“…Notably, when FCO was compared to GO, the specific surface area, total pore volume, the average pore width of FGO had a slightly higher BET surface area 34.226 m 2 /g, 0.074 cm 3 /g and 9.016 nm, respectively. Such increase in the BET surface area and porosity upon the amine functionalization of GO might be attributed to the rearrangement of the exfoliated layers . Such a trend has also been reported by other researchers. , Figure e depicts the TEM morphology of GO and FGO, respectively.…”

In this study, graphene oxide (GO) was functionalized with 3,5-diaminobenzoic acid (DABA) by a one-step method to produce functionalized graphene oxide (FGO). FGO is a new type of absorbent crystalline substance that has a high surface area and a large porosity site as well as a large number of dentate functional groups which lead to enhanced adsorption performance for heavy metal ions. The adsorption efficiency of FGO for Pb+2 and Al+3 metal ions was extra satisfactory when compared with GO due to the ease of design and the homogeneous structure of FGO. The structure of synthesized GO and FGO was confirmed by different techniques such as FTIR, XRD, TGA, BET nitrogen adsorption–desorption methods, and TEM analyses. The mass of utilized adsorbents, the pH of the medium, the concentration of ionic species in the medium, temperature, and process time were all investigated as variables in the adsorbent procedure. The experimental data recorded that the maximum adsorption efficiency of the 0.5 g/L FGO composite was 99.7 and 99.8% for Pb+2 and Al+3 metal ions, respectively, while in the case of using GO, the maximum adsorption efficiency was 92.6 and 91.9% at ambient temperature in a semineutral medium at pH 6 after 4 h. The adsorption results were in good conformity with the Freundlich model and pseudo-second-order kinetics for Pb+2 and Al+3 metal ions. Also, the reusability study indicates that FGO can be used repeatedly at least for five cycles with a slight significant loss in its efficiency.

“…45 This type of hysteresis frequently corresponds to materials with slit-shape pores and broad pore size distribution. 46 The GO isotherm demonstrates relatively higher low-pressure gas uptake and more high-pressure N 2 sorption than Ni@A-GO, attributed to the occupation of micro/mesopores as a consequence of amine attachment and Ni induction. The corresponding BET-specific surface areas of GO and Ni@A-GO were calculated at 189 and 164 m 2 g −1 , respectively.…”

Graphene oxide (GO) has been broadly utilized as a starting precursor for electrochemical applications due to its unique tunable characteristics. In this work, a Ni(II)@amine-functionalized graphene oxide composite was introduced as a high-performance supercapacitor electrode theoretically and experimentally. The composite (Ni@A-GO) was fabricated through a facile synthesis route, utilizing nickel stabilized on glutamine. Fourier-transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), Raman, scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDX) were utilized to characterize the synthesized sample. The first-principle study revealed a significantly higher quantum capacitance of Ni@ A-GO than GO. In line with theoretical results, experimental investigation exhibited its high capacitance of 1136 F g −1 at a 2 A g −1 current density with a significant capacitance retention of 84% at 5 A g −1 as well as good stability for 12 000 cycles, in a threeelectrode system. Moreover, an asymmetric two-electrode device

“…Graphene and GO have garnered considerable interest as enzyme support materials among carbon-based substances, thanks to distinctive characteristics such as their biodegradability, two-dimensional structure, extensive surface area, pore volume, and excellent chemical and thermal stability [186,187]. Different chemical groups, like hydroxyl (-OH), carboxylic (COOH), and epoxide groups, can form strong enzyme-matrix interactions without the need for coupling agents or modifying the graphene surface [188].…”

Addressing the critical issue of water pollution, this review article emphasizes the need to remove hazardous dyes and phenolic compounds from wastewater. These pollutants pose severe risks due to their toxic, mutagenic, and carcinogenic properties. The study explores various techniques for the remediation of organic contaminants from wastewater, including an enzymatic approach. A significant challenge in enzymatic wastewater treatment is the loss of enzyme activity and difficulty in recovery post-treatment. To mitigate these issues, this review examines the strategy of immobilizing enzymes on newly developed nanostructured materials like graphene, carbon nanotubes (CNTs), and metal–organic frameworks (MOFs). These materials offer high surface areas, excellent porosity, and ample anchoring sites for effective enzyme immobilization. The review evaluates recent research on enzyme immobilization on these supports and their applications in biocatalytic nanoparticles. It also analyzes the impact of operational factors (e.g., time, pH, and temperature) on dye and phenolic compound removal from wastewater using these enzymes. Despite promising outcomes, this review acknowledges the challenges for large-scale implementation and offers recommendations for future research to tackle these obstacles. This review concludes by suggesting that enzyme immobilization on these emerging materials could present a sustainable, environmentally friendly solution to the escalating water pollution crisis.
