We demonstrate the hydrothermal synthesis of three dimension (3D) peony-like morphology of zinc gallate (ZnGaO), dominated by assembled nanosheets and applied as electrode material in electrochemical detection of N,N-dimethylmethanamide chemical. The crystalline, structural and compositional characterizations deduced the formation of high quality ZnGaO with spinal crystal structure. Peony-like 3D ZnGaO was benefited by a high surface area of ~62.3 m g, good pore distribution (mean pore diameter of ~23.3 nm) and large pore volume of ~0.3622 cm g. N,N-dimethylmethanamide chemical sensor based on peony-like 3D ZnGaO electrode presented a linear curve in the working dynamic range of 1 nM-10 mM. Significantly improved chemical sensitivity of ~154.2 mA mM cm with low detection limit value of ~0.14 μM were achieved. The fabricated sensor based on peony-like 3D ZnGaO electrode endorsed real sample analysis and ascertained the selectivity towards N,N-dimethylmethanamide chemical by analyzing a range of interfering analytes, viz. ethanol, tetrahydrofuran, methyl amine chemical.
我们展示了水热合成的三维（3D）牡丹状形貌的锌镓酸盐（ZnGaO），主要由组装的纳米片组成，并应用于电化学检测 N，N-二甲基甲酰胺化学物质的电极材料。晶体、结构和组成特性推断出高质量的具有脊柱晶体结构的 ZnGaO 的形成。牡丹状 3D ZnGaO 得益于高表面积（62.3 m g）、良好的孔分布（23.3 nm 的平均孔径）和大孔体积（0.3622 cm g）。基于牡丹状 3D ZnGaO 电极的 N，N-二甲基甲酰胺化学传感器在 1 nM-10 mM 的工作动态范围内呈现线性曲线。实现了显著提高的化学灵敏度（154.2 mA mM cm）和低检测限（~0.14 μM）。基于牡丹状 3D ZnGaO 电极的制备传感器进行了实际样品分析，并通过分析一系列干扰分析物（即乙醇、四氢呋喃、甲胺化学物质）确定了对 N，N-二甲基甲酰胺化学物质的选择性。
