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.

Amide Covalent Bonding Engineering in Heterojunction for Efficient Solar-Driven CO₂ Reduction

ACS Nano, Journal Year: 2023, Volume and Issue: 17(20), P. 20560 - 20569

Published: Oct. 4, 2023

Inefficient charge separation and slow interfacial reaction dynamics significantly hamper the efficiency of photocatalytic CO2 reduction. Herein, a facile EDC/NHS-assisted linking strategy was developed to enhance in heterojunction photocatalysts. Using this approach, we successfully synthesized amide-bonded carbon quantum dot-g-C3N4 (CQD-CN) The formation amide covalent bonds between CN CQDs CN-CQD facilitates efficient carrier migration, adsorption, activation. Exploiting these advantages, photocatalysts exhibit high selectivity with CO CH4 evolution rates 79.2 2.7 μmol g-1 h-1, respectively. These are about 1.7 3.6 times higher than those CN@CQD bulk CN, Importantly, demonstrate exceptional stability, even after 12 h continuous testing. presence COOH* signal is identified as crucial intermediate species conversion CO. This study presents bonding engineering for developing high-performance solar-driven reduction CO2.
