Special Issue Information

Dear Colleagues,

Graphene is a 2D carbon material with amazing chemical, electrical and mechanical properties. A great deal of research has been devoted to modifying graphene to enable its use in several applications. Recent progress in graphene derivatives, such as graphitic carbon nitride, graphene oxide, reduced graphene oxide, and others, demonstrated the potential of this material. In particular, reduced graphene oxide (rGO) sheets show remarkable unique electronic and structural properties. Due to its excellent electric charge carrier mobility, thermal conductivity, mechanical strength and flexibility, large specific surface area and capacity for surface functionalization, rGO has been universally accepted to serve as an ideal charge carrier shuttle and catalysis support.

The aim of the Special Issue is to reveal the mysterious role of graphene and its derivatives in energy and environmental catalysis, helping to achieve the goals of reaching carbon peak and carbon neutralization. We welcome papers dealing with graphene oxide, reduced graphene oxide, graphitic carbon nitride and other graphene derivatives for catalytic applications. We are looking forward to receiving your valuable research results, and are grateful for your support and contributions. Your active participation and input will be the basis of a successful outcome. We look forward to your submissions.

Hierarchically porous carbon (PC) was synthesized by a templating method, using magnesium salts (Mg(HCO3)2, MgC2O4 and MgO) as template precursors and citric acid as carbon precursor. During the carbonization process, besides the production of MgO particles, many gases (e.g., CO2/NO2/H2O) were also released and acted as a porogen to generate pores in carbon. The resulting composite (MgO@C) was subsequently treated with HCl solution to remove the MgO templates, yielding hierarchically porous carbon. The surface oxygen functional groups over porous carbon were characterized by TPD and XPS, which showed that the PC-bic, synthesized using Mg(HCO3)2 as the template precursor, had the highest value among the PCs. As expected, the PC-bic exhibited the best performances for electrocatalytic reduction of 4-nitrophenol, with a peak current of −135.5 μA at −0.679 V. The effects of 4-nitrophenol concentration, buffer solution pH and scanning rate on the electrocatalytic activities, as well as the stability of PC-bic for the reaction were investigated.
