Special Issue Information

Dear Colleagues,

MXenes, a big family of 2D transition metal carbides, carbonitrides, and nitrides, are rising increasing attention in the fields of energy storage, catalysis, sensors, electronics, environment science, optics, etc. The surge of interest in MXenes can be attributed to several desirable physical and chemical merits, including large and tunable interlayer spaces, extraordinary metallic conductivity, tunable surface chemistries, excellent hydrophilicity, compositional and structural diversity. However, physical and chemical properties are strongly influenced by features of MXene itself and synthetic approaches. For example, for electrochemical energy storage, the different synthetic strategies and properties of MXenes will enable MXenes to play different roles as active materials, conductive additives, artificial protective layer, current collectors, electrolyte additives, etc. Therefore, the fundamental investigations on the synthesis and properties of MXene-based materials are necessary and urgent for boosting the advances of practical applications.

In this Special Issue, we will focus on green and innovative synthetic methods, synthesis and theoretical model prediction of novel MXenes, functionalization design, regulation of physical and chemical properties, advanced characterization, and applications of MXenes-based materials. We would like to invite original research articles and comprehensive reviews providing innovative research work and deep insights into MXene-based materials. Research areas may include (but not limited to) the following:

  • Green synthesis of MXenes
  • Synthesis of novel MXenes
  • Synthesis of novel and promising MXenes-based derivatives
  • Functionalized design of MXenes
  • Regulation of properties of MXenes
  • Advanced characterization of MXenes-based materials
  • MXenes-based materials for rechargeable batteries
  • MXenes-based materials for nanogenerators
  • We look forward to receiving your contributions.

As a potential negative electrode material for lithium-ion batteries (LIBs), silicon has a relatively high specific lithium storage capacity. However, the large volume change during the cycle may result in the isolation with the current collector and therefore the rapid capacity decay during cycling. The poor electric conductivity of the silicon limits the high-power density application in LIBs. To meet the above challenges, a stable Si/Ti3C2Tx composite material was designed. Si nanoparticles are bonded with -NH2 group so that the silicon surface has a positive charge, which can then be electrostatic self-assembly with negatively charged MXene nanosheets in a facile freeze-drying method. Silicon nanoparticles were anchored on the surface or inside the interspace of the MXene nanosheets, which could improve the conductivity of the composites. The composite material (NH2-Si/MXene) presented a stable and porous structure with extra room for silicon expansion and plentiful channels for carrier transportation. Benefiting from the improved structural stability and enhanced charge storage dynamics, the discharge capacity of NH2-Si/MXene is 1203.3 mAh g−1 after 100 cycles at 200 mA g−1. These results provide new insights for the application of silicon-based negative electrode materials in high-energy-density LIBs. Full article
