The development of a multi-dimensional hierarchical architecture has proven to be an effective approach to address the limitations associated with sulfides. In the present study, MoNiCo-S nanorods featuring hierarchical micro-/nano-structures were successfully synthesized through a straightforward methodology that involved \"in situ growth-etching-vulcanization\". The one-dimensional nanostructure CoMoO4 served as both the substrate and metal source for the in-situ growth of ZIF-67. Subsequently, Lewis acid was introduced to facilitate the formation of hydroxides, ultimately leading to the synthesis of sulfides via ion exchange with sulfur ions. Due to its rational design and element composition, MoNiCo-S exhibited excellent capacitance (3125.1 F/g at 1 A/g) and cycling stability (capacitance retention rate of 72.9 % over 5,000 cycles). In addition, the broad bean shell derived carbon (KBBC), prepared through a carbonization and activation process, demonstrated a specific capacitance of 295.0 F/g and a cyclic capacitance retention of 99.6 %. The assembled MoNiCo-S//KBBC asymmetric supercapacitor devices achieves a high energy density of 78.5 Wh kg-1 at a power density of 1004.3 W kg-1. After 10,000 cycles, the device exhibited a capacitance retention rate of 107.9 %, indicating excellent cycling stability.

Self-assembled lipid structures are already used in a variety of industries including cosmetics, drug delivery and as microreactors. However, most research into lipid self-assembly has been limited to aqueous solvents. This paper explores the self-assembly of a well-known lipid, phytantriol, in different deep eutectic solvents composed of choline chloride with urea, glycerol, or ethylene glycol, and one composed of betaine and glycerol. High-throughput small angle X-ray scattering was employed to examine self-assembly of this lipid in these deep eutectic solvents, and in mixtures with water from 25 to 66 °C. Choline chloride:urea and neat betain:glycerol supported complex phase formation including the Pn3m cubic phase, and an inverse hexagonal (HII) phase, while choline chloride:glycerol and choline chloride:ethylene glycol favoured amorphous or unstructured lipid assemblies. In all cases, water contents above 50 wt% favoured the formation of highly structured phases. These results demonstrate that deep eutectic solvents can support lipid assembly, but also that small changes to the solvent can lead to significant changes in lipid behaviour. This provides an avenue for solvent-controlled tailoring of lipid structures as well as a mechanism for targeted release of cargo, such as through simple addition of water to trigger a phase change. These results provide significant new insight into solvent-controlled lipid self-assembly with far-reaching applications.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"684 Pt 2","pages":"277-286"},"PeriodicalIF":9.4,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142997801","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}

However, the study of electrocatalysts grounded solely on free energy calculation often lacks in-depth analysis, particularly overlooking the influence of solvent and electrode potential. In this regard, we here present a novel approach using constant-potential and ab initio molecular dynamics (AIMD) simulation to screen single-atom catalysts loaded on transition metal dichalcogenides (SA@TMDs) for ORR. An extensive investigation of 1584 SA@TMDs results in 20 high performing ORR catalysts with overpotential less than 0.33 V and high working stability. In addition, our study shows that the electrode potential has different effects on the adsorption energy of *OOH, *O and *OH, which leads to a reversal of the rate-determining step (RDS) of the ORR. This work presents not only credible, high-performance catalyst candidates for experimental exploration, but also significantly improves our understanding on the reaction mechanism of ORR under realistic reaction conditions.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"684 Pt 2","pages":"251-261"},"PeriodicalIF":9.4,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142997750","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}

In this study, we have successfully fabricated a nanofibrous Ru/SnO2 heterostructure that demonstrates exceptional performance in both hydrogen evolution reaction (HER) and HzOR. The obtained catalyst requires only a small overpotential of 39 mV for HER and an incredibly low potential of -0.076 V vs. reversible hydrogen electrode (RHE) for HzOR to generate the current density of 10 mA cm-2. Furthermore, the two-electrode overall hydrazine splitting (OHzS) cell operates at working voltages of 0.026 V and 0.292 V for the current densities of 10 mA cm-1 and 100 mA cm-2, respectively, notably lower than the overall water splitting (OWS) process.

On the one hand, the introduction of Sb-ion in interior of grains can generate Sb-O chemical bond with high dissociation energy, which contributes to reinforce the chemical and structural stability. Meanwhile, the existence of Sb-ions can restrain the harmful H2-H3 phase transformation and expand interlayer spacing, thereof enabling to weaken the mechanical stress and enhance ion diffusion rate. On the other hand, the surficial modification resulted by the Sb-based materials can effectively suppress the noxious interfacial reaction, which is conducive to improving the cycling stability.

However, the applications of NFM are restricted owing to detrimental interfacial side reactions and phase evolution during cycling. Herein, a three-in-one modification strategy, including Na2MoO4 coating, surface reconstruction from layered to spinel phase, and Mo6+ doping, is proposed to design NFM. A uniform and tight Na2MoO4 coating layer formed via reactive wetting mechanism can effectively inhibit the unfavorable side reactions between cathode and electrolyte. The formation of nanoscale spinel layer can anchor the interior layered structure, leading to a decrease in volume change during the sodiation/desodiation process. The incorporation of Mo6+ with a high valence state and strong MoO bonds into the O3 phase promotes the expansion of transition-metal layer spacing and enhances the structural stability. As a result, tri-modified NFM exhibits superior cycling stability with a capacity retention of 85.20 % after 300 cycles at 100 mA g-1 and rate performance with a discharge capacity of 56.9 mAh/g at 2000 mA g-1, outperforming those of pristine NFM (61.76 % and 39.4 mAh/g).
