Construction of Pt decorated CeO2 nanocomposite for efficient VOCs catalytic oxidation and atmospheric total organic carbon dictation
Year: 2023
Type: article
Abstract: Toluene, dichloromethane, and methanethiol were selected as probe molecules for aromatic, chlorinated, and sulfurated VOCs, respectively, to evaluate the catalytic properties of Pt/CeO2 composites. The T90 for toluene, DCM, and methanethiol oxidation were only 153, 265, and 240 °C, when 0.9 wt% Pt/CeO2 was used as the catalyst. The synergy between Pt and support could be responsible for the high catalytic activity and antipoisoning properties. When combined with NDIR CO2 sensors, the composite could be used for atmospheric total organic carbon detection. The recorded data almost overlap with that of the theoretical, suggesting the excellent reliability of the dictation system.
