Special Issue Information

Dear Colleagues,

Two-dimensional (2D) materials, such as graphene, transition metal dichalcogenides (TMDs), black phosphorus, and MXenes, are materials with thicknesses of only a few atoms, resulting in unique properties that differ from their bulk counterparts. Two-dimensional materials are a promising class of materials for catalysis due to their unique electronic, optical, and mechanical properties. Two-dimensional materials have high surface area, good electrical conductivity, and tunable band gaps, making them effective catalysts for electrocatalysis and photocatalysis. In electrocatalysis, 2D materials such as graphene, TMDs, and MXenes have been shown to be effective catalysts for reactions such as the oxygen reduction reaction and hydrogen evolution reaction. This is because of their high surface area and good electrical conductivity, which allows for efficient charge transfer during catalytic reactions. In photocatalysis, 2D materials such as black phosphorus and TMDs have been studied for applications including water splitting and CO2 reduction. These materials have tunable band gaps that can be adjusted to absorb light and generate electron-hole pairs, which drive catalytic reactions. Overall, the high surface area, good electrical conductivity, and tunable band gaps of 2D materials make them promising candidates for electrocatalysis and photocatalysis. Ongoing research aims to optimize their properties and performance for specific reactions and applications, and to reveal their unique catalytic reaction mechanism.

Transition metal selenides have garnered considerable attention in the field of electrocatalytic oxygen evolution reaction (OER). However, their OER performances still lag behind those of Ir-based materials due to limited exposed active sites, inefficient electron transfer and inadequate stability. In this study, we have successfully synthesized nitrogen-doped NiSe2 nanosheets, which exhibit high efficiency and long-term stability for the OER, requiring only 320 mV to reach a current density of 10 mA cm−2. The nitrogen doping plays a crucial role in effectively regulating the work function and semiconductor characteristics of NiSe2, which facilitates the electron transport and optimizes the catalytic sites. Furthermore, the NiSe2 nanosheets present a larger surface area with more exposed active sites, thus resulting in exceptional OER catalytic activity. The nitrogen-doped NiSe2 nanosheets also display superior stability, maintaining a sustained current density throughout an 8-h OER operation. Full article

Water splitting is considered a renewable and eco−friendly technique for future clean energy requirements to realize green hydrogen production, which is, to a large extent, hindered by the oxygen evolution reaction (OER) process. In recent years, two−dimensional (2D) carbon−based electrocatalysts have drawn sustained attention owing to their good electrical conductivity, unique physicochemical properties, and excellent electrocatalytic performance. Particularly, it is easy for 2D carbon−based materials to form nanocomposites, which further provides an effective strategy for electrocatalytic applications. In this review, we discuss recent advances in synthetic methods, structure−property relationships, and a basic understanding of electrocatalytic mechanisms of 2D carbon−based electrocatalysts for water oxidation. In detail, precious, non−precious metal−doped, and non−metallic 2D carbon−based electrocatalysts, as well as 2D carbon−based confined electrocatalysts, are introduced to conduct OER. Finally, current challenges, opportunities, and perspectives for further research directions of 2D carbon−based nanomaterials are outlined. This review can provide significant comprehension of high−performance 2D carbon−based electrocatalysts for water-splitting applications. Full article
