摘　　要：本文采用无表面活性剂添加的液相回流法合成了边长约为300～600 nm、表面粗糙的氧化亚铜立方体。并且在室温下,对氧化亚铜立方体的NOx气敏性检测研究发现,该材料对NOx有很较好的气敏响应,最低检测限可达0.97 ppm,响应时间为69 s,是一种有潜力的气敏材料。In this paper, the cuprous oxide cube was synthesized by no surface active agent added liquid reflux method, whieh has rough surface and the side length is about 300-600 nm. The gas sensing property of the cuprous oxide cube on NO, were detected at room temperature, the research shows the material has good gas sensing response on NOx, the lowest detection limit is 0.97 ppm, and the response time is less than 1 min. All the results suggest the cube cuprous oxide is a potential gas - sensitive material.
