Metal–organic frameworks (MOFs) as porous materials have recently attracted research works in removal of toxic pollutants from water. Cr(VI) is well-known as one of the most toxic forms of chromium and the selection of efficient and effective Cr(VI)-remediation technology must be focused on a number of important parameters. Therefore, the objective of this work is to fabricate a novel nanohybrid adsorbent for removal of Cr(VI) by using assembled bimetallic MOFs (Fe0.75Cu0.25-BDC)-bound- Alginate-MoO3/Graphene oxide (Alg-MoO3/GO) via simple solvothermal process. The aimed Fe0.75Cu0.25-BDC@Alg-MoO3/GO nanohybrid was confirmed by FTIR, SEM, TEM, XRD and TGA. Adsorptive extraction of Cr(VI) from aqueous solution was aimed by various optimized experimental parameters providing optimum pH = 3, dosage = 5–10 mg, starting concentration of Cr(VI) = 5–15 mg L−1, shaking time = 5–10 min. The point of zero charge (pHPzc) was 3.8. For Cr(VI) removal by Fe0.75Cu0.25-BDC@Alg-MoO3/GO, four isotherm models were estimated: Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D-R) with calculated correlation coefficient (R2 = 0.9934) for Langmuir model which was higher than others. The collected results from the kinetic study clarified that pseudo-second order model is the most convenient one for describing the adsorption behavior of Cr(VI) and therefore, the adsorption process was suggested to rely on a chemisorption mechanism. Thermodynamic parameters referred that the adsorption mechanism is based on a spontaneous and exothermic process. Finally, the emerged Fe0.75Cu0.25-BDC@Alg-MoO3/GO nanohybrid was confirmed as an effective adsorbent for extraction of hexavalent chromium from real water specimens (tap, sea water and wastewater) with percentage recovery values > 98%.

“…This creates a pressing need for recycling spent batteries that are released into the environment, with zinc–carbon batteries accounting for a large percentage of this trash each year, which has major negative effects on soil and water contamination. Many of these methods have been studied in industry with initial success, such as pyrolysis, , pyrometallurgically treatment, chemical activation, , chemical route, dried calcination, , and electrochemical exfoliation. − One of the highlights here is that the carbon rod in zinc–carbon batteries can be reused to synthesize the two-dimensional material graphene, one of the first two-dimensional materials to change modern technology.…”

The recycling of spent batteries has always been a daunting and difficult task throughout the long history of battery development. Zinc−carbon batteries, one of history's most popular batteries, still widely used today, have become a serious environmental problem. Although zinc−carbon batteries are the first primary batteries that belong to non-rechargeable cells, they are still widely used as a result of their low cost and ease of product. Currently, thousands of tons of zinc−carbon batteries are released into the environment each year, requiring advanced recycling methods. Among various strategies that have been developed, electrochemistry is one of the interesting methods, with the advantages of being cheap and fast and able to synthesize a new material, graphene, a material that changes the technology game. Graphene derived from carbon rods in spent zinc−carbon batteries has been successfully synthesized by a short-time, simple instrumentation of electrochemical exfoliation under direct current supply, which demonstrates a low-cost and environmental strategy for mass production of graphene material from electronic device waste. This review provides a great overview aiming to introduce the electrochemical exfoliation method to recycle spent zinc−carbon batteries to synthesize graphene materials, which contributes to battery recycling technology as an alternative strategy.

The research objective of this work is to reuse graphite rods recovered from used batteries and utilize them as an additive in SAE20W40 oil to improve the engine parts’ lubrication ability and wear resistance. The graphite rods are grated to obtain ultra-fine particles and then chemically exfoliated using an Improved Hummer's process that results in graphene oxide. Then, it is thermally reduced at 350 °C to yield reduced graphene oxide. Different ratios (0.25, 0.50, 0.75, and 1.00 wt.%) of as-grated graphite particles and reduced graphene oxide were dispersed in the above oil to form a colloidal solution and then used for tribological studies. The graphite particles and synthesized reduced graphene oxide were characterized using X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy. X-ray diffraction data confirms the presence of graphite, graphene oxide, and reduced graphene oxide in the prepared powders and matches with the standard files. High-resolution transmission electron microscopy images reveal the presence of multilayer sheets with an interplanar distance of 0.34 nm having wrinkles, folds, and gas holes. The G and D band positions of Raman spectra prove the formation of oxygenated functional groups, and the ID/ IG ratio confirms the defects in graphene oxide and reduced graphene oxide. The viscosity of prepared lubricant increases by 35% and 21% for graphite and reduced graphene oxide, respectively. The results of tribological studies with 0.25 wt.% graphite and 0.5 wt.% reduced graphene oxide lubricants showed improvement in coefficient of friction by 32% and 36%, respectively. At these optimal concentrations, the specific wear rate dropped by 51% for reduced graphene oxide. Scanning electron microscopy/energy dispersive spectroscopy, images show that the nanolubricant's mending effect over the worn surface improves reduced graphene oxide added SAE20W40 oil tribological characteristics. From the results, reduced graphene oxide synthesized from as-grated graphite rods proves to be a low-cost, sustainable, and effective friction modifier for engine oils.
