Design and Advanced Manufacturing of NU‐1000 Metal–Organic Frameworks with Future Perspectives for Environmental and Renewable Energy Applications

Small, Journal Year: 2023, Volume and Issue: 20(15)

Published: Nov. 23, 2023

Abstract Metal–organic frameworks (MOFs) represent a relatively new family of materials that attract lots attention thanks to their unique features such as hierarchical porosity, active metal centers, versatility linkers/metal nodes, and large surface area. Among the extended list MOFs, Zr‐based‐MOFs demonstrate comparably superior chemical thermal stabilities, making them ideal candidates for energy environmental applications. As Zr‐MOF, NU‐1000 is first synthesized at Northwestern University. A comprehensive review various approaches synthesis MOFs obtaining properties (e.g., diverse morphologies, area, particular pore size distribution) applications in catalysis (electro‐, photo‐catalysis), CO 2 reduction, batteries, hydrogen storage, gas storage/separation, other fields are presented. The further outlines current challenges development derivatives practical applications, revealing areas future investigation.

Hydrogen and oxygen evolution via photocatalytic water splitting remains the quintessential alternative to fossil fuels. Photocatalysts must be sufficiently robust, competent, productive toward harnessing sunlight in order utilize solar spectrum for maximal output. Herein, we have fabricated MgIn2S4/UiO-66-NH2 composite a facile solvothermal route determined its efficacy light-induced H2 O2 generation reactions through with aid of different sacrificial agents. Initially, formation pristine materials was ascertained by PXRD, FTIR, etc. Moreover, sophisticated morphological characterization techniques (FESEM HRTEM), intricate interaction between MgIn2S4 UiO-66-NH2 revealed. Additionally, XPS studies suggested effective individual components binding energy shifting suggesting transfer electrons from Zr-MOF MgIn2S4. The PL electrochemical aspects supported photogenerated charge segregation prepared leading superior outputs. Amidst composites (3, 5, 7 wt %) MgIn2S4/UiO-66-NH2, 5 % or UM-2 displays optimal performances 493.8 258.6 μmol h-1 (4-fold greater than UiO-66-NH2), respectively. nanocomposite's enhanced performance is indeed consequence coadjuvant among that transpires Z-scheme-mediated enabling exciton channelization. inherited remarkable framework stability parent Zr-MOF, insertion had negligible impact on integrity. This work will offer valuable model developing robust Zr-MOF-based nanocomposite photocatalysts evaluating their redox reactions.
