Special Issue Information

Dear Colleagues,

Novel trending smart carbon-based nanomaterials, carbon dots (CDs), carbon-based 0-dimensional fluorescent materials, and graphene-based hybrid composites with a cost-effective fabrication mechanism, as well as a wide range of raw materials with excellent physical, chemical, optical, and electrical properties, have attracted the attention of many researchers in recent years because of their stable and adjustable photoluminescence behaviors, good biocompatibility, and abundant surface defects. Hybrid carbon-based nanocomposites with suitable physical properties can expand the application scope of CDs, make up for the limitations of single-component CDs in applications, improve the application performance of inorganic nanomaterials, and enhance the versatility of inorganic nanomaterials. These novel composites have been widely utilized in bioimaging, biosensing, catalysis, biology, and optoelectronics.

In this Special Issue, we will focus on brand-new assessment techniques to elucidate the unique functions of CDs in composition regulation, structural fabrication, surface modification, and host–guest interactions in electrocatalysis and ultimately to establish the relationships among structure, composition, and activity. Indeed, the volume will focus on common themes and multidisciplinary expertise in physics, chemistry, biology, materials science, biotechnology, and chemical nanoengineering.

In this study, low-temperature synthesis of a Nb2SnC non-MAX phase was carried out via solid-state reaction, and a novel approach was introduced to synthesize 2D Nb2CTx MXenes through selective etching of Sn from Nb2SnC using mild phosphoric acid. Our work provides valuable insights into the field of 2D MXenes and their potential for energy storage applications. Various techniques, including XRD, SEM, TEM, EDS, and XPS, were used to characterize the samples and determine their crystal structures and chemical compositions. SEM images revealed a two-dimensional layered structure of Nb2CTx, which is consistent with the expected morphology of MXenes. The synthesized Nb2CTx showed a high specific capacitance of 502.97 Fg−1 at 1 Ag−1, demonstrating its potential for high-performance energy storage applications. The approach used in this study is low-cost and could lead to the development of new energy storage materials. Our study contributes to the field by introducing a unique method to synthesize 2D Nb2CTx MXenes and highlights its potential for practical applications. Full article
