Here, we have proposed a new idea: to construct a sensor for the rapid determination of hydrazine hydrate based on the nano-CuO derived by controlled pyrolysis of HKUST-1 [Cu3(BTC)2(H2O)3]. The as-prepared CuO at 400 \u00b0C possesses a uniform appearance with nano-structure via SEM images, and the nano-CuO-400 has exhibited excellent electrocatalytic activity towards hydrazine oxidation. Amperometric i-t curves shows the peak current as linearly proportional to the hydrazine concentration within 1.98\u2013169.3 \u03bcmol L\u22121 and 232\u20132096 \u03bcmol L\u22121 with the detection limit of 2.55 \u00d7 10\u22128 mol L\u22121 and 7.01 \u00d7 10\u22128 mol L\u22121, respectively. Moreover, the sensor constructed in the experiment shows good selectivities, and it is feasible to determining actual water samples.<\/jats:p>","DOI":"10.3390\/s20010140","type":"journal-article","created":{"date-parts":[[2019,12,24]],"date-time":"2019-12-24T10:28:43Z","timestamp":1577183323000},"page":"140","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["MOFs-Derived Nano-CuO Modified Electrode as a Sensor for Determination of Hydrazine Hydrate in Aqueous Medium"],"prefix":"10.3390","volume":"20","author":[{"given":"Yaqi","family":"Lu","sequence":"first","affiliation":[{"name":"Fujian Provincial Key Laboratory of Polymer Materials, College of Chemistry and Materials Science, Fujian Normal University, 32 Shangsan Road, Fuzhou 350007, China"},{"name":"College of Chemistry and Materials Science, Longyan University, No.1 North Dongxiao Rd., Longyan 364012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dan","family":"Wu","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Polymer Materials, College of Chemistry and Materials Science, Fujian Normal University, 32 Shangsan Road, Fuzhou 350007, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziyin","family":"Li","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Polymer Materials, College of Chemistry and Materials Science, Fujian Normal University, 32 Shangsan Road, Fuzhou 350007, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Quanjie","family":"Lin","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Polymer Materials, College of Chemistry and Materials Science, Fujian Normal University, 32 Shangsan Road, Fuzhou 350007, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiuling","family":"Ma","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Polymer Materials, College of Chemistry and Materials Science, Fujian Normal University, 32 Shangsan Road, Fuzhou 350007, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhangjing","family":"Zhang","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Polymer Materials, College of Chemistry and Materials Science, Fujian Normal University, 32 Shangsan Road, Fuzhou 350007, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shengchang","family":"Xiang","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Polymer Materials, College of Chemistry and Materials Science, Fujian Normal University, 32 Shangsan Road, Fuzhou 350007, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1039\/b010091a","article-title":"Synthetic methodology for alkyl substituted hydrazines","volume":"30","author":"Ragnarsson","year":"2001","journal-title":"Chem.
