Advances in Low-Dimensional Materials (LDMs) for Energy Conversion and Storage

Topic Information

Dear Colleagues,

Low-dimensional materials are generally defined as materials with at least one dimension in the nanometer range. As such, these materials exhibit extremely high surface area to volume ratios, and the reduction in dimensionality leads to quantum confinement effects that engender unique physical properties that are substantially different from their bulk counterparts. Furthermore, their atomically well-defined structures are amenable to rigorous theoretical modeling, which allows for the computationally guided design of materials and devices.

Extraordinary light-matter interactions in low-dimensional materials are particularly appealing for energy conversion devices, including solar cells, light emitting diodes, photoelectrochemical cells, etc., as it provides the ability to tune the spectral range of emission and absorption. Low-dimensional materials are also of great importance in energy storage devices such as lithium ion batteries and electrochemical capacitors because of their exceptional cycling stability and high charge storage capacity.

The present topic aims to provide recent advances as well as future prospects in the field of low-dimensional materials for energy conversion and storage; therefore, we welcome original articles, perspectives, and review articles.

We invite authors to submit their latest experimental and theoretical contributions in areas including but not limited to:

- Synthesis of characterization of low-dimensional materials;
- Advances in analytical tools (in situ, ex situ, operando);
- Applications in energy conversion;
- Applications in energy storage.

The pursuit of efficient cathode catalysts to improve cycle stability at ultra-high rates plays an important role in boosting the practical utilization of Li-O₂ batteries. Featured as industrial solid waste, coal gangue with rich electrochemical active components could be a promising candidate for electrocatalysts. Here, a coal gangue/Ti₃C₂ MXene hybrid with a TiO₂/SiC_x active layer is synthesized and applied as a cathode catalyst in Li-O₂ batteries. The coal gangue/Ti₃C₂ MXene hybrid has a tailored amorphous/crystalline heterostructure, enhanced active TiO₂ termination, and a stable SiC_x protective layer; thereby, it achieved an excellent rate stability. The Li-O₂ battery, assembled with a coal gangue/Ti₃C₂ MXene cathode catalyst, was found to obtain a competitive full discharge capacity of 3959 mAh g⁻¹ and a considerable long-term endurance of 180 h (up to 175 cycles), with a stable voltage polarization of 1.72 V at 2500 mA g⁻¹. Comprehensive characterization measurements (SEM, TEM, XPS, etc.) were applied; an in-depth analysis was conducted to reveal the critical role of TiO₂/SiC_X active units in regulating the micro-chemical constitution and the enhanced synergistic effect between coal gangue and Ti₃C₂ MXene. This work could provide considerable insights into the rational design of catalysts derived from solid waste gangue for high-rate Li-O₂ batteries. Full article
