Abstract

A wide range of industrial, environmental, and biomedical applications depend greatly on the development of sensitive and reliable humidity sensors. This work reports an extensive investigation of a nanostructured surfactant such as Sodium Dodecyl Sulfate (SDS) and Cetyltrimethyl Ammonium Bromide (CTAB) activated mixed metal oxide (Zinc Oxide / Nickel Oxide) nanomaterial. The crystal study demonstrates an increase in the ZnO/NiO characteristic peaks (101) and (200), due to surface reactive agents. The increment of CTAB molar ratio has significantly increased the crystallite size, such that the bandgap of ZnO/NiO composite is reduced from 3.37eV to 2.80 eV. Brunauer-Emmitt-Teller (BET) surface area study revealed the production of a mesoporous ZnO with an improvement in the specific surface area from 7.82 to 52.01 m ² g ⁻¹ with a mean diameter reducing from 22.28 to 18.94 nm for the CTAB molar concentration range of 0.0, 0.5, 1.0, 1.5 and 2.0 M namely SC-1, SC-2, SC-3, SC-4, and SC-5 respectively. The internal resistance achieved for the 2M sample is 1 KΩ, which is suitable for better humidity and gas sensing properties. Hence, the proposed ZnO/NiO metal oxide material is more sensitive to a plurality of analytes by providing an increased BET surface area.

表面活性剂活化混合金属氧化物 (MMO) 纳米材料的实验研究与表征

广泛的工业、环境和生物医学应用在很大程度上依赖于灵敏可靠的湿度传感器的开发。本研究报告对十二烷基硫酸钠（SDS）和十六烷基三甲基溴化铵（CTAB）等纳米结构表面活性剂激活的混合金属氧化物（氧化锌/氧化镍）纳米材料进行了广泛研究。晶体研究表明，由于表面活性剂的作用，氧化锌/氧化镍特征峰（101）和（200）有所增加。CTAB 摩尔比的增加显著增大了晶粒尺寸，从而使氧化锌/氧化镍复合材料的带隙从 3.37eV 减小到 2.80eV。布鲁瑙尔-艾美特-泰勒（BET）表面积研究表明，在 CTAB 摩尔浓度分别为 0.0、0.5、1.0、1.5 和 2.0 M（即 SC-1、SC-2、SC-3、SC-4 和 SC-5）的范围内，产生了介孔 ZnO，比表面积从 7.82 m2g-1 增加到 52.01 m2g-1，平均直径从 22.28 nm 减小到 18.94 nm。2M 样品的内阻为 1 KΩ，适用于更好的湿度和气体传感特性。因此，拟议的 ZnO/NiO 金属氧化物材料通过提供更大的 BET 表面积，对多种分析物更加敏感。
