The three-dimensional flower-like structure of the CoNi-MOF\/GO nanocomposite has a multilayer structure and a large surface area, which greatly improves its electrocatalytic activity towards CC and HQ. Differential pulse voltammetry (DPV) results showed that the peak-to-peak separation of CC (0.223 V) and HQ (0.120 V) was 103 mV at a CoNi-MOF\/GO modified glassy carbon electrode (CoNi-MOF\/GO\/GCE), suggesting that the proposed modified electrode can selectively and simultaneously determine them. Under optimal conditions, the CoNi-MOF\/GO\/GCE showed an excellent analytical performance for the simultaneous determination of CC and HQ, including a wide linear range (0.1\u2013100 \u03bcM), low detection limit (0.04 \u03bcM for HQ and 0.03 \u03bcM for CC) and high anti-interference ability. As expected, the developed modified electrode has been used to analyze CC and HQ in river water, with acceptable results.<\/jats:p>","DOI":"10.3390\/s23156957","type":"journal-article","created":{"date-parts":[[2023,8,5]],"date-time":"2023-08-05T10:25:36Z","timestamp":1691231136000},"page":"6957","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Synthesis of Graphene Oxide-Coupled CoNi Bimetallic MOF Nanocomposites for the Simultaneous Analysis of Catechol and Hydroquinone"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1192-8221","authenticated-orcid":false,"given":"Shengbiao","family":"Zheng","sequence":"first","affiliation":[{"name":"College of Chemistry and Material Engineering, Anhui Science and Technology University, Bengbu 233030, China"},{"name":"Anhui Province Quartz Sand Purification and Photovoltaic Glass Engineering, Research Center, Bengbu 233030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nini","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Chemistry and Material Engineering, Anhui Science and Technology University, Bengbu 233030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liang","family":"Li","sequence":"additional","affiliation":[{"name":"College of Chemistry and Material Engineering, Anhui Science and Technology University, Bengbu 233030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianna","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Chemistry and Material Engineering, Anhui Science and Technology University, Bengbu 233030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuyang","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Chemistry and Material Engineering, Anhui Science and Technology University, Bengbu 233030, China"},{"name":"Anhui Province Quartz Sand Purification and Photovoltaic Glass Engineering, Research Center, Bengbu 233030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Tang","sequence":"additional","affiliation":[{"name":"College of Chemistry and Material Engineering, Anhui Science and Technology University, Bengbu 233030, China"},{"name":"Anhui Province Quartz Sand Purification and Photovoltaic Glass Engineering, Research Center, Bengbu 233030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiahao","family":"Guo","sequence":"additional","affiliation":[{"name":"College of Chemistry and Material Engineering, Anhui Science and Technology University, Bengbu 233030, China"},{"name":"Anhui Province Quartz Sand Purification and Photovoltaic Glass Engineering, Research Center, Bengbu 233030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9399-8249","authenticated-orcid":false,"given":"Shao","family":"Su","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Organic Electronics and Information Displays & Jiangsu Key Laboratory for Biosensors, Institute of Advanced Materials (IAM), Nanjing University of Posts and Telecommunications, Nanjing 210023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2221","DOI":"10.1002\/elan.201500114","article-title":"Simultaneous and highly sensitive determination of hydroquinone and catechol using carboxyl functionalized graphene self-assembled monolayers","volume":"27","author":"Li","year":"2015","journal-title":"Electroanalysis"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"677","DOI":"10.1016\/j.electacta.2017.02.060","article-title":"Ultrasensitive and simultaneous detection of hydroquinone, catechol and resorcinol based on the electrochemical co-reduction prepared Au-Pd nanoflower\/reduced graphene oxide nanocomposite","volume":"231","author":"Chen","year":"2017","journal-title":"Electrochim.
