In this study, we developed a multifunctional nanoplatform to address the limitations of strictly acidic pH for the Fenton reaction involving FeO and the low efficiency of mono treatments. The hybrid material, FeO@Cu-TCPP, was assembled through hydrophobic interactions of polyvinylpyrrolidone (PVP) coated on its surface. The efficiency of the Fenton reaction using FeO was significantly enhanced by the photo-Fenton process in the presence of Cu-TCPP.

Designing advanced materials that effectively mitigate the poor cycle life of battery-type electrodes with high specific capacities is crucial for next-generation energy storage systems. Herein, graphene oxide-ceria (GO-CeO) nanocomposite synthesized via a facile wet chemical route is explored as cathode for high-performance supercapacitors. The morphological analysis suggests fine ceria (CeO) nanoparticles dispersed over ultrathin graphene oxide (GO) sheets while structural studies reveal face-centered cubic phase of CeO in the nanocomposite.

The transformation of bulk transition-metal dichalcogenide (TMD) particles into ultrathin nanosheets with both an acceptable yield and preserved crystalline integrity presents a substantial challenge in electrochemical exfoliation. This challenge arises from the continuous potential stress that the materials experience in traditional exfoliation setups. Herein, we propose a new fluidized electrochemical exfoliation (FEE) method to efficiently transform TMD powders into high-quality, few-layered TMD nanosheets in the aqueous phase.

The present work reports a clear and improved hydrothermal methodology for the synthesis of MoSe nanoflowers (MNFs) at 210 °C. To observe the effect of temperature on the fascinating properties, the process temperature was modified by ±10 °C. The as-prepared MNFs were found to consist of 2D nanosheets, which assembled into a 3D flower-like hierarchical morphology van der Waals forces.

The development of efficient photocatalysts inspired by natural photosynthesis has drawn considerable interest for sustainable hydrogen (H) production. Among the various strategies for enhancing H evolution, constructing step-scheme (S-scheme) heterojunctions has attracted extensive interest, thanks to their limited charge recombination and enhanced charge transport in comparison to the traditional photocatalytic systems. Herein, we report the engineering of a novel S-scheme heterojunction by integrating ultrathin ZnInS (ZIS) nanosheets with MOF-derived N-doped NiO porous microrods (ZIS/N-NiO) toward superior photocatalytic behaviors.
