Tailoring Oil Solubility of 2D Cu(2,6-NDC) Nanosheets via the Solvent Strategy for Synergy-Driven Lubrication in Castor Oil.

Two-dimensional metal-organic frameworks (2D MOFs), particularly those with layered architectures, have emerged as promising candidates for advanced lubrication additives. In this work, we developed a solvent-tuned size strategy to synthesize the Cu(2,6-naphthalenedicarboxylate) (2D Cu(2,6-NDC)) nanosheets with the dimensions of 30-45 nm in thickness, 50-200 nm in width, and 600-1000 nm in length. The characterizations confirmed the structure and composition of the 2D Cu(2,6-NDC) nanosheets.

Diatomite supported highly-dispersed ZnO/Zn-co-embedded ZIF-8 derived porous carbon composites for adsorption desulfurization.

The metal organic framework (MOFs)-derived porous carbon materials with highly dispersed metal active sites were of the exclusive application foreground in many field, such as catalyst, electrochemistry, adsorption desulfurization and so on. However, the loss issue of metal active sites in MOFs frame was indispensable during the high temperature carbonization because of the lower boiling point of many metals, thus fundamentally affecting the atom-scale uniform distribution merit of MOFs-derived porous carbon materials. This work was to provide a novel strategy to address the loss issue of the active metal volatilization in the fabrication of MOFs-derived porous carbon materials.

In Situ Study of Structure-Activity Relationship between Structure and Tribological Properties of Bulk Layered Materials by Four-Ball Friction Tester.

Encouragingly, a lot of research studies have demonstrated that two-dimensional (2D) nanosheets applied as an additive in oils show preferable friction-reducing and wear resistance performance. However, the current issue was that an elusive way could be adopted to probe the structure-activity relationship between the structure and tribological properties of bulk layered materials due to the structural evolution during friction testing. In this study, we studied the structure-activity relationship between the structure and tribological properties of bulk layered materials (graphite, h-BN, WS, and MoS) by an in situ four-ball friction tester.

Electrospinning fabrication for cloth-like carbon nanofiber films with hierarchical porous structure and their application in deep desulfurization.

A strategy for clean fuel by selective adsorption processing was deemed to be convenient and environmental-friendly in past decades. However, the development of adsorption desulfurization was tremendously subject to the fabrication of high-performance adsorbents with large capacity and high stability. Herein, we designed a novel route to fabricate the cloth-like carbon nanofiber film with a hierarchical porous structure by electrospinning.

Ultrasound-assisted Li/Na co-intercalated exfoliation of graphite into few-layer graphene.

In this work, we developed a novel approach for few-layer graphene by employing Li/Na co-intercalated exfoliation assisted by ultrasound method. The experiments were conducted under the ultrasonic power of 300 W and the frequency of 40 kHz without the participation of any organic solvent. The effect of Li/Na proportion on the exfoliation of graphite was intensively investigated.

Ultrasound-Assisted Alkaline Solution Reflux for As-Exfoliated MoS Nanosheets.

A facile approach was developed to produce MoS nanosheets by ultrasound-assisted reflux exfoliation, which was highly efficient for large-scale production and sustainable for environment. The interlayer force of bulk MoS was first exhausted in employing LiOH/NaOH solution by reflux and thereafter quickly exfoliated by ultrasound. The lateral size of the as-prepared MoS nanosheets with about 2-9 layers became smaller.

This original exfoliation was highly efficient for large-scale production and sustainable for the environment.
