“…In addition, the large broad band of the hydroxyl group at 3298 cm −1 slightly shifted to the right (3288 cm −1 ), and the intensity of the absorption peak was enhanced, which indicates improved intermolecular hydrogen bonding. This result was due to GO, CMC, and PVA all having oxygen‐containing functional groups, which allowed hydrogen bond formation between them 40–42 . The good interaction between GO, CMC, and PVA improved the tensile strength 43…”

In this paper, a graphene‐oxide/carboxymethyl‐chitosan/polyvinyl‐alcohol (GO/CMC/PVA) composite nanofiber membrane was prepared by electrospinning and cross‐linking with glutaraldehyde (GA) to improve the water resistance. The composite nanofiber membrane can be used in the field of heavy metal adsorption. The membrane was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and X‐ray diffraction. The effects of GO concentration, adsorption time, and initial concentration of heavy‐metal ion (Ni2+, Cu2+, Ag+, and Pb2+) solution on the adsorption performance of the fiber membranes were investigated. The results showed that the addition of GO can reduce the diameter of nanofibers. GO, CMC, and PVA exhibited good compatibility, and the intermolecular hydrogen bonding improved. The addition of GO also improved the crystalline properties of the composite fiber membrane. In the optimal cross‐linking condition, GA was saturated by steam cross‐linking for 6 h. The introduction of GO improved the adsorption capacity of the membrane for heavy metals in water. The utmost adsorption capacities for Ni2+, Cu2+, Ag+, and Pb2+ were 262.1, 237.9, 319.3, and 413.6 mg/g when using the cross‐linked composite fiber membranes, respectively. The results of adsorption kinetics and thermodynamics showed that the adsorption process accorded with the pseudo‐second‐order kinetic model and Langmuir–Freundlich isotherm model.

“…Antibiotics are deposited on the surface of GO by π-π interactions and cation-π bonds. The citric acid-modified GO-CMC membrane can be reused and maintains stable recyclability after 5 times of recycling, which can remove antibiotics in wastewater [ 173 ]. For promoting the degradation of OTC in water, a graphene–TiO 2 –Fe 3 O 4 nanocomposite plasma has a good degradation effect.…”

The global energy shortage and environmental degradation are two major issues of concern in today’s society. The production of renewable energy and the treatment of pollutants are currently the mainstream research directions in the field of photocatalysis. In addition, over the last decade or so, graphene (GR) has been widely used in photocatalysis due to its unique physical and chemical properties, such as its large light-absorption range, high adsorption capacity, large specific surface area, and excellent electronic conductivity. Here, we first introduce the unique properties of graphene, such as its high specific surface area, chemical stability, etc. Then, the basic principles of photocatalytic hydrolysis, pollutant degradation, and the photocatalytic reduction of CO2 are summarized. We then give an overview of the optimization strategies for graphene-based photocatalysis and the latest advances in its application. Finally, we present challenges and perspectives for graphene-based applications in this field in light of recent developments.
