摘　　要：采用密闭实验舱模拟舰艇舱室环境。以分子筛负载纳米TiO2的分解效率为依据,考察了其对甲醛的催化分解性能。结果表明,纳米TiO2的分解效率随着温度的上升而显著提高,随湿度的升高而降低,光照强度对纳米TiO2的催化效能影响不大,而过高的甲醛初始浓度也会降低纳米TiO2的分解效率。Simulated vessel cabin environment using closed JEM.The decomposition efficiency of nano-TiO2 Zeolites was chosen as criterion to determine the performance of catalytic decomposition to formaldehyde.The results showed that the decomposition efficiency of the nano-TiO2 increased significantly as temperature rised,reduces with the rise of humidity.And the light intensity had little effect on the decomposition efficiency.However,too high initial concentration of formaldehyde could also reduce the decomposition efficiency of nano-TiO2.
