HOT Article: The role of carbide surface morphology on olefin metathesis reactivity

An increased industrial demand for propene, and potential applications in the processing of renewable raw materials has led to a strong renewal of interest in development of
heterogeneous olefin metathesis catalysis. Olefin metathesis proceeds through the formation of metal carbene initiating and propagating species. On contact with the reactant, catalyst precursors generate metal carbene initiating sites.  Active polycrystalline molybdenum carbide foils may be prepared through carbonyl bond breaking in chemisorbed aldehydes and ketones to yield surface alkylidene and oxo groups.  In this HOT article, helium ion microscopy imaging is used to characterize the foil as a first step towards determining if the carbide structure plays an important role in the olefin metathesis related surface chemistry.

    Organized content is the best way to display or post an article, thank you for making it easy to digest your post.

  2. Once you find a niche, start filling the idea. Build a take no prisoners website and the people what they “want” not what you “think” they require. Think about this. All we humans buy or do existence is as it is sapui5 something we want, we don’t really are interested. Right? Of course.
