丙烯选择氧化制丙烯醛是化学工业中的一个重要反应，在过去的几十年中得到了广泛的研究。今天，光谱，计算和合成方法允许在基本水平上重新审视这个已建立和充分理解的催化过程。因此，最近提出了一个修正的机理路径的选择性丙烯氧化铋的钛酸盐。此外，关于特定表面实体的局部相互作用以及来自半导体科学的概念的研究为描述氧化催化剂的操作模式提供了有价值的信息。新的合成方法不仅可以用于调整催化剂的比表面积和表面物种，而且可以直接获得不同的金属氧化物相或特定的结晶相，在纳米尺度上具有协同作用。由于复杂的多组分体系具有较高的选择性和活性，
The selective oxidation of propylene to acrolein is an important reaction in the chemical industry which has been extensively studied over the last few decades. Today, spectroscopic, computational, and synthetic approaches allow a renewed view of this established and well-understood catalytic process at a fundamental level. Consequently, a revised mechanistic pathway for the selective propylene oxidation over bismuth molybdates has been suggested recently. Furthermore, studies concerning the local interaction of specific surface entities as well as concepts from semiconductor science have provided valuable information to describe the operation mode of oxidation catalysts. New synthetic methods can be used not only to tune the specific surface area and surface species of a catalyst but also to give direct access to distinct metal oxide phases or specific crystalline phases with a synergetic interplay on the nanoscale. Since complex multicomponent systems, which exhibit both higher selectivity and activity ...
