Low-Temperature O3 Decomposition over Pd-TiO2 Hybrid Catalysts

In aircraft and spacecraft, outside air is not directly fed to the passenger because it contains ozone at elevated altitudes. The decomposition of low concentration in was carried out 25 °C by catalytic oxidation on Pd-based catalysts supported a high surface area hybrid TiO2. use these has shown beneficial effect, both activity catalyst stability. Kinetic studies showed that most promising phase (Pd/TiO2_100) one obtained from TiO2 support containing lowest content citrate ligands leading small Pd particles (around 4 nm). effect synthesis O3 gas (15 ppm) dry humid (HR = 10%) stream closed environment such as or spacecraft also investigated this study further elucidated detailed characterizations. It system could be used an effective treatment for coming outside.
