Abstract
For the first time, we are reporting the flower-like structure of copper hydroxide (Cu(OH)2) on freestanding 3D porous graphene foam (PGF). The Cu(OH)2 flowerlike structure fabricated via a simple and cost-effective chemical bath deposition (CBD) method. The CBD is a facile method which provide relatively inexpensive, simple and convenient route for large area deposition. The structural and morphological characterization of Cu(OH)2 reveals that, Cu(OH)2 flower-like structure, consists of nanorods (diameter ∼100 nm), are well covered over the porous graphene framework. The flower-like structure of copper hydroxide on PGF provides large surface area (Effective surface area = 9.44 cm2), which leads to enhancement of electrochemical activity. Significantly, Cu(OH)2/PGF electrode showed the excellent sensitivity (up to 3.36 mA mM-1 cm-2), low detection limit (1.2 μM), wide linear range (1.2 μM ∼ 6 mM). The Cu(OH)2/PGF exhibited good reproducibility and excellent selectivity toward usual interfering materials such as lactose, fructose, Acetaminophen, ascorbic acid, dopamine and urea in 1 M KOH aqueous electrolyte.
