Tungsten oxide nanoplates with porous morphology were effectively prepared by acidification using CTAB (HexadeCetyltrimethyl ammonium bromide) as a surfactant. For characterization, the synthesized materials were subjected to X-Ray powder diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), UV–Visible spectroscopy (UV–Vis) and surface area (BET) measurements. The morphology and size of the particles were controlled by solution acidity. The BET results confirmed that the materials are well crystallized and mesoporous in nature. The nanocrystalline powder was used to prepare thick films by screen printing on alumina substrate for the investigation of gas sensing properties. The gas response measurements revealed that the samples acidified using 10 M H₂SO₄ exhibits highest response of 91% towards NO_X at optimum temperature of 200 °C for 100 ppm, and it also exhibits 35% response at room temperature.

通过使用CTAB（十六烷基十六烷基三甲基溴化铵）作为表面活性剂进行酸化，可以有效地制备具有多孔形态的氧化钨纳米板。为了表征，对合成的材料进行了X射线粉末衍射（XRD），扫描电子显微镜（SEM），高分辨率透射电子显微镜（HRTEM），紫外-可见光谱（UV-Vis）和表面积（BET）测量。颗粒的形态和尺寸由溶液酸度控制。BET结果证实该材料具有良好的结晶性和中孔性质。使用纳米晶体粉末通过在氧化铝基板上丝网印刷来制备厚膜，以研究气体感测性能。气体响应测量表明，使用10  M H ₂酸化了样品SO ₄在200 °C的最佳温度下100 ppm时对NO _X表现出91％的最高响应，在室温下也表现出35％的响应。
