Special Issue Information

Dear Colleagues,

This Special Issue aims to highlight recent advances in the synthesis, functionalization, and application of graphene and graphene-related materials in the fields of energy and environmental sustainability.

Innovative approaches that harness the unique properties of graphene-related materials for alternative energy solutions will be mainly considered, including their use in fuel cells, accumulators, and capacitors. These materials offer exceptional conductive properties, a highly tunable surface area, and mechanical strength, making them ideal for enhancing the performance and durability of energy storage and conversion systems.

In addition to energy applications, this Special Issue welcomes contributions addressing the role of graphene-based materials in environmental remediation, particularly for advanced wastewater treatment techniques such as adsorption, photocatalysis, and membrane-based separation.

Moreover, the Special Issue will cover emerging uses of graphene-based components in industrial catalysis, where their tunable surface chemistry and structural versatility enable efficient and selective catalytic processes. We invite original research articles and reviews that explore the synthesis routes, structural optimization, and application-oriented design of graphene-based materials addressing current challenges in energy and environmental technologies.

The presence of secondary electromagnetic waves (EMWs) results in EMW pollution and a large need for EMW-shielding materials. Therefore, new, lightweight, flexible, chemically resistant, and durable EMW shielding materials are demanded, while graphene and its derivatives meet the above-mentioned requirements. Among graphene derivatives, N-doped graphene exhibits promising electrical properties for shielding applications, although achieving sufficient N-incorporation in the graphene sheets remains a challenge. Herein, we produced graphene oxide using the modified Hummers’ method (GO) and the electrochemical exfoliation of highly ordered pyrolytic graphite. These two GO samples were thermally treated at 500 °C and 800 °C under a pure NH3 gas for 1 h. UV-Vis, infrared, and Raman spectroscopies and X-ray diffraction, elemental, and thermogravimetric analyses were used to investigate the structural properties of modified GO. One of the highest levels of N-doping of GO was measured (11.25 ± 0.08 at%). The modification under a NH3 atmosphere leads to simultaneous N-doping and reduction of graphene, resulting in the formation of electrically conductive and EMW shielding materials. Density functional theory (DFT) revealed the effect of heteroatoms on the energy band gap of GO. The cluster corresponding to N-doped rGO had a reduced bandgap of 0.77 eV. Full article
