Special Issue Information

Dear Colleagues,

In addition to graphene, a new family of 2D nanomaterials, MXenes, which include metal carbides, carbonitrides, and nitrides (for instance Ti3C2, Mo3C, Nb2C, and others), have attracted great attention recently due to their unique 2D structure, good conductivity, excellent mechanical properties, and satisfying hydrophilicity. More and more studies on the synthesis and applications of 2D MXenes have been performed, in which the modification and functionalization of MXenes plays a crucial role for the synthesis of MXene-based functional nanomaterials. For example, the chemical modification and functionalization of MXenes have made it possible to conjugate MXenes with other functional building blocks to form hybrid nanomaterials with multifunctions; the functionalization of MXenes and subsequent hybridization with graphene, carbon nanotubes, and metal nanoparticles have extended their applications in the nanotechnology, energy, and environmental fields; and the bio-functionalization of MXenes with biopolymers, DNA, protein, peptides, enzymes, and others have improved their potentials for biosensors, tissue engineering, drug delivery, bioimaging, and cancer therapy applications.

To present recent advances in this emerging field, we here propose a Special Issue focused on the synthesis, functionalization, hybridization, and applications of MXene-based nanomaterials. We would like to invite researchers to contribute to this project and welcome the studies involved in but not limited to these topics:

  • Synthesis and functionalization of MXenes;
  • Bio-functionalization methods of MXenes;
  • Hybrid nanomaterials based on MXenes;
  • MXene-based nanomaterials for energy storage applications;
  • MXene-based nanomaterials for environmental applications;
  • MXene-based nanomaterials for biomedical applications.

Two-dimensional (2D) nanomaterials have attracted increased interest and exhibited extended applications from nanotechnology to materials science, biomedicine, tissue engineering, as well as energy storage and environmental science. With the development of the synthesis and fabrication of 2D materials, a new family of 2D materials, metal carbides (MCs), revealed promising applications in recent years, and have been utilized for the fabrication of various functional 2D and three-dimensional (3D) nanomaterials for energy and environmental applications, ascribing to the unique physical and chemical properties of MCs. In this review, we present recent advance in the synthesis, fabrication, and applications of 2D and 3D MC-based nanomaterials. For this aim, we first summarize typical synthesis methods of MCs, and then demonstrate the progress on the fabrication of 2D and 3D MC-based nanomaterials. To the end, the applications of MC-based 2D and 3D materials for chemical batteries, supercapacitors, water splitting, photodegradation, removal of heavy metals, and electromagnetic shielding are introduced and discussed. This work provides useful information on the preparation, hybridization, structural tailoring, and applications of MC-based materials, and is expected to inspire the design and fabrication of novel and functional MXene materials with improved performance.

With increasing research interest in the field of flexible electronics and wearable devices, intensive efforts have been paid to the development of novel inorganic-organic hybrid materials. As a newly developed two-dimensional (2D) material family, MXenes present many advantages compared with other 2D analogs, especially the variable surface terminal groups, thus the infinite possibility for the regulation of surface physicochemical properties. However, there is still less attention paid to the interfacial compatibility of the MXene-organic hybrids. To this end, this review will briefly summarize the recent progress on MXene-organic hybrids, offers a deeper understanding of the interaction and collaborative mechanism between the MXenes and organic component. After the discussion of the structure and surface characters of MXenes, strategies towards MXene-organic hybrids are introduced based on the interfacial interactions. Based on different application scenarios, the advantages of MXene-organic hybrids in constructing flexible devices are then discussed. The challenges and outlook on MXene-organic hybrids are also presented. Full article
