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。
The adsorption and surface reaction of CO and CO-H_2 on ZrO_2 and La doped ZrO_2 were studied by FTIR and TPD techniques. Bicarbonate was observed after the adsorption of CO on ZrO_2 and La doped ZrO_2.In the case where CO-H_2 (1:2) adsorbed on La doped ZrO_2, the formate and bicarbonate were the major species formed. The desorbed substance consists of a large part of CO_2 and CO, and a small amount of CH_3OH.
