Oct 13, 2020 · Monometallic and bimetallic MOF-74-M (M = Mn, Co, Ni, Zn, MnCo, MnNi, and MnZn) catalysts were prepared by the solvothermal method for NH 3-SCR. XRD, BET, SEM, and EDS-mapping tests indicate the successful synthesis of the MOF-74-M catalyst with uniform distribution of metal elements and large specific surface area, and the morphology is almost ...

Jul 15, 2019 · MOF-74 can be synthesized directly from a metal oxide and without bulk solvent, which not only saves a lot of time and money, but also is more ecological. The mesopores in MOF-74 can be adjusted to as large as 15 nm stably at room temperature.

Apr 25, 2023 · Defects in metal-organic frameworks impact their structure and properties. Here authors uncover formate defects in MOF-74 that originate from decomposed DMF solvent.

MOF-74-type frameworks are considered one of the most promising metal–organic frameworks owing to their remarkable structural features and properties such as a high density of open metal sites, hexagonal channels along the c-axis, and high porosity.

Feb 24, 2014 · ABSTRACT: Metal organic frameworks (MOFs) contain-− ing more than two kinds of metal ions mixed in one secondary building unit are rare because the synthesis often yields mixed MOF phases rather than a pure phase of a mixed-metal MOF (MM-MOF).

Sep 23, 2016 · M-MOF-74 (M = Mn and Co), especially Mn-MOF-74, showed excellent catalytic performance for low-temperature SCR. In addition, in the reaction process, NO conversion on Mn-MOF-74 decreased with the introduction of H 2 O and SO 2 …

Jan 1, 2018 · The MOF-74 is resulted from the combination of divalent metallic cations with the divergent organic ligand 2,5-dihydroxybenzene-1,4-dicarboxylate (DBDC). A wide diversity of materials can be synthetized based on the topology of MOF-74.

Apr 1, 2025 · Various synthesis methods of MOF-74 composites have been discussed. The review outlines the broad applications of MOF-74 and its composites for energy and environment. A detailed analysis of the catalytic performance of MOF-74 is provided. Current challenges and future perspectives were identifies.

In this work, for the first time, MOF-74 materials with different divalent metal ions have been synthesized directly on carbon fiber, one of the most widely used materials for the preparation of electrodes for supercapacitors with structural properties.

Jul 17, 2024 · By replacing Zn 2+ ions with Ti 4+ ions in a substitutional manner, researchers have aimed to enhance the photocatalytic activity of the CO 2 reduction. The obtained Ti 4+ -doped MOF-74 photocatalysts exhibited a significantly improved performance in the reduction of CO 2 into carbon monoxide (CO).
