【摘要】 低浓度CO氧化是催化领域的重要研究方向之一,在大气污染治理、CO气体防护面具、燃料电池气体净化、CO气体传感器、封闭式CO2激光器等方面具有重要应用前景。近年来,我们课题组采用胶体沉积法制备出Pt/FeOx催化剂,该催化剂具有良好的CO低温催化氧化性能[1,2]。利用原位红外光谱监测Pt/FeOx催化剂上的低温CO氧化反应过程,研究结果发现氧气活化能力对Pt/FeOx催化剂的低温CO催化性能影响较大。更多还原

【Abstract】 Low concentration of CO oxidation is one of the most important researches for the catalysis,and has important prospect in air pollution control,CO gas masks,fuel cell gas purification,CO gas sensor and closed type CO2 laser.In recent years,we prepared the Pt/FeOxcatalyst by colloid deposition method,which has an excellent catalytic performance in low temperature CO oxidation.In this paper,the low temperature CO oxidation reaction on Pt/FeOxcatalyst was monitored by in situ infrared spectroscopy.The results show that the oxygen activation ability has great influence on the low temperature CO catalytic performance of Pt/FeOxcatalyst.更多还原
