“…It was shown that the addition of polysaccharide nanofillers subjected to chemical modification with ionic liquids caused a marked increase in the content of the polymorphic β-PP variety, which is reflected in the dispersionmorphological parameters of the analyzed nanofillers. In addition, the increase in the content of the pseudohexagonal variety in the polymer composites is responsible for growing the value of elongation at break, as well as improving impact resistance [80,81].…”

The manuscript discusses the application of dimeric imidazolium ionic liquids with an aliphatic linker of different lengths, constituting a new class of compounds called gemini, for the modification of renewable materials. This innovative functionalization with the use of ionic liquids made it possible to obtain polymer composite nanomaterials with renewable fillers, which will reduce the consumption of petroleum-based raw materials and also be directly related to the reduction of energy intensity. Renewable filler in the form of nanocellulose modified with ionic liquids, as well as polymer composites with such filler obtained by extrusion and injection molding techniques, were subjected to detailed characterization using techniques like: X-ray diffraction (XRD), Fourier transform spectroscopy (FTIR), dispersion studies (DLS), morphological analysis (SEM), differential scanning calorimetry (DSC), hot-stage polarized light microscopy and characterization of mechanical properties. The use of innovative dimeric ionic liquids proved to be an effective method to carry out efficient functionalization of cellulose. This provided a stable space structure between polysaccharide particles, limiting aggregate formation. It was shown that chemical modification with ionic liquids has a significant effect on the nucleation activity of cellulose fillers and the formation of the supermolecular structure of the polymer matrix, which consequently allowed to obtain polymer composites with excellent strength characteristics and increased flexibility, which will allow to increase their application potential. Innovative ionic liquids have contributed to obtaining green nanomaterials with excellent functional properties, which have not been described in the literature so far.

N,S‐Doped highly ordered mesoporous carbon (N,S‐doped OMC) material was constructed by the nanocasting methodology using egg yolk with a high content of amino acids as a carbon precursor and SBA‐15 as a hard template, followed by carbonization at 500 °C under an N2 atmosphere, and then aqueous alkaline‐induced removal of the silica moiety of the SBA‐15 template. Prepared N,S‐doped OMC material efficiently catalyzed the formylation of various substituted anilines using DMF as a formylating agent in water, to afford N‐formylaniline derivatives in high to excellent yields. Also, as‐prepared N,S‐doped OMC was used to immobilize and stabilize the Pd nanoparticles in order to synthesize Pd@OMC material, which was used as an efficient catalyst for the hydrogenation of nitroaromatic compounds to the corresponding aniline derivatives. Nitroaromatic compounds are considered to be highly toxic water contaminant compounds, and their removal from wastewater by the hydrogenation is an interesting method. Furthermore, Pd@OMC catalyzed one‐pot tandem hydrogenation of nitrobenzene/formylation reactions was investigated, which gave corresponding N‐formyl aniline in high yield. Synthesized OMC and Pd@OMC were characterized using X‐ray diffraction (XRD), Brunauer‐Emmett‐Teller (BET), scanning electron microscopy (SEM), energy‐dispersive X‐ray spectroscopy (EDS), and transmission electron microscopy (TEM) analysis.
