimetric energy density (Wh kg-1), volumetric energy density (Wh L-1), and wide-temperature performance. The key parameters of the sulfur cathode significantly relevant to practical application are discussed, including sulfur fraction, sulfur loading, electrolyte-to-sulfur ratio (E/S ratio), and the density of host materials. The aim is to bridge the gap between fundamental research and the practical realization of high-performance Li-S batteries.

This comprehensive review critically analyzes the latest progress, persistent challenges, and future opportunities of 2D materials for advanced TE applications. We begin by systematically evaluating the synthesis and processing toolkit, correlating techniques from top-down exfoliation to bottom-up chemical vapor deposition with their specific impacts on microstructure and final device performance. Subsequently, we provide a critical assessment of the fundamental TE performance of key 2D families, including graphene, transition metal dichalcogenides (TMDs), MXenes, black phosphorus (BP), and hexagonal boron nitride (h-BN). The discussion details how advanced engineering strategies, such as strain modulation, layer number control, chemical doping, and heterostructure (HS) design, can dramatically enhance the power factor (PF) while simultaneously suppressing lattice thermal conductivity (κL).
