我做了CO-TPD, 具体为：
Temperature-programmed measurements were performed on a conventional CO-TPD instrument. In order to remove the pollutants adsorbed on the sample, the catalyst (0.1 g) was loaded in a quartz reactor and heated in He flow at 250 °C for 2 h; under the flowing He gas (40 mL min-1), the system was cooled to room temperature. The sample was then saturated with CO at room temperature for 0.5 h, and the excess of adsorbates were removed by allowing the sample to remain in a He flow until no significant amount of adsorbates could be detected. The temperature was ramped to 800 °C at a linear heating rate of 20 °C min-1. A Mass spectrum (MS) was used to monitor the variations of the m/e ratio of CO (28) to CO2 (44).
MS分析得到了CO 和 CO2 脱附信号
在LaMnO3催化剂CO氧化反应呢，程序升温指一定温度时，CO被LaMnO3晶格氧氧化，产生了CO2信号。

TPSR一般有两种气体，或者两者都吸附（同时或分先后），然后脱附，或者一种先吸附，另一种作为载气或和载气一起通入再程序升温
tpsr是表面反应，一般消耗多种反应气，生成物也可能有多种，需要连接ms分析，tpd就是一种反应气的化学吸附脱附，用TCD探测器就可以检测
至于CO在钙钛矿催化剂的表征，需要连接ms看看，

不可以看作是CO-TPSR吗，
希望做TPD 、TPO或TPSR的朋友留个联系方式！

TPSR是程序升温表面反应吧！
严重支持！
不能看做TPSR，不能等同，但是这个TPD信息可以给出TPSR类似的结果。
