Impact of Structure on the Catalytic Performance","description":"\u003cp\u003eThe potential of a new catalyst class based on vanadium containing oxynitrides has been explored in the ammoxidation of 3-picoline (3-PIC) to 3-cyanopyridine (3-CP). So far, mixed oxides of the type SbVTiSiO belong to the best catalysts for this reaction, however, space-time yields (STY) did not exceed 150 g\/lh. Improving STY while maintaining high 3-CP selectivity would be energetically most sustainable. Therefore, ternary VAlZrON and VZrPON, binary VMoON and VSbON oxynitrides as well as VMON\/MoxOyNz (M = Al or Zr) catalysts have been investigated for their catalytic performance and structure-reactivity relationships. With VZrAlON catalysts, highest STY values ever measured have been obtained, while VSbON catalysts bear a great potential, too. By spectroscopic multimethod analysis, applied ex and in situ, structure-reactivity relationships have been proposed. The presence of direct V-N junctions and anionic surface defects are essential for high nitrile selectivity. This is the best fulfilled for VZrAlON, VMoON and VSbON catalysts.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783954040377\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783954040377","offer_id":40129674510429,"sku":"9783954040377","price":26.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/76b02589-ecd3-4d53-925e-6708d011843f.jpg?v=1756877844","url":"https:\/\/shop.autorenwelt.de\/products\/novel-ammoxidation-catalysts-based-on-vanadium-containing-oxynitrides-impact-of-structure-on-the-catalytic-performance-von-christiane-janke","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
