Special Issue Information

Dear Colleagues,

Porous materials have shown great potential in catalysis, biosensor and biomedical, energy storage and conversion, aerospace, and architecture applications owing to their high surface area, low density, and high specific strength. Porous materials have the structural feature of continuous interconnected porosity, which benefits the transport of electrons, ions, and mass. The chemical compositions of porous materials are well-controlled and diversified and include metals, ceramics, and carbon-based materials. As a result, the development of porous materials is quickly becoming important. An increasing number of researchers are working from different perspectives to conduct fundamental research on various applications.

This Special Issue focuses on recent advances in various porous materials. Research areas include but are not limited to novel synthetic strategies, advanced characterization skills, theoretical calculation methods, and various applications. We encourage you to submit a manuscript to this Special Issue. Original research papers and review articles are welcome. We look forward to receiving your contributions.

Through an activation reaction sintering method, porous (Mo2/3Y1/3)2AlC ceramics were prepared by Mo, Y, Al, and graphite powders as raw materials. The phase composition, microstructure, element distribution, and pore structure characteristics were comprehensively studied using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), Archimedes method, and bubble point method. A detailed investigation was conducted on the influence of sintering temperature on the phase composition. Possible routes of phase transition and pore formation mechanisms during the sintering process were provided. The experimental results reveal that at 650–850 °C, transition metals react with aluminum, forming aluminum-containing intermetallics and a small amount of carbides. At 850–1250 °C, transition metals collaborate with graphite, producing transition metal carbides. Then, at 1250–1450 °C, these aluminum intermetallics interact with transition metal carbides and remaining unreacted Y, Al, and C, yielding the final product (Mo2/3Y1/3) 2AlC. Simultaneously, the pore structure alters correspondingly with the solid-phase reaction at different reaction temperatures. Full article

High-entropy oxides (HEOs), as a new type of single-phase solid solution with a multi-component design, have shown great potential when they are used as anodes in lithium-ion batteries due to four kinds of effects (thermodynamic high-entropy effect, the structural lattice distortion effect, the kinetic slow diffusion effect, and the electrochemical “cocktail effect”), leading to excellent cycling stability. Although the number of articles on the study of HEO materials has increased significantly, the latest research progress in porous HEO materials in the lithium-ion battery field has not been systematically summarized. This review outlines the progress made in recent years in the design, synthesis, and characterization of porous HEOs and focuses on phase transitions during the cycling process, the role of individual elements, and the lithium storage mechanisms disclosed through some advanced characterization techniques. Finally, the future outlook of HEOs in the energy storage field is presented, providing some guidance for researchers to further improve the design of porous HEOs. Full article
