“…The combination of metal oxides, CuO and ZnO in general exhibit enhanced chemical, mechanical, and physical properties along with reduced melting temperature, high diffusion, structural stability, enlarged surface area, and high surface energy [15] . CuO, a p‐type semiconductor, and ZnO, an n‐type semiconductor, both have narrow band gaps of 2.5 eV and broad band gaps of 3.37 eV [16,17] …”

Pure CuO and 2‐Dimentional CuO−ZnO nanocomposites (NCs) were effectively prepared by an ultrasound‐assisted probe sonication route for different ratios of CuO and ZnO, and the multifunctional properties were investigated by the application of the advanced methods. XRD (X‐ray diffraction) patterns revealed a crystallite size (D) range of 25 to 31 nm for pure CuO and CuO−ZnO NCs. According to calculations, the energy band gap value (Eg) for the NCs is between 2.15 and 2.48 eV. Under UV light irradiation, the photocatalytic degradation of pure CuO and CuO−ZnO NCs on Direct Green (DG) and Fast Blue (FB) dyes was assessed. 60 mg of the catalyst was added to 20 ppm solutions of DG and FB dye. The stock solution of the dyes was prepared 10, 15, 20 and 25 ppm of 250 ml dye solution. Electrochemical analysis using cyclic voltammetry revealed improved redox potential output in the electrode crafted with graphite powder in 0.1 N HCl electrolyte solution. These NCs were used because of their capacity to detect an extremely dangerous chemical like arsenic. The constructed electrode‘s lowest limit of detection was determined to be 110–3 mol/L. In general, vertical linearity was seen in all of the prepared nano‐electrodes, especially above 150 ohms with real axis for pure CuO but beyond 100 ohms for doped electrodes. Based on our study, we conclude that the CuO and ZnO NCs, containing 10 % of ZnO, were the most effective photocatalyst for DG and FB dyes and electrochemical sensor for Arsenic.

The latest advancements in cellulose and its derivatives are the subject of this study. We summarize the characteristics, modifications, applications, and properties of cellulose. Here, we discuss new breakthroughs in modified cellulose that allow for enhanced control. In addition to standard approaches, improvements in different techniques employed for cellulose and its derivatives are the subject of this review. The various strategies for synthetic polymers are also discussed. The recent advancements in polymer production allow for more precise control, and make it possible to make functional celluloses with better physical qualities. For sustainability and environmental preservation, the development of cellulose green processing is the most abundant renewable substance in nature. The discovery of cellulose disintegration opens up new possibilities for sustainable techniques. Based on the review of recent scientific literature, we believe that additional chemical units of cellulose solubility should be used. This evaluation will evaluate the sustainability of biomass and processing the greenness for the long term. It appears not only crucial to dissolution, but also to the greenness of any process.

“…In terms of renewability and sustainability, the use of direct or functionalized forms of biomass is important because they are biodegradable instead of synthetic and petroleum-based materials. In addition, ensuring the use of biomass is an important recovery process in terms of reducing environmental concerns and developing new environmentally friendly products and materials (Abdul Khalil et al, 2014;Ahmed et al, 2022;Arun et al, 2022;Wang et al, 2022). Hemp is a great candidate for biomass and biomass-based products nowadays.…”

It has become increasingly popular in recent years to create improved functionalized nanomaterials in an effort to enhance their physicochemical, catalytic, and biological capabilities. In this study, eco-friendly, especially water dispersible bio-nanocomposites containing metal ferrite, MFe2O4 (M: Cu, Ni, Cd, Mn and Co) nanoparticle were synthesized low-cost method from hemp biomass and characterized by ATR-FTIR, XRD, SEM, TEM (STEM), EDX, VSM, Uv-Vis and TG/DTG analyses. The variation of their ionic conductivity with temperature and concentration and also their catalytic effects against cationic dyes such as methylene blue (MB), crystal violet (CrV) and malachite green oxalate (MGO) were investigated. XRD patterns and FTIR spectra of the AHB-MFe2O4, especially the stretching of Fe-O and M-O, showed the formation of metal ferrite bio-nanocomposites. Also, interaction between the biomass and metal ferrite nanoparticles was obviously seen from XRD patterns and FTIR spectra of the AHB-MFe2O4. It was determined that AHB-MFe2O4 bio-nanocomposites have high thermal stability, high ionic conductivity and negative surface charge. Moreover, they exhibited high catalytic performance against cationic dyes such as MB, CrV and MGO.
