【摘要】 采用傅里叶红外光谱和程序升温脱附技术研究了CO和CO-H₂在ZrO₂和Zr、La复合氧化物上的吸脱附行为及表面反应.CO吸附在ZrO₂和Zr、La复合氧化物上,红外谱图呈现出1609和1560cm^-1谱带,归属于HOCOO^-.CO:H₂（1:2）共吸附在Zr、La复合氧化物催化剂上,除呈现上述谱带外,还有1589、1390和1360cm^-1谱带,应归属于HCOO^-.脱附物主要是CO和CO₂,还有少量CH₂OH。更多还原

【Abstract】 The adsorption and surface reaction of CO and CO-H₂ on ZrO₂ and La doped ZrO₂ were studied by FTIR and TPD techniques. Bicarbonate was observed after the adsorption of CO on ZrO₂ and La doped ZrO₂.In the case where CO-H₂ （1:2） adsorbed on La doped ZrO₂, the formate and bicarbonate were the major species formed. The desorbed substance consists of a large part of CO₂ and CO, and a small amount of CH₃OH.更多还原
