The invention discloses the preparation of a copper-doped manganese-based catalyst with high efficiency and water resistance and its application in ozone decomposition at low concentration, belonging to the technical field of ozone purification catalyst. The efficient water-resistant ozone decomposition catalyst of the invention takes manganese and copper as active components, and the preparation method is hydrothermal method. The preparation process is to dissolve a certain amount of potassium permanganate and manganese acetate in deionized water to form a uniform solution. Then the solution of manganese acetate was slowly added into the solution of potassium permanganate and stirred evenly to form a homogeneous solution. The solid copper nitrate was added into the homogeneous solution, and the solution was stirred uniformly by ultrasound. Then the solution was transferred to the hydrothermal reactor. The reaction temperature was adjusted to 140 C for 2 hours. After the reaction, the final material was cooled naturally, centrifugally washed and dried by acid treatment. The preparation method of the invention is simple and the material is easy to obtain. At the same time, the water resistance of the catalyst is excellent, which solves the problem of water resistance of the catalyst and can adapt to various industrial production environments, and has good market application prospects.
【技术实现步骤摘要】
一种高效耐水的铜掺杂锰基催化剂的制备及其在低浓度臭氧分解中的应用
本专利技术属于臭氧净化催化剂
,更具体的说,涉及一种高效耐水的臭氧分解催化剂及其在低浓度臭氧中的治理方法。
技术介绍
近地面大气环境中的臭氧主要是由挥发性有机物和氮氧化物在光照下所产生的二次污染物。根据《广东省环境保护厅关于重点行业挥发性有机物综合整治的实施方案(2014-2017年)》(粤环[2014]130号)等文件的要求,开始对VOCs治理设施所产生的低浓度臭氧进行监管。此外,在日常生活中,人们接触到的打印机、复印机、紫外灯和各类家用电器在工作时均会向周围环境中释放少量臭氧,与大气中的臭氧叠加后可能会给人们的身体健康构成较大威胁。室内存在的低浓度臭氧则对人体有极大危害,《中国居住区大气中臭氧卫生标准》(GB18066-2000)和《室内空气中臭氧卫生标准》(GB/T18202-2000)均规定臭氧浓度不得高于100μg/m3。此外,根据美国国家环保局和世界卫生组织的相关研究,臭氧污染会对人体的呼吸系统、心血管系统、中枢神经系统等造成危害,臭氧24小时平均浓度每提升40μg/m3,会导致非 ...
