Preparation of hierarchical Co(OH)2 nanotube arrays grown on carbon cloth and its use in non-enzymatic glucose sensing

Abstract

Hierarchical Co(OH)2 nanotube arrays grown oncarbon cloth (Co(OH)2 NTAs/CC) was prepared by a simple two-step approach. Firstly, the layered cobalt carbonate hydroxide nanowire arrays grown on carbon cloth (LCCH NWAs/CC) were prepared by chemical bath deposition. Then, the obtained LCCH NWAs/CC was converted to Co(OH)2 nanotube arrays supported on CC (Co(OH)2NTAs/CC) through anion-exchange reaction. Benefiting from the hierarchical structure of nanotube arrays and 3D self-supported construction, Co(OH)2 NTAs/CC shows high performance for non-enzymatic glucose sensing with a wide linear ranger from 1 μM to 0.6 mM, a remarkable sensitivity of 2.77 mAmM−1cm−2, a low detection limit of 0.5μM (S/N = 3), a good selectivity against common interferences, and a reliability for glucose detection in human serum samples.
