Abstract Die Umwandlung von Methan in Alkohole unter milden Reaktionsbedingungen ist eine vielversprechende Technologie für die Nutzung abgelegener Methanvorkommen. Die flüssigen Alkohole können in Pipelines transportiert und zu wertvolleren Chemikalien weiterverarbeitet werden. Hier wird gezeigt, dass ein Katalysator aus Nickeloxidpartikeln auf einen Ceroxid‐Zirconiumoxid‐Träger (NiO/CZ) Methan in einem einzigen, kontinuierlich betriebenen Reaktor zu Methanol und Ethanol umwandeln kann. Die Reaktion geschieht bei milden Temperaturen (723 K) mit O 2 als Oxidationsmittel. Die Produktion von Alkoholen erfordert die Gegenwart von Wasserdampf, um die vollständige Oxidation zu CO 2 zu unterdrücken. Die Synergie zwischen Lewis‐aciden NiO‐Partikeln und dem redoxaktiven Ceroxid‐Zirconiumoxid‐Träger ermöglicht die ungewöhnliche Reaktivität dieses Katalysators.
