“…In the current era, the planet Earth is polluted by various sources which threaten humans and other living organisms for clean resources including food, water, and air. Green chemistry follows a set of rules to avoid the production of toxic substances in various chemical processes [1–3] . The industrial manufacturing protocol, in general, involves multiple chemical processes and produces large quantities of waste as the percentage yield of the desired product formed will be less compared to the precursor materials used.…”

Plastic is an important commodity that is used in several sectors. However, plastic waste generation is a pressing issue and needs attention as it risks the environment. While methods such as landfilling, incineration and recycling are known for handling plastic waste, they have their own limitations like generation of secondary pollutants and the low quality of the recycled plastic. In this scenario, new methods and technologies for efficiently handling plastic waste are the need of the hour as it is aggravating the concern of pollution and its health risks. This highlight article predominantly focuses on the recently reported combinatorial approach (Angew. Chem. Int. Ed. 2022, 61, e202212013), where it has been shown that integrating the magnetic property of bare Fe3O4 nanoparticles and nanozyme technology can be used for microplastic removal and degradation with nearly 100 % efficiency.

“…The application of hydrophobic materials is limited due to various problems, such as a complex production process, harsh preparation conditions, and poor flexibility. Hence, to improve the comprehensive performance of hydrophobic materials, the development of safe and environmentally friendly materials, such as high‐performance and low‐cost polyurethane acrylate (PUA), 19,20 has gained significant attention. Polyurethane (PU) has excellent low‐temperature performance, wear resistance, and corrosion resistance.…”

Hydrophobic materials possess exceptional properties, making them extensively useful in daily production and life. However, developing low-cost and flexible hydrophobic materials remains a challenging task. In this study, a series of composite emulsions were prepared by introducing hydroxylterminated polydimethylsiloxane as a modifier into polyurethane acrylate via a solvent-free approach. The composite emulsions were then used to fabricate polymer films using the solvent evaporation technique. The effects of varying siloxane content on the properties of composite emulsions and polymer membranes were examined. The results showed that increasing the siloxane content improved the hydrophobic properties and flexibility of the film materials. Fourier transform infrared spectroscopy confirmed the introduction of the Si O Si group into the polyurethane chain structure, the absorption peak for asymmetric stretching vibration of Si O Si is at 1100 cm À1 . The mechanical properties test revealed that the film had excellent elongation at break (278.96 ± 0.01%), and a hydrophobic surface with a contact angle of 101.94 was obtained. The composite materials showed improved water resistance and thermal stability with the increase in siloxane content. The hydrophobic film is a promising material for application in decoration, architecture, and flexible wearable devices.

A noncovalent integration of nanosheets of molybdenum disulfide (MoS2) and the zinc porphyrin complex Zn(II) 5,10,15,20-tetrakis(4-carboxyphenyl)porphine (ZnTCPP) through coordination bonding with metal clusters of zinc acetate (Zn[OAc]2) was applied for synthesis of stable hybrid nanomaterial avoiding surface prefunctionalization. The X-ray powder diffraction in combination with the BET nitrogen adsorption method confirms formation of a ZnTCPP-based surface-attached metal–organic framework (SURMOF) with micropores of 1.63 nm on the MoS2 nanosheets. Fluorescence spectroscopy confirmed Forster resonance energy transfer (FRET) between MoS2 and ZnTCPP without contact quenching. Fluorescent trapping with terephthalic acid for hydroxyl radicals and Sensor Green for singlet oxygen was applied for studying the pathways of photodegradation of model organic pollutant 1,5-dihydroxynaphthalene (DHN) in the presence of SURMOF/MoS2. Visible light initiates sensitization through the excitation of ZnTCPP generating singlet oxygen, whereas UV-light promotes either aerobic FRET-mediated “Z scheme” or anaerobic “Type II heterojunction” mechanisms. Owing to its multimodal photochemistry, the SURMOF/MoS2 hybrid showed comparatively high photocatalytic activity in UV-assisted degradation of DHN (k eff UV = 4.0 × 10–2 min–1) as well as the antibacterial activity confirmed by E. coli survival test under visible light. Noncovalent self-assembly utilizing coordination bonding in SURMOFs as supramolecular adhesive to avoid surface premodification provides a basis for new types of multicomponent nanosystems with switchable functionalities by combining different 2D materials and chromophores in one hybrid structure.
