Published: Feb. 24, 2025

Nitric oxide is an endogenous biological signaling molecule, and the corresponding fractional exhaled NO serves as important indicator in clinical diagnostics therapeutic applications. However, achieving accurate rapid monitoring of ppb-level nitric (FeNO) at room temperature remains a significant challenge. Herein, ultrathin porphyrin metal-organic framework (MOF) sheets are selected to assemble with supramolecularly functionalized graphene through hydrogen bonding electrostatic interaction 6 nm thickness. The resulting MOF/graphene sheet-on-sheet nanohybrid designed chemiresistive sensor which exhibits superior gas sensing performance including ultralow practical limit detection (Ra/Rg = 1.047, 5 ppb NO), reliable repeatability, excellent selectivity against other gases, relative long-term stability. Mechanism study indicates that prominent attributed ordered active sites ferric-pyrrole (Fe─N4) less than 10 thick heterojunction structure nanohybrid. potential utility obtained sensors validated by exhalation tests toward samples from healthy individuals asthma patients, respectively. This work provides effective strategy developing MOF-based for FeNO monitoring.

ZIF-67 Clusters with Small-Size Particles Confined by a Graphene Framework as a Promising Lithium-Ion Battery Anode

ACS Omega, Journal Year: 2025, Volume and Issue: unknown

Published: April 9, 2025

Composites based on metal-organic frameworks (MOFs), which feature a distinctive porous structure, are regarded as one of the leading candidates for anodes in future lithium-ion batteries (LIBs). However, their poor conductivity and structural pulverization effect hinder widespread application LIBs. In this study, we reported new strategy that confines nanoporous ZIF-67 clusters within flexible graphene (ZIF-67@rGO) through solvothermal annealing processes. The confinement small-size structure helps to relieve volume maintain stability composites. Additionally, framework facilitates shorter pathways rapid charge transmission significantly boosts electrode. Therefore, resulting 3D ZIF-67@rGO composite was directly pressed binder-free LIB anode, delivering an ultrahigh capacity 1429 mAh g-1 after 150 cycles at 0.1 A superlong cycle performance 1002 2500 2 g-1. By combining experimental studies GITT analysis, kinetic behavior lithium storage anode LIBs described. This work may open avenue research other MOF-based composites electrodes energy conversion.
