Special Issue Information

Dear colleagues,

The rapid global economic growth has created a series of ecological, social, and technological challenges that are related to the gradual dispersion of natural resources as well as to the increasingly difficult access to drinking water. In the face of climate change and the forced development of modern technologies that facilitate environmental protection and maintain or improve the current standard of living, these challenges will become more and more important.

These issues can be addressed by considering the potential of functional polymeric and composite materials. These materials can offer unique properties, depending on their composition, morphology, and functionalities they contain. In particular, different functional groups can provide ion exchange, chelating, catalytic, sensing, as well as reducing and stabilizing features, also enabling the fabrication of nanocomposite materials. These properties, useful in separation science and catalysis, include the possibilities of recovering transition group metals for the manufacturing of modern devices, removing contaminants that prevent the direct use of water, and facilitating the separation or decomposition of toxic pollutants discharged into the environment by various sectors of the chemical industry. In this context, polymers and composites can be recognized as highly versatile and tunable materials.

We would like to invite scientists to contribute to this Special Issue focused on functional materials for environmental protection. Research topics of interest include, but are not limited to, recent advances in the synthesis and/or application of polymers and (nano)composites designed for separation and catalysis, with emphasis on issues related to environmental protection and sustainable development. Both original articles and reviews are very welcome.

The present work presents a new nanocomposite catalyst with rhenium nanostructures (ReNSs) for the catalytic hydrogenation of 4-nitrophenol and 4-nitroaniline. The catalyst, based on an anion exchange resin with functionality derived from 1,1′-carboimidazole, was obtained in the process involving anion exchange of ReO4– ions followed by their reduction with NaBH4. The amino functionality present in the resin played a primary role in the stabilization of the resultant ReNSs, consisting of ≈1% (w/w) Re in the polymer mass. The synthesized and capped ReNSs were amorphous and had the average size of 3.45 ± 1.85 nm. Then, the obtained catalyst was used in a catalytic reduction of 4-nitrophenol (4-NP) and 4-nitroaniline (4-NA). Following the pseudo-first-order kinetics, 5 mg of the catalyst led to a 90% conversion of 4-NP with the mass-normalized rate constant (km1) of 6.94 × 10−3 min−1 mg−1, while the corresponding value acquired for 4-NA was 7.2 × 10−3 min−1 mg−1, despite the trace amount of Re in the heterogenous catalyst. The obtained material was also conveniently reused. Full article

The membrane emulsification process (ME) using a metallic membrane was the first stage for preparing a spherical and monodisperse thermoresponsive molecularly imprinted polymer (TSMIP). In the second step of the preparation, after the ME process, the emulsion of monomers was then polymerized. Additionally, the synthesized TSMIP was fabricated using as a functional monomer N-isopropylacrylamide, which is thermosensitive. This special type of polymer was obtained for the recognition and determination of trace bisphenol A (BPA) in aqueous media. Two types of molecularly imprinted polymers (MIPs) were synthesized using amounts of BPA of 5 wt.% (MIP-2) and 7 wt.% (MIP-1) in the reaction mixtures. Additionally, a non-imprinted polymer (NIP) was also synthesized. Polymer MIP-2 showed thermocontrolled recognition for imprinted molecules and a higher binding capacity than its corresponding non-imprinted polymer and higher than other molecularly imprinted polymer (MIP-1). The best condition for the sorption process was at a temperature of 35 °C, that is, at a temperature close to the phase transition value for poly(N-isopropylacrylamide). Under these conditions, the highest levels of BPA removal from water were achieved and the highest adsorption capacity of MIP-2 was about 0.5 mmol g−1 (about 114.1 mg g−1) and was approximately 20% higher than for MIP-1 and NIP. It was also observed that during the kinetic studies, under these temperature conditions, MIP-2 sorbed BPA faster and with greater efficiency than its non-imprinted analogue. Full article

Herein, a synthetic strategy for a rough microsphere Cr(VI)-adsorbent via the reaction of tannic acid (TA) and 1,6-hexanediamine (HA) and using polyethylene glycol (PEG) as surface modifier was presented. This adsorbent was characterized by a Fourier Transform Infrared spectrometer (FTIR), thermogravimetic analysis (TGA), X-ray photoelectron spectroscopy (XPS), etc. Certain factors, including contact time, PEG@poly(tannin-1,6-hexanediamine) (PEG@PTHA) dosage, initial concentration, and experimental temperature affecting the Cr(VI) adsorption performance of adsorbent were explored. PEG@PTHA can adsorb Cr and the Cr(VI) was reduced up to Cr(III) due to the existence of phenolic hydroxyl groups. Its adsorption capacity can reach up to 300 mg/g within 10 min and approximately 100% removal percentage below the initial concentration of 100 mg/L. Its behavior matched well with the Langmuir isotherm model and pseudo-second-order kinetic model. A PEG@PTHA adsorbent with maximum adsorption capacity (450 mg/g) has great prospects in Cr(VI)-sewage treatment. Full article
