Iron‑chromium mixed metal oxides catalyse the oxidative dehydrogenation of propane using carbon dioxide

The oxidative dehydrogenation of propane to propene using carbon dioxide is an attractive novel synthesis route produce a key platform chemical. We investigated iron-chromia catalysts prepared by sol-gel. mixed oxides showed improved specific surface area and high concentration acid base sites were found be highly active catalysts. Although coking was observed over the catalysts, regeneration restored majority initial activity 5 consecutive cycles. space time yield amongst most Cr-based in literature.
