Special Issue Information

Dear Colleagues,

Metal–organic frameworks (MOF) composed of various metal centers and ligands are a hot research topic. MOFs present tunable composition and rich structural diversity beyond conventional solid-state materials. These features endow them to be used in a wide potential application field such as adsorptive separation/storage of hydrocarbon mixtures with MOF-based membranes or columns, and catalysis for various important chemical processes. Especially, with Nano/Micro MOF precursors, some interesting materials with special compositions and structures can be obtained, which would be difficult to be obtained by conventional methods. These Nano/Micro MOF-derived materials show excellent performance and potential applications when used in energy-related processes or devices.

This Special Issue of Chemistry is intended to present the recent advances in Nano/Micro MOF-based materials for energy conversion and storage. Authors are encouraged to submit various types of articles addressing this theme in this Special Issue. Topics include, but are not limited to Nano/Micro MOF-related materials for the following issues:

1)  Supercapacitors;

2)  Electrocatalysis;

3)  Batteries;

4)  CO2 capture/N2 reduction;

5)  Gas storage;

6)  Design, synthesis, and characterization.

Please note that invited manuscripts do not guarantee their final acceptance, all submitted manuscripts will undergo vigorous external evaluation.

Abstract
This study successfully prepared a hierarchically porous ZIF-67 (H-ZIF-67) by incorporating the polyvinylpyrrolidone (PVP) at room temperature. Compared to standard control ZIF-67 (C-ZIF-67) with a yield of 81% and a BET specific surface area of 1228 m2·g−1, the H-ZIF-67 [...] Read more.
This study successfully prepared a hierarchically porous ZIF-67 (H-ZIF-67) by incorporating the polyvinylpyrrolidone (PVP) at room temperature. Compared to standard control ZIF-67 (C-ZIF-67) with a yield of 81% and a BET specific surface area of 1228 m2·g−1, the H-ZIF-67 not only exhibited improved crystallinity and pore structure but also achieved a yield of up to 93% and a BET specific surface area of 1457 m2·g−1. Due to its hierarchically porous structure, H-ZIF-67 demonstrated excellent adsorption capacity and efficiency for methylene orange (MO). Additionally, the composite separator created by combining H-ZIF-67 with nanocellulose (CNF) exhibited remarkable uniformity and dispersion in zinc batteries. In comparison to a conventional CNF separator, the porous structure and high specific surface area of H-ZIF-67 significantly enhanced its electrolyte wettability and Zn2+ transport rates. Its abundant Lewis acid sites effectively promoted the uniform deposition of Zn2+, thereby suppressing the formation of zinc dendrites and improving the cycling and safety performance of zinc-ion batteries. Experimental results indicate that the ion conductivity of the membrane was 4.31 mS·cm−1, the electrolyte absorption rate was 316%, and it could cycle stable for over 4000 h at a current density of 1 mA·cm−2 with a discharge capacity of 1 mAh·cm−2. This achievement will open up new avenues for the preparation and application of ZIF-67 composite separators in aqueous zinc-ion batteries. Full article

The metal–organic framework (MOF) is a kind of porous material with lattice materials. Due to its large surface area and structural diversity, it has made great progress in the fields of batteries, capacitors, electrocatalysis, etc. Conductive MOF (c-MOF) increases the conductivity based on the original advantages of the MOF, which is more suitable for the development of batteries, capacitors, electrocatalysis, and other fields. This review summarizes the preparation of c-MOF and the research progress of conductive MOFs in the field of electrochemical energy storage and conversion. Full article
