Special Issue Information

Dear Colleagues,

Since the discovery of graphene, two-dimensional (2D) materials have become the focus of nanoscience and materials science. The large surface-to-volume ratio, tunable surface properties, and outstanding physical and chemical properties of 2D materials have triggered intensive investigations. The synthesis of high-quality and large-scale 2D materials, as well as the exploration of their applications, including nanoelectronics, catalysts, sensors, bio-applications, and energy conversion and storage, will advance scientific research and facilitate commercial development. In this issue, we focus on the synthesis and applications of existing and newly predicted 2D materials. The topics of interest include, but are not limited to, the following:

  • Synthesis of high-quality and large-scale 2D materials by physical and chemical approaches;
  • Synthesis and prediction of novel 2D materials, including van der Waals and moiré heterostructures;
  • Fundamental understanding and modulation of surface and chemical properties;
  • Synthesis and basic properties of 2D-material-based heterostructures and other architectures;
  • Applications including high-performance nanoelectronics, catalysts, photocatalysts, photovoltaics, batteries, supercapacitors, sensors, bio-applications, etc.

As will be seen in this Special Issue, 2D materials exhibit a wide range of new and unusual properties that can be employed to fabricate improved and novel electronic and electro-optical devices. We look forward to receiving your contributions.

Developing highly active and durable Pt-based electrocatalysts is crucial for polymer electrolyte membrane fuel cells. This study focuses on the performance of oxygen reduction reaction (ORR) electrocatalysts composed of Pt-Pd alloy nanoparticles on graphene nanoplates (GNPs) anchored with sulfated zirconia nanoparticles. The results of field emission scanning electron microscopy and transmission electron microscopy showed that Pt-Pd and S-ZrO2 are well dispersed on the surface of the GNPs. X-ray diffraction revealed that the S-ZrO2 and Pt-Pd alloy coexist in the Pt-Pd/S-ZrO2-GNP nanocomposites without affecting the crystalline lattice of Pt and the graphitic structure of the GNPs. To evaluate the electrochemical activity and reaction kinetics for ORR, we performed cyclic voltammetry, rotating disc electrode, and EIS experiments in acidic solutions at room temperature. The findings showed that Pt-Pd/S-ZrO2-GNPs exhibited a better ORR performance than the Pt-Pd catalyst on the unsulfated ZrO2-GNP support and with Pt on S-ZrO2-GNPs and commercial Pt/C. Full article
