An efficient strategy to synthesize Zn-Co-S BHS consisted of multilevel structures by controlling the ionic exchange reaction was applied to obtain great performance electrode material. Carbon nanotubes (CNTs) as a conductive agent were uniformly introduced with Zn-Co-S BHS to form Zn-Co-S BHS\/CNTs and expedited the considerable electrocatalytic behavior toward glucose electro-oxidation in alkaline medium. In this study, characterization with scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD) was used for investigating the morphological and physical\/chemical properties and further evaluating the feasibility of Zn-Co-S BHS\/CNTs in non-enzymatic glucose sensing. Electrochemical methods (cyclic voltammetry (CV) and chronoamperometry (CA)) were performed to investigate the glucose sensing performance of Zn-Co-S BHS\/CNTs. The synergistic effect of Faradaic redox couple species of Zn-Co-S BHS and unique conductive network of CNTs exhibited excellent electrochemical catalytic ability towards the glucose electro-oxidation, which revealed linear range from 5 to 100 \u03bcM with high sensitivity of 2734.4 \u03bcA mM\u22121 cm\u22122, excellent detection limit of 2.98 \u03bcM, and great selectivity in the presence of dopamine, uric acid, ascorbic acid, and fructose. Thus, Zn-Co-S BHS\/CNTs would be expected to be a promising material for non-enzymatic glucose sensing.<\/jats:p>","DOI":"10.3390\/s20154340","type":"journal-article","created":{"date-parts":[[2020,8,4]],"date-time":"2020-08-04T05:56:46Z","timestamp":1596520606000},"page":"4340","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Non-Enzymatic Glucose Sensing Based on Incorporation of Carbon Nanotube into Zn-Co-S Ball-in-Ball Hollow Sphere"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3457-6975","authenticated-orcid":false,"given":"Han-Wei","family":"Chang","sequence":"first","affiliation":[{"name":"Department of Chemical Engineering, National United University, 2, Lienda, Miaoli 36063, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chia-Wei","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, National Chung Hsing University, 145 Xingda Road, Taichung 402, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia-Hao","family":"Tian","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, National Chung Hsing University, 145 Xingda Road, Taichung 402, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Chen","family":"Tsai","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, National Chung Hsing University, 145 Xingda Road, Taichung 402, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,4]]},"reference":[{"key":"ref_1","unstructured":"Atlas, I.D.
