【摘要】 <正>前言:利用CO,NO作为探针分子研究HDS催化剂活性相结构以及活性相之间相互作用已经有许多报导但是直接利用反应物分子如C₄H₄S等作为探针分子来研究HDS催化剂至今尚未见报导,因此,本研究目的是利用C₄H₄S吸附和C₄H₄同NO或CO共吸附的红外光谱来考察活性相前身态的性质和相互作用,并且获得了C₄H₄S及附模型的信息.更多还原

【Abstract】 Infrared spectra of co-adsorbed of thiophene with CO and NO on Co-Mo/ Al₂O₃,Co/Al₂O₃,Mo/Al₂O₃ have been invistigated.It was found that thiophene adsorb on both Co-sites and Mo-sites with S-atom,adsorption of thiophene on CoMo/ Al₂O₃ is similar to that of thiophene on Al₂O₃,however,adsorption of thiophene on Mo-site is weaker than that on Al₂O₃,and ability of Mo-sites to adsorb thiophene is stronger than that of Co-sites.更多还原
