However, the heavy shuttle effect of polysulfides and the growth of lithium dendrites greatly hinder their further development and commercial application. In this paper, cobalt-molybdenum bimetallic carbides heterostructure (Co₆Mo₆C₂@Co@NC) was successfully prepared through chemical etching procedure of ZIF-67 precursor with sodium molybdate and the subsequent high temperature annealing process. The obtained dodecahedral Co₆Mo₆C₂@Co@NC with hollow and porous structure provides large specific surface area and plentiful active sites, which speeds up the chemisorption and catalytic conversion of polysulfides, thus mitigating the shuttle effect of polysulfides and the generation of lithium dendrites. When applied as the LSBs separator modifier layer, the cell with modified separator present excellent rate capability and durable cycling stability. In particular, the cell with Co₆Mo₆C₂@Co@NC/PP separator can maintain the high capacity of 738 mAh/g at the current density of 2 C and the specific capacity of 782.6 mAh/g after 300 cycles at 0.5 C, with the coulombic efficiency (CE) near to 100%. Moreover, the Co₆Mo₆C₂@Co@NC/PP battery exhibits the impressive capacity of 431 mAh/g in high sulfur loading (4.096 mg/cm²) at 0.5 C after 200 cycles. This work paves the way for the development of bimetallic carbides heterostructure multifunctional catalysts for durable Li-S battery applications and reveals the synergistic regulation of polysulfides and lithium dendrites through the optimization of the structure and composition.</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 7","pages":"Article 110604"},"PeriodicalIF":9.4,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142562363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this challenge, we propose a novel draining anti-adhesion dressings (DAD) by constructing the hydrophilic microchannels array on the superhydrophobic dressing. The superhydrophobic areas facilitate stable wound fluid repellence leading to achieve the anti-adhesion (18.7 % detachment energy of cotton) and the microchannel array ensures the transportation of excess exudates (&gt;92 %) by the capillary force.

Meanwhile, the toxic nature and potential health hazards of BTX gases cannot be ignored due to low-concentration leaks underline the critical need for rapid and real-time monitoring of these gases. Chemiresistive metal oxide semiconductor (MOS)-based gas sensors, which are extensively used for gas detection in both industrial settings and everyday life, emerge as one of the optimal solutions for trace BTX detection. These sensors are highly valued for their high sensitivity and low detection limits. Nevertheless, the improvement of selectivity towards specific BTX gases to achieve efficient and precise detection still remains challenging. This review summarizes the chemiresistive MOS-based gas sensors designed for BTX detection, categorizing them based on the components of sensing materials-basically into three groups: single-component, single heterojunction, and multiple heterojunctions gas sensing materials. Further, the review proposes the future application prospects of chemiresistive MOS-based BTX gas sensors, with specific emphasis on their significance in promoting industrial safety and environmental monitoring.","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"87 1","pages":""},"PeriodicalIF":9.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142562369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we present an operational, robust, safe and cost-effective catalytic system for hydrogen storage and liberation. We have established a unique catalytic system with two different solid organometallic assemblies (NHC-Ru and NHC-Ir) that facilitate the reversible transformation between sodium formate and bicarbonate in aqueous solutions collaboratively and efficiently. Notably, the NHC-Ru catalyst is privileged for the hydrogenation of sodium bicarbonate, whereas the NHC-Ir component enables the dehydrogenation of sodium formate, all in a single reaction vessel. What sets this system apart is its simplicity. The H₂ discharging and recharging is simply regulated by heating the mixture with or without H₂. Remarkably, this process requires no extra additives or supplementary treatments. Moreover, the reversible hydrogen storage system is durable and can be reused for over 30 cycles without a discernible decline in activity and selectivity.
