Abstract
Plate-like heterogeneous NiO/WO₃ nanocomposites have been successfully prepared by annealing Ni(OH)₂ and H₂WO₄ in air. These NiO/WO₃ nanocomposites have shown excellent sensitivity towards NO₂ and ultrafast response at room temperature due to their p-n heterogeneous characteristics.
摘要
通过在空气中对Ni(OH)₂和H₂WO₄进行退火处理，成功制备出了片状异质结构的NiO/WO₃纳米复合材料。由于其p-n异质特性，这些NiO/WO₃纳米复合材料对NO₂表现出优异的灵敏度，并在室温下具有超快响应。
