Nanoconfinement at the interface of heterogeneous Fenton-like catalysts offers promising avenues for advancing oxidation processes in water purification. Herein, we introduce a template-free strategy for synthesizing nanoconfined catalysts from municipal sludge (S-NCCs), specifically engineered to optimize reactive oxygen species (ROS) generation and utilization for rapid pollutant degradation. Using selective hydrofluoric acid corrosion, we create an architecture that confines atomically dispersed Fe centers within a micro-mesoporous carbon matrix in situ.

Developing versatile, scalable, and durable coatings that repel various matters in different service environments is of great importance for engineered materials applications but remains highly challenging. Here, the mesoporous silica microspheres (HMS) fabricated by the hard template method were utilized as micro-nanocontainers to encapsulate the hydrophobic agent of perfluorooctyltriethoxysilane (F13) and the corrosion inhibitor of benzotriazole (BTA), forming the functional microsphere of F-HMS(BTA). Moreover, the synthesized organosilane-modified silica sol adhesive (SMP) and F-HMS(BTA) were further employed as the binder and functional filler to construct a superhydrophobic self-healing coating of SMP@F-HMS(BTA) on various engineering metals through scalable spraying.

Research on stimuli-responsive micro-nanocontainers has gained attention for targeted corrosion inhibition and controlled emulsification-demulsification in oil recovery. However, existing nanocontainers face issues like irreversible drug release and limited functionality. This study presents a multi-functional nanocontainer design with reversible drug release and emulsification-demulsification capabilities.

Design and manufacture of cathode materials, with suitable pore structure and high electrical conductivity to matching zinc anode, solving the problem of dissolution and structural degradation of cathode materials for zinc ion batteries (ZIBs), is great significance to the development of ZIBs. Herein, Vanadium Nitride (VN) uniformly decorated N-doped micro/mesoporous carbon nanofibers (VN/N-MCNF) with appropriate porous and reactive sites for Zn is prepared by using V-MOF, as important precursor via electrostatic spinning and pyrolysis technique. As a cathode electrode for ZIBs, the VN/N-MCNF is suitable for diffusion and adsorption of large-sized solvated structured [Zn(HO)], for its abundant micro/mesoporous structure and good electrical conductivity.

The textural properties of synthetic and natural clays in the sodium form and exchanged with tetramethylammonium cations (TMA) were characterized using N and Ar physisorption isotherms at cryogenic temperatures. Specific surface areas and micro/mesoporous volumes were determined using the BET and the models. The analysis requires the use of reference isotherms measured at the same temperature on the surface of non-porous materials with an identical chemical composition.
