This review provides a comprehensive overview of the recent research progress on TiSe2-based thermoelectric materials. First, the fundamental structural features and intrinsic thermoelectric properties of TiSe2 are summarized, including its layered crystal structure, charge density wave (CDW) transition, and intrinsic transport behaviors. Subsequently, various modulation strategies to enhance its thermoelectric performance are systematically discussed, such as chemical doping or intercalation, strain engineering, defect engineering, and heterostructure construction. The underlying mechanisms of performance enhancement, including band-structure optimization, carrier-concentration regulation, and lattice thermal conductivity reduction, are elaborated. Notably, a recently reported dual-chemical strategy that simultaneously modifies intralayer bonding and interlayer charge dynamics is discussed in detail, as it yields an exceptionally high thermoelectric figure of merit (ZT) of 0.82 in Cu0.8CrTi2Se6. This result underscores the potential of coordinated modulation strategies, although continued exploration of alternative dopant combinations and validation by independent groups remain important for establishing general design principles. Furthermore, the latest advances in TiSe2-based thermoelectric devices are briefly introduced. Finally, the current challenges and future development directions of TiSe2 thermoelectric materials are prospected, aiming to provide guidance for the design and optimization of high-performance TiSe2-based thermoelectric systems.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147708262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The layered accordion-like nanoarchitecture facilitates rapid mass transport and efficient charge transfer, enabling signal amplification in electrochemical sensing. Further conjugation of biorecognition elements (BREs) enhances the specificity and selectivity of the analytical interface. In this work, nanoengineered MXenes have been explored as tunable analytical interface for real-time biochemical marker analysis.

Cobalt oxide is selected as the oxide support, synthesized by the solution combustion method, upon which copper nanoparticles are dispersed using the formaldehyde reduction method.

Detailed catalyst characterizations are performed using X-ray diffractometer, field emission scanning electron microscopy, inductively coupled plasma optical emission spectrometer, high-resolution transmission electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy analyses. Electrochemical studies are carried out to estimate the catalyst's activity using techniques such as cyclic voltammetry and chronoamperometry.

However, traditional nanoframes are known to suffer from poor structural robustness because of their ultrathin ridges. Here, we address this issue by developing a new class of nanoframes characterized by relatively thick but hollow ridges. Our demonstration is based upon Pd and a typical synthesis involves the one-shot injection of PdBr2 powder suspension into an aqueous mixture containing Ag nanocubes, ascorbic acid, poly(vinyl pyrrolidone), and KBr held at 75°C. The poor solubility of PdBr2 in water enables slow release of Pd(II) and thus a steady reduction rate for controlling the deposition of Pd atoms. During the synthesis, the side faces of Ag nanocubes are continuously carved away through galvanic replacement, accompanied by the deposition of Pd atoms on the corners and edges for the generation of cage cubes—cubes with through holes across the opposite faces. At a later stage, the Ag remaining in the ridges is etched away, leading to the formation of hollow ridges with a final composition of Pd1Ag2. The Pd–Ag alloy nanoframes exhibited good structural robustness during 1 h of chronoamperometric test toward formic acid oxidation reaction.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://aces.onlinelibrary.wiley.com/doi/epdf/10.1002/cnma.202500773","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By integrating molecular electrostatic potential mapping, K+/K adsorption energetics, adsorption-derived operating voltages, optimized adsorption geometries, and HOMO–LUMO characteristics, we established a unified framework linking electrostatic modulation to thermodynamic balance and structural accommodation.

F doping induced pronounced nonplanarity and a compliant adsorption pocket that enhances out-of-plane accommodation of both K+ and K. In multi-doped systems, N/O and O/F exhibited complementary role sharing that stabilizes adsorption and K+→ K conversion, while N/F revealed a trade-off without O.
