Three-dimensional (3D) flower-like controllable microstructures of nickel tungsten oxide (NiWO4) were synthesized by using a surfactant free wet chemical method at low temperature (60 °C). The uniform morphologies of NiWO4 were molded by adjusting the temperature, stirring rate, and dosage of hydrazine in aqueous solution. We reported immediate precipitation of the 3D NiWO4 microflowers (MFs) by introducing hydrazine monohydrate (N2H4·H2O). This approach resulted in a better yield and shortened the reaction time. In this work, we investigated the probable mechanism behind the formation of flower-like microstructures. Furthermore, the flower-like microstructure was assessed for its electrochemical properties towards non-enzymatic glucose sensing by addition of 50 μL of a glucose solution (50 μM) in an electrolyte (0.1 M NaOH) using glassy carbon electrode.

无表面活性剂湿化学方法的形态控制合成3D花状NiWO 4微观结构

采用无表面活性剂的湿法化学方法,在低温(60°C)下,合成了氧化镍钨(NiWO 4)的三维(3D)花状可控微观结构。通过调节温度,搅拌速率和水溶液中肼的用量,可以成型出均匀的NiWO 4形貌。我们报道了3D NIWO的立即沉淀4通过引入一水合肼(N microflowers(MFS)2 ħ 4 ·H 2O)。该方法导致更好的收率并缩短了反应时间。在这项工作中,我们调查了花状微结构形成背后的可能机制。此外,通过使用玻璃碳电极在电解质(0.1 M NaOH)中添加50μL葡萄糖溶液(50μM),评估了花状微结构对非酶促葡萄糖感应的电化学性能。
