Designing low-energy consumption, highly sensitive, and stable room temperature (RT) gas sensors based on green renewable materials is both significant attractive. Cellulose nanocrystals (CNC), eco-friendly extracted from the most abundant natural polymer, cellulose, possess unique characteristics, including one-dimensional nanorod structures, functional groups, large specific surface area, a high aspect ratio, point-to-point conductive network structure. These characteristics have shown great potential in development of high-performance sensors. Herein, magnificent C–Cu2O/CuO nanocomposite facilely synthesized CNC/Cu2+ aerogel freeze-drying method followed by subsequent heat treatment. By adjusting degree annealing, material forms heterogeneous structure that conducive to enhancing its sensing properties. Structural characterization confirms heterostructured Cu2O/CuO hollow nanospheres are formed embedded within CNC-derived carbon, providing active sites for molecule adsorption, thereby ensuring performance. The as-prepared sensor exhibits sensitivity (∼1801 toward 10 ppm), excellent linearity, selectivity NO2 at 25 °C. Intriguingly, calculated limit detection (LOD) sensor, which integrates merits CNC Cu2O/CuO, as low 0.15 ppb. Therefore, it believed proposed idea constructing nanostructures provides universal strategy developing other types carbon-supported porous metal oxide nanocomposites.

Abstract This study demonstrates the effective copolymerization of N‐Vinyl pyrrolidone and methyl methacrylate using reduced graphene oxide adorned with copper nanoparticles (CuO‐rGO) acting as a catalyst when exposed to blue LED irradiation generate random copolymer hybrid system P(NVP‐co‐MMA/CuO‐rGO). We investigated effects this P(NVP‐co‐MMA/CuO‐rGO) on mechanical, thermal antibacterial properties epoxy (DEGBA‐DETDA) composite. By employing two different concentrations CuO nanoparticle, we assessed reinforcement capability synthesized copolymer‐nanoparticle within an matrix. observed that composite sample comprising P(NVP‐co‐MMA/CuO‐rGO), having 0.5% CuO‐rGO (Cu002) respect concentration resulted in significant enhancements fracture toughness. Further mechanical samples were studied DMA, DSC TGA. Microstructural Mechanisms toughening are elucidated through examination SEM images depicting surfaces. Moreover, composites exhibited notable activity against both E. coli S. aureus compared control. These findings highlight system's role multifunctional filler, enhancing composites' durability, functionality, performance. Our work advances field by showcasing customized use nanoparticle‐enhanced copolymers improve material properties, providing valuable insights for development next‐generation materials. Highlights Achieved novel methacrylate. successfully facilitates nanocomposite formation. proved filler epoxy. reinforced enhances toughness 143% over neat Reinforced showed better efficacy & versus
