Special Issue Information

Dear Colleagues,

The development of materials for energy storage and conversion is essential for the battle toward a sustainable future. Among such emerging materials, metal–organic frameworks (MOFs) and covalent–organic frameworks (COFs) have shown great potential for such applications. MOFs and COFs are both porous materials. MOFs are constructed by linking multidentate ligands with metal/cluster nodes to form infinite crystalline networks, while COFs are solely organic frameworks connected by covalent bonds with better thermal and chemical stability. They share the common feature of high surface area, permanent porosity, and tunable structures and can act as excellent precursors to obtain hierarchical nanostructures, which have a significant impact on the performance in energy-related applications.

The main aim of this Special Issue of Materials is to provide an overview of the recent development and understanding in the field of MOF/COFs and their derived materials for energy storage (hydrogen storage, batteries, and supercapacitors) and conversion (solar cell and fuel cells, adsorption-driven heat-pumps and chillers, electrocatalysts, as well as photocatalysts). The development of the synthetic strategy as well as morphological control in MOF/COFs and their related hybrid materials are also fits in this theme.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Samples of the bimetallic-based NH2-MIL-125(Ti) at a ratio of Mn+/Ti4+ is 0.15 (Mn+: Ni2+, Co2+ and Fe3+) were first synthesized using the solvothermal method. Their fundamental properties were analyzed by X-ray [...] Read more.
Samples of the bimetallic-based NH2-MIL-125(Ti) at a ratio of Mn+/Ti4+ is 0.15 (Mn+: Ni2+, Co2+ and Fe3+) were first synthesized using the solvothermal method. Their fundamental properties were analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectra, scanning electron microscopy (SEM), N2 adsorption–desorption measurements, and UV–Vis diffuse reflectance spectroscopy (UV-Vis DRS). The as-acquired materials were used as high-efficiency heterogeneous photocatalysts to remove Rhodamine B (RhB) dye under visible light. The results verified that 82.4% of the RhB (3 × 10−5 M) was degraded within 120 min by 15% Fe/Ti−MOFs. Furthermore, in the purpose of degrading Rhodamine B (RhB), the rate constant for the 15% Fe/Ti-MOFs was found to be 2.6 times as fast as that of NH2-MIL-125(Ti). Moreover, the 15% Fe/Ti-MOFs photocatalysts remained stable after three consecutive cycles. The trapping test demonstrated that the major active species in the degradation of the RhB process were hydroxyl radicals (HO) and holes (h+). Full article
