The carbonization of collagen-based leather waste to nitrogen-containing carbon is reviewed with respect to the preparation, characterization of carbonized products, and applications proposed in the literature. The resulting nitrogen-containing carbons with fibrous morphology have been used as adsorbents in water pollution treatment, in electrocatalysis, and especially in electrodes of energy-storage devices, such as supercapacitors and batteries. Although electrical conductivity has been implicitly exploited in many cases, the quantitative determination of this parameter has been addressed in the literature only marginally. In this report, attention has been newly paid to the determination of conductivity and its dependence on carbonization temperature. The resulting powders cannot be compressed into pellets for routine conductivity determination. A new method has been used to follow the resistivity of powders as a function of pressure up to 10 MPa. The conductivity at this pressure increased from 9.4 × 10−8 S cm−1 for carbonization at 500 °C to 5.3 S cm−1 at 1000 °C. The conductivity of the last sample was comparable with conducting polymers such as polypyrrole. The carbonized leather thus has the potential to be used in applications requiring electrical conduction.

“…(Kyzas et al., 2014). Moreover, properties like specific surface activity, porous structure, and high chemical and thermal stability are also vital for higher adsorption (Masindi et al., 2022; Gupta et al., 2022; Bharathi et al., 2022). Recently, various types of nanomaterials have been used as absorbents for the removal of several contaminants from wastewater in adsorption processes.…”

Increasing demand for pure, safe, and affordable water is one of the biggest challenges worldwide. Various pollutants such as dyes, heavy metals, bacteria, pesticides, and pharmaceuticals are present in water and their removal is the major challenge for us. In this respect, various materials have been developed to remove the various types of pollutants from wastewater. Recently, 3D graphene‐based materials (3D GBMs) have received a great deal of attention in wastewater treatment due to their extraordinary properties. The large surface area, porous structure, versatile surface chemistry with exceptional physiochemical properties such as mechanical and electrical properties, and excellent thermal and chemical stability make them excellent absorbent candidates for wastewater treatment. The materials properties of 3D graphene‐based materials (3D GBMs) and their environmental performance as well as the key parameters that influence their capacities for removal of pollutants from the wastewater have also been discussed. The aim of this review is to provide the recent progress in removing several water pollutants like dye, oil, organic solvents, heavy metal ions, bacteria, and pathogens from wastewater. Furthermore, this review also contains the future development opportunities and technical challenges of 3‐D graphene‐based materials in wastewater treatment.

Co2Fe2O4 NPs were made using the sol‐gel ignition technique employing citric acid (C6H8O7.6H2O) as a reducing agent to oxidizing agent with a ratio of 1 : 3. A thorough study of the effects of divalent Zn2+ and trivalent Y3+ ion on their structural, Infra‐red, morphological, magnetic, DC‐electrical, optical, and photocatalytic activity. All of the samples have crystallized to a cubic spinel structure with a single phase space group Fd3m, according to the analysis of the XRD pattern consisting of the intense reflections (220), (311) (222), (400), (422), (511), (440), (533), and (444). Transmission electron microscopy (TEM) suggested the particle size range of ~27 nm; and demonstrates the agglomerations on the tip of MNPs, which are ideal for increasing surface area, and infrared study verifies the spinel structure. With a decrease in the hysteresis loop for the Zn−Y ligand, the magnetic hysteresis loops demonstrate a ferrimagnetic character. With Zn−Y, magnetic characteristics are noticeably affected; saturation magnetization (Ms) 70.9133 to 59.2148 emu/g; and coercivity (Hc) 1900.30 to 193.96 Oe both exhibit a decrease. The DC‐electrical resistivity image reveals the CFMNPs′ semiconducting nature and the optical energy bandgap demonstrates a decrease from their original state. The MB dye's decolorization demonstrates the amazing deterioration in a short amount of time 20 to 80 minutes range was observed to be 35.88, 61.92, 76.40, and 94.07 %.
