Special Issue Information

Dear Colleagues,

It is my pleasure to invite you to submit full papers, communications, and reviews to the forthcoming Special Issue “Advance in Organic Framework Materials: Synthetic Strategies and Applications”.

Accurately controlling the assembly of functional motifs presents a significant challenge for the construction of organic framework materials, which requires the development of structurally diverse building blocks and highly reliable synthetic strategies. Porous organic materials have aroused much attention due to their modular nature and tunable structures. In particular, organic framework materials such as metal–organic frameworks (MOFs), covalent organic frameworks (COFs), hydrogen-bonded organic frameworks (HOFs), supramolecular organic frameworks (SOFs), and halogen-bonded organic frameworks (XOFs) have been widely used in the fields of gas sorption and storage, catalysis, luminescence, sensing, biomedicine, environmental remediation, energy storage, and conversion. Although there has been remarkable progress in the field of reticular chemistry over the past decade, the exploration of new synthetic strategies and applications is still in its infancy. It is also necessary to establish a fundamental understanding of the relationships between chemical structures and physicochemical properties in organic framework materials used for diverse applications. Manuscripts dedicated to the research and development of organic framework materials, especially for MOFs, COFs, HOFs, SOFs, and XOFs, will be gladly considered.

Tailoring the Microstructure of Porous Carbon Spheres as High Rate Performance Anodes for Lithium-Ion Batteries

by Zikun Liang, Ang Li, Kaiming Deng, Bo Ouyang and Erjun Kan

Abstract

Benefiting from their high surface areas, excellent conductivity, and environmental-friendliness, porous carbon nanospheres (PCSs) are of particular attraction for the anodes of lithium-ion batteries (LIBs). However, the regulation of carbon nanospheres with controlled pore distribution and graphitization for delivering high Li⁺ storage behavior is still under investigation. Here, we provide a facile approach to obtain PCSs with different microstructures via modulating the carbonization temperatures. With the processing temperature of 850 °C, the optimized PCSs exhibit an increased surface area, electrical conductivity, and enhanced specific capacity (202 mA h g⁻¹ at 2 A g⁻¹) compared to the PCSs carbonized at lower temperatures. Additionally, PCSs 850 provide excellent cyclability with a capacity retention of 83% for 500 cycles. Such work can pave a new pathway to achieve carbon nanospheres with excellent performances in LIBs. Full article

Abstract

Extensive research has been conducted on the development of high-rate and cyclic stability anodes for lithium batteries (LIBs) due to their high energy density. Molybdenum disulfide (MoS₂) with layered structure has garnered significant interest due to its exceptional theoretic Li⁺ storage behavior as anodes (670 mA h g⁻¹). However, achieving a high rate and long cyclic life of anode materials remains a challenge. Herein, we designed and synthesized a free-standing carbon nanotubes-graphene (CGF) foam, then presented a facile strategy to fabricate the MoS₂-coated CGF self-assembly anodes with different MoS₂ distributions. Such binder-free electrode possesses the advantages of both MoS₂ and graphene-based materials. Through rational regulation of the ratio of MoS₂, the MoS₂-coated CGF with uniformly distributed MoS₂ exhibits a nano pinecone-squama-like structure that can accommodate the large volume change during the cycle process, thereby significantly enhancing the cycling stability (417 mA h g⁻¹ after 1000 cycles), ideal rate performance, and high pseudocapacitive behavior (with a 76.6% contribution at 1 mV s⁻¹). Such a neat nano-pinecone structure can effectively coordinate MoS₂ and carbon framework, providing valuable insights for the construction of advanced anode materials. Full article

Abstract

Water electrolysis as an important and facile strategy to generate hydrogen has attracted great attention, and efficient electrocatalysts play a key role in hydrogen evolution reaction (HER). Herein, vertical graphene (VG)-supported ultrafine NiMo alloy nanoparticles (NiMo@VG@CC) were fabricated successfully via electro-depositing as efficient self-supported electrocatalysts for HER. The introduction of metal Mo optimized the catalytic activity of transition metal Ni. In addition, VG arrays as the three-dimensional (3D) conductive scaffold not only ensured high electron conductivity and robust structural stability, but also endowed the self-supported electrode large specific surface area and exposed more active sites. With the synergistic effect between NiMo alloys and VG, the optimized NiMo@VG@CC electrode exhibited a low overpotential of 70.95 mV at 10 mA cm⁻² and a remarkable stable performance over 24 h. This research is anticipated to offer a powerful strategy for the fabrication of high-performance hydrogen evolution catalysts. Full article

Abstract

Because of their extensive specific surface area, excellent charge transfer rate, superior chemical stability, low cost, and Earth abundance, nanostructured titanium dioxide (TiO₂) arrays have been thoroughly explored during the past few decades. The synthesis methods for TiO₂ nanoarrays, which mainly include hydrothermal/solvothermal processes, vapor-based approaches, templated growth, and top-down fabrication techniques, are summarized, and the mechanisms are also discussed. In order to improve their electrochemical performance, several attempts have been conducted to produce TiO₂ nanoarrays with morphologies and sizes that show tremendous promise for energy storage. This paper provides an overview of current developments in the research of TiO₂ nanostructured arrays. Initially, the morphological engineering of TiO₂ materials is discussed, with an emphasis on the various synthetic techniques and associated chemical and physical characteristics. We then give a brief overview of the most recent uses of TiO₂ nanoarrays in the manufacture of batteries and supercapacitors. This paper also highlights the emerging tendencies and difficulties of TiO₂ nanoarrays in different applications. Full article
