Iron and nitrogen-doped carbon substances with abundant active sites that related to dispersion of heteroatom species (Fe and N) on the surface of carbonous structure, are promising choice for eco-friendly catalytic reactions. Herein, cellulose-based ionic liquid (IL) derivative not only employed as the both nitrogen and iron heteroatom precursors, but also has been used as the green and biodegradable substrate. The non-noble Fe-NC@550, was successfully fabricated by convenient carbonization of cellulose-based IL. Further, the FeCl anion was used as the iron precursor and also it has been applied to elevate the SSA (specific surface area) of catalyst (from 40.96 to 160.42 m/g) due to the presence of chlorine. On the basis of several pertinent physicochemical and experimental outcomes, the structure of the catalyst was successfully proved in different synthetic steps. As expected, the Fe-NC@550 exhibited the substantial efficiency toward hydrogenation of nitroarenes with high TOF value and also remarkable reusability.

The widespread use of traditional petroleum-based plastics has created an environmental crisis and health hazard, so there is an urgent need for bioplastics with excellent performance. However, fabricating of robust mechanical properties and heat resistance bioplastics in an efficient way has remained an enormous challenge. Herein, we proposed a strategy for the synergistic preparation of high-performance bioplastics with multiple physical crosslinking network structures via noncovalent and coordination bonds.

Gel polymer electrolytes (GPEs) are regarded as a promising alternative to conventional electrolytes, combining the advantages of solid and liquid electrolytes. Leveraging the abundance and eco-friendliness of cellulose-based materials, GPEs were produced using methyl cellulose and incorporating various doping agents, either an ionic liquid (1-Butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide [Pyr14][TFSI]), its polymeric ionic liquid analogue (Poly(diallyldimethylammonium bis(trifluoromethylsulfonyl)imide) [PDADMA][TFSI]), or an anionically charged backbone polymeric ionic liquid (lithium poly[(4-styrenesulfonyl)(trifluoromethyl(S-trifluoromethylsulfonylimino) sulfonyl) imide] LiP[STFSI]). The ion dynamics and molecular interactions within the GPEs were thoroughly analyzed using Attenuated Total Reflectance Fourier-Transform Infrared Spectroscopy (ATR-FTIR), Heteronuclear Overhauser Enhancement Spectroscopy (HOESY), and Pulsed-Field Gradient Nuclear Magnetic Resonance Diffusion (PFG-NMR).

Transient technology involves materials and devices that undergo controlled degradation after a reliable operation period. This groundbreaking strategy offers significant advantages over conventional devices based on non-renewable materials by limiting environmental exposure to potentially hazardous components after disposal, and by increasing material circularity. As the most abundant naturally occurring polymer on Earth, cellulose is an attractive material for this purpose.
