摘要
基于催化剂多活性中心分工协同作用可活化两种或多种反应物,本研究工作以一种新的制备策略对贵金属-过渡金属-过渡金属氧化物催化剂进行合理设计,构筑金属与金属氧化物双活性中心。结果发现,贵金属负载于过渡金属/过渡金属氧化物(NM-TM/TMO)结构的催化剂在加氢反应中具有优异的催化活性。同时,热处理方法可有效调控催化剂微观结构,并对此构效关系进行了较为深入的研究。
As synergic multiple active sites catalysts can theoretically activate two or more reactant or substrates simultaneously resulting in significantly increase of activity and stability of catalysts, we herein develop a novel catalysts preparation strategy to design and construct noble metal-transition metal-transition metal oxide （NM-TM/TMO） to form bi-active catalytic sites. The experimental results show that such a catalyst has excellent performance in catalytic hydrogenation,e.g. aromatic compounds hydrogenation as the case studies. It was also found that the nanostructure of catalyst can be tunedvia thermal treatments, which are investigated and the relationship between structure and activity is explored to some extent.
