However, their practical deployment is still restricted by severe capacity fading caused by Jahn–Teller-induced structural instability and sluggish Zn2+ transport in the cathode. Although surface coating, heteroatom doping, and structural regulation have been widely explored to improve Mn-based cathodes, these approaches may suffer from increased interfacial resistance, compositional complexity, or limited control over the intrinsic electronic structure. In this context, oxygen-vacancy engineering offers a more direct route to modulate local coordination environments and accelerate Zn2+/H+ storage kinetics. Herein, lattice-level defect engineering of a dense Mn2O3 host is achieved through a metal–organic framework-derived synthesis followed by mild secondary annealing. The introduced oxygen vacancies regulate the local electronic structure and coordination environment, thereby facilitating Zn2+ diffusion, accelerating charge-transfer kinetics, and improving electrochemical reversibility. Combined experimental and theoretical investigations further show that oxygen-vacancy engineering enhances electronic conductivity, reduces the Zn2+ migration barrier, and enables a reversible dual-ion storage mechanism involving both H+ and Zn2+. Benefiting from these effects, the Zn‖Vo-Mn2O3 battery delivers a high specific capacity of 359 mAh g−1 at 0.3 A g−1, maintains 210 mAh g−1 at 6 A g−1, and retains 74.3% of its capacity after 10 000 cycles at 12 A g−1 after only 150 s of initial preconditioning. This work highlights oxygen-vacancy engineering as an effective route to enhancing the kinetic and structural stability of Mn-based cathodes for advanced AZIBs.","lang":"eng"}],"date_updated":"2026-10-06T10:34:27Z","OA_type":"closed access"},{"page":"16706 - 16713","volume":4,"abstract":[{"text":"The development of highly active, low cost and stable electrocatalysts for direct alcohol fuel cells remains a critical challenge.

In such applications, the use of solution-processed nanocrystals (NCs) to produce thin films or bulk nanomaterials has associated several potential advantages, such as high material yield and throughput, and composition control with unmatched spatial resolution and cost. Here we report on the production of Cu3SbSe4 (CASe) NCs with tuned amounts of Sn and Bi dopants. After proper ligand removal, as monitored by nuclear magnetic resonance and infrared spectroscopy, these NCs were used to produce dense CASe bulk nanomaterials for solid state TE energy conversion. By adjusting the amount of extrinsic dopants, dimensionless TE figures of merit (ZT) up to 1.26 at 673 K were reached. Such high ZT values are related to an optimized carrier concentration by Sn doping, a minimized lattice thermal conductivity due to efficient phonon scattering at point defects and grain boundaries, and to an increase of the Seebeck coefficient obtained by a modification of the electronic band structure with Bi doping. Nanomaterials were further employed to fabricate ring-shaped TE generators to be coupled to hot pipes, which provided 20 mV and 1 mW per TE element when exposed to a 160 °C temperature gradient. The simple design and good thermal contact associated with the ring geometry and the potential low cost of the material solution processing may allow the fabrication of TE generators with short payback times."}],"volume":5,"page":"2592 - 2602","OA_type":"closed access","date_updated":"2026-05-13T13:12:04Z","intvolume":"         5","extern":"1","publist_id":"7457","publisher":"Royal Society of Chemistry","type":"journal_article","year":"2016","language":[{"iso":"eng"}],"oa_version":"None","fulldoi":"https://doi.org/10.1039/C6TA08467B","publication_status":"published","article_processing_charge":"No","title":"Solution based synthesis and processing of Sn and Bi doped Cu inf 3 inf SbSe inf 4 inf nanocrystals nanomaterials and ring shaped thermoelectric generators","_id":"370","publication_identifier":{"issn":["2050-7488"],"eissn":["2050-7496"]},"date_created":"2018-12-11T11:46:05Z"},{"citation":{"ieee":"X.

For photocatalytic water splitting, the CuInS2 bandgap is slightly too low to efficiently overcome the reaction over-potential. The presence of Ga shifts up the CuInS2 conduction band edge providing a larger driving force for photogenerated carriers to activate the water splitting reduction reaction. The larger the Ga content, the more energetically favorable the electron injection, and thus a more efficient use of the photogenerated carriers is reached. However, the band gap increase associated with the Ga incorporation reduces the concentration of photogenerated carriers available for water splitting, and consequently a lower hydrogen conversion rate is obtained for very high Ga contents.
