Journal ArticleDOI
Metal-Organic Frameworks for Chemiresistive Sensors
TL;DR: A comprehensive overview and recent progress in chemiresistive sensors developed by using pure metal-organic frameworks (MOFs), MOF membranes, and MOF derivatives can be found in this article.
Journal ArticleDOI
Heterogeneous Sensitization of Metal-Organic Framework Driven Metal@Metal Oxide Complex Catalysts on an Oxide Nanofiber Scaffold Toward Superior Gas Sensors.
TL;DR: It is demonstrated that MOF-derived M@MO complex catalysts can be functionalized within an electrospun nanofiber scaffold, thereby creating multiheterojunctions, essential for improving catalytic sensor sensitization.
Journal ArticleDOI
Nanoscale PdO Catalyst Functionalized Co3O4 Hollow Nanocages Using MOF Templates for Selective Detection of Acetone Molecules in Exhaled Breath
TL;DR: The novel synthesis of MOF templated nanoscale catalyst loaded SMO HNCs for high performance gas sensors showed high acetone selectivity against other interfering gases and clearly distinguished simulated exhaled breath of diabetics from healthy people's breath.
Journal ArticleDOI
Accelerating Palladium Nanowire H2 Sensors Using Engineered Nanofiltration
Won-Tae Koo,Shaopeng Qiao,Alana F. Ogata,Gaurav Jha,Ji-Soo Jang,Vivian T. Chen,Il-Doo Kim,Reginald M. Penner +7 more
TL;DR: Outstanding results are described, which are mainly attributed to the molecular sieving and acceleration effect of ZIF-8 covered on Pd NWs, rank highest in H2 sensing speed among room-temperature Pd-based H2 sensors.
Journal ArticleDOI
Metal–Organic Framework Templated Catalysts: Dual Sensitization of PdO–ZnO Composite on Hollow SnO2 Nanotubes for Selective Acetone Sensors
TL;DR: Metal-organic framework (MOF)-derived synergistic catalysts were easily functionalized on hollow SnO2 nanotubes (NTs) via electrospinning and subsequent calcination and exhibited high acetone response, superior acetone selectivity against other interfering gases, and fast response and recovery under highly humid atmosphere.
