Abstract Graphitische Ablagerungen lösen sich in Ni 0 ‐Nanopartikeln auf, um rezyklierte CH 4 ‐Adsorptionsstellen und oberflächennahe/gelöste C‐Atome bereitzustellen, die zur Ni 0 /ZrO 2 ‐Grenzfläche wandern und eine lokale Zr x C y ‐Bildung induzieren. Die daraus resultierenden sauerstoffarmen karbidischen Phasengrenzflächen unterstützen die Kinetik der CO 2 ‐Aktivierung zu CO(g). Dieser Grenzflächen‐Karbid‐Mechanismus ermöglicht einen verstärkten Übertritt von Kohlenstoff auf den ZrO 2 ‐Träger und stellt einen alternativen Weg der Katalysatorregeneration im Vergleich zum umgekehrten Sauerstoffübertritt auf Ni/CeZr x O y ‐Katalysatoren dar. Er ist daher eher auf Trägern mit begrenzter Sauerstoffspeicher‐ bzw. Austausch‐Kinetik, aber signifikanter karbothermischer Reduzierbarkeit, wahrscheinlich.
