Introduction to Porous Nanocomposites

Multifunctional magnetic mesoporous nanocomposites are promising materials to remove the various pollutants from water due to the remarkable properties such as multiple binding sites, high surface area, and magnetic separation.

These results offer insights into the design of mesoporous nanocomposites for developing high-performance LIC.

It is found that the adsorption of mesoporous nanocomposites for horseradish peroxidase (HRP) is pH dependent, and the high binding capacity toward HRP is mainly based on catecholic anchoring at pH ≤ 8.

Recently, it has been observed that silver-based porous nanocomposites (AgNCs) were efficiently deactivated the bacteria and viruses up to 99%–100% from drinking water.

To test the availability of the mesoporous nanocomposites as photocatalysts, they were submitted to UV light for methylene blue photobleaching, used as a model waste compound.

The porous nanocomposites with multilevel structures have been synthesized by using petrochemical waste water (PWW) as the organic ligands of iron metal–organic frameworks (Fe-MOFs) precursor and the sources of sulfur, nitrogen and carbon.

In-situ growth of zeolite imidazolate frameworks (ZIFs) on the surface of layered double hydroxides (LDHs) for preparation of porous nanocomposites is a favorable strategy to design potential materials in separation fields.

Specifically, gold/zinc oxide (Au/ZnO)-based porous nanocomposites are formed in situ by a two-step process.

Some favorable electrochemical performances in specific capacity, cycling performance, and rate capability are achieved using the porous nanocomposites as an anode for lithium-ion batteries.

However, conventional solid or porous nanocomposites based on nanoparticle-type materials have significant problems such as a high aggregation tendency, low percolation ratio and low mass transport, which cause a fatal degradation of the mechanical, thermal and electrical performance.

This comprehensive information provides not only a great understanding of the regulation mechanism of core–shell mesoporous nanocomposites, but also a further useful modification of the composites with high selectivity for 2,4,6-TCP.

These findings present new possibilities to design inexpensive and porous nanocomposites based on metal chalcogenides and functionalized carbon-derived matrices.

A range of architectures have been prepared via single-micelle assembly, for example, single-micelle porous liquids, single-layered mesoporous nanosheets, single-crystal mesoporous nanoparticles and Janus mesoporous nanocomposites.

In this work, a size-exclusive magnetic binary metal mesoporous nanocomposites were synthesized to capture phosphorylated peptides for mass spectrometry analysis.

By manipulating the number of nucleation sites through mediating surface kinetics, a series of multipods mesoporous nanocomposites with precisely controllable surface topological structures are formed, including Janus with only one pod, nearly plane distributed dual-pods and tri-pods, three-dimensional tetrahedral structured tetra-pods, etc.

CuCo2O4/CuO mesoporous nanocomposites were successfully obtained through one-way reaction and characterized by; x-ray diffraction pattern (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), energy dispersive spectrometry (EDS).

Also the ability of synthesized mesoporous nanocomposites for enzyme immobilization was investigated and results showed that they efficiently immobilized α-amylase enzyme.

Methods/statistical analysis: We report fabrication of mesoporous nanocomposites (Fe–CuS, Cd–CuS, Zr–CuS) with uniform nanostructures via a hydrothermal method employing copper nitrate trihydrate (Cu (NO3).

Mesoporous nanocomposites of POA-TP and Sm@ POA-TP have been characterized by instrumental techniques such as FTIR, XRD, TGA-DTA, SEM, TEM, PL, electron-paramagnetic resonance (EPR) spectroscopies & UV–vis diffuse reflectance spectroscopy (DRS) and their photocatalytic performance were investigated based on the degradation of methylene blue (MB) and malachite green (MG) dyes.

This paper presented the development, fabrication, and characterization of porous nanocomposites using carbon nanofiber (CNF) and polydimethylsiloxane (PDMS) elastomer for sensing applications under compressive loads.

Therefore, BaFe12O19/Al2O3, a magnetic mesoporous nanocomposites, were designed synthesized and characterized using different techniques such as energy dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), Brunauer–Emmett–Teller (BET) adsorption method, and vibrating sample magnetometry (VSM).

The dye removal efficiency was higher than 90% after the first adsorption and remained above 65% after four adsorption–desorption cycles, indicating that the as-prepared magnetic mesoporous nanocomposites can be considered excellent adsorbent materials for the removal of both anionic and cationic dyes from wastewaters, and the recycling performance revealed the stability of MMC.

The obtained results recommend the obtained fluorescent mesoporous nanocomposites as potential candidates for the development of novel probes for the in situ tracking of oxidative stress, as well as for antimicrobial applications.

The porous nanocomposites are characterized to identify key parameters, such as the average pore size, density, porosity and electrical resistivity.
