利用红外光谱技术考察了吸电性添加物(Cl~-,Br~-和I~-)及给电性添加物(Na_2O和K_2O)对CO在Ru/Al_2O_3催化剂上吸附态的影响。发现添加物不同时,CO吸收谱带的数目、位置及强度均有变化。同时考察了添加物浓度和吸附温度的影响,观察到添加物Cl~-与残留Cl~-对CO吸附的不同作用。
The influence of CO (Cl ~ -, Br ~ - and I ~ -) and feed additives (Na_2O and K_2O) on the adsorption of CO on Ru / Al_2O_3 catalyst was investigated by infrared spectroscopy. When the additives were found to be different, the number, location and intensity of CO absorption bands varied. At the same time, the effect of additive concentration and adsorption temperature was investigated. The different effects of Cl ~ - and residual Cl ~ on CO adsorption were observed.
