While their superior thermal properties have been established, their chemical properties on the nanoscale haven't been as well investigated. Herein, the oxidative stability over time under ambient conditions and colloidal stability as function of pH was explored for plasmonic TiN, ZrN, and HfN nanoparticles. It was discovered that the TMN nanoparticles made via solid-state method had a narrow pH stability range between 2–3. Under highly acidic conditions, the particles underwent dissolution and at pH ≥4, they aggregate and precipitate from the solution. Additionally, TiN nanoparticles had poor oxidative stability and oxidized to TiO2 after ~40 days. 3-Aminopropyltriethoxysilane (APTES) and dimethylsilane coated TMNs were synthesized to yield water and organic solvent dispersible particles, respectively. These functionalized colloidal suspensions showed enhanced oxidative stability over 60 days and the APTES coating widened the pH stability window of TMNs to include physiological pH. This study shows that surface functionalization using M−O−Si linkages (where M=Ti, Zr, or Hf) can greatly enhance the stability, dispersibility and therefore applicability of plasmonic TMN nanoparticles.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"10 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnma.202400236","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141568506","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}

Partial reduction of the precursor solution of GO to RGO took place during the solvothermal synthesis at the elevated pressure and temperature conditions. The structural, morphological, and semiconducting characteristics of the obtained binary composites were determined and their capacity of hydrogen production via photocatalytic water splitting in the presence of triethanolamine (TEOA) as sacrificial agent under the simulated solar light irradiation was tested. Photocatalytic experiments have showed that even low mass ratios of R(GO) component (below 1 wt.%) can have a great influence on the photocatalytic activity and properties of the obtained material. The results showed that even a partial reduction of GO to RGO had a positive impact on the photocatalytic properties of the as-prepared materials. The composite with 0.05 R(GO) wt.% achieved the highest H2 generation rate of 139 μmol/h/g and maintained high photostability.

Nevertheless, the application is still hampered by the shuttle effect of soluble lithium polysulfides (LiPSs) intermediates and slow redox kinetics, resulting in irreversible loss of the active material, severe self-discharge and poor cycle stability of the electrode. Therefore, in this work, a novel Mo,N co-doped porous carbon (Mo,N−C) was successfully synthesized by simply calcining a mixture of ramie degumming waste with cost-effective molybdenum salt, and then employed as the LiPSs anchor. Due to the conductive carbon matrix, abundant porous structures as well as the doping Mo and N heteroatoms, the sluggish redox kinetic of the cathode has been significantly improved and the shuttle phenomenon of LiPSs has been effectively inhibited, consequently, the as-prepared Mo,N−C/S-0.4 composite cathode could demonstrate a good initial capacity of 1379.2 mAh g−1 at 0.2 C, and the reversible capacity could remain at 997.5 mAh g−1 after 100 cycles.

Chelation involves the coordination of ligands with Zn2+, offering promising strategies to address challenges such as dendrite formation and hydrogen evolution reactions. However, there is a lack of comprehensive and unified evaluation of chelation‘s protective effect on the zinc anode, which hinders a thorough assessment of chelation‘s effectiveness. Recent studies have demonstrated the excellent protective performance of chelation in altering solvation structures, modifying SEI structures, and selectively adsorbing species on the zinc anode. Furthermore, while chelation demonstrates significant benefits for the zinc anode, its impact on cathode materials must also be considered. Proper selection of chelation strengths and compatible cathode materials is essential for overall battery performance. Future research directions include exploring the effects of different ligands and coordination numbers on battery performance and extending chelation strategies to other secondary metal batteries. Understanding and optimizing chelation mechanisms are critical for advancing the development of high-performance ZIBs and other metal-ion battery technologies.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"10 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141527502","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}
