Kung C.-W.Li Y.-S.Lee M.-H.Wang S.-Y.Chiang W.-H.Ho K.-C.2019-05-172019-05-17201620507488https://scholars.lib.ntu.edu.tw/handle/123456789/408682Graphene nanoribbons (GNRs) are incorporated with the nanocrystals of a porphyrinic metal-organic framework, MOF-525, by solvothermally growing MOF-525 in a suspension of well-dispersed GNRs. A nanocomposite, which is composed of the MOF-525 nanocrystals interconnected by numerous one-dimensional GNRs, is successfully synthesized. Due to the excellent dispersity, uniform thin films of the MOF-525/GNR nanocomposite can be simply deposited on conducting glass substrates by using drop casting. The obtained thin film of the MOF-525/GNR nanocomposite is applied for electrochemical nitrite sensors. The MOF-525 nanocrystals serve as a high-surface-area electrocatalyst toward nitrite and the interconnected GNRs act as conductive bridges to provide facile charge transport. The thin film of the MOF-525/GNR nanocomposite thus exhibits a much better electrocatalytic activity for the oxidation of nitrite compared to the pristine MOF-525 thin film. ? 2016 The Royal Society of Chemistry.journal article10.1039/c6ta02563c2-s2.0-84978139100https://www.scopus.com/inward/record.uri?eid=2-s2.0-84978139100&doi=10.1039%2fc6ta02563c&partnerID=40&md5=e8bcd8a480d2ee52435db4bc1042e7be
