Special Issue Information

Dear Colleagues,

The development of energy conversion and storage methods has attracted a great deal of attention to counter the global energy crisis and environmental issues. Materials science plays a vital part in energy conversion and storage technologies; consequently, a search for novel and efficient materials is the need of the hour. Particularly, two-dimensional (2D) materials have taken centre stage in research, owing to their unique structural, electronic, mechanical, and surface properties which have led to their potential applications in energy conversion and storage.

The goal of this Special Issue is to share the recent progress in the applications of low-dimensional materials in energy conversion and storage. Topics of interest broadly include theoretical and/or experimental research on 2D materials’ properties and applications, including:

  • Materials for water splitting;
  • Materials for CO2 reduction;
  • Thermoelectric materials;
  • Materials for photovoltaics;
  • Materials for fuel cells;
  • Electrode materials for metal ion batteries;
  • Piezoelectric materials.

Searching for efficient electrode materials with excellent electrochemical performance is of great significance to the development of magnesium-ion batteries (MIBs). Two-dimensional Ti-based materials are appealing for use in MIBs due to their high cycling capability. On the basis of density functional theory (DFT) calculations, we comprehensively investigate a novel two-dimensional Ti-based material, namely, TiClO monolayer, as a promising anode for MIBs. Monolayer TiClO can be exfoliated from its experimentally known bulk crystal with a moderate cleavage energy of 1.13 J/m2. It exhibits intrinsically metallic properties with good energetical, dynamical, mechanical, and thermal stabilities. Remarkably, TiClO monolayer possesses an ultra-high storage capacity (1079 mA h g−1), a low energy barrier (0.41–0.68 eV), and a suitable average open-circuit voltage (0.96 V). The lattice expansion for the TiClO monolayer is slight (<4.3%) during the Mg-ion intercalation. Moreover, bilayer and trilayer TiClO can considerably enhance the Mg binding strength and maintain the quasi-one-dimensional diffusion feature compared with monolayer TiClO. All these properties indicate that TiClO monolayers can be utilized as high-performance anodes for MIBs. Full article
