  "abstract": "Integrated CO₂ capture and methanation (ICCM) provides a direct route for converting captured CO₂ into synthetic methane, but its large-scale implementation is limited by material stability and sustainability. Here, we report NiCeO₂/ionic clay hybrid materials, where the Mg-Al oxide derived from the layered double hydroxide (LDH) clay acts as an adsorbent matrix for NiCeO₂ catalytic nanoparticles. The hybrids exhibit enhanced CO₂ uptake, efficient low-temperature operation (300 °C) with 100% CH₄ selectivity, and excellent cyclic stability under ICCM conditions. Although the NiCeO₂/LDH hybrids show lower methane productivity per unit mass of total material than NiCeO₂ alone, they significantly improve catalyst utilization, producing up to seven times more CH₄ per unit mass of NiCeO₂. Operando XANES reveals a reversible Ni2+/Ni0 redox transition under alternating CO₂/H₂ atmospheres, demonstrating that the active Ni phase dynamically adjusts its oxidation state during CO₂ adsorption–hydrogenation cycles. Life cycle assessment demonstrates a markedly reduced environmental footprint for the hybrid materials compared with NiCeO₂ for the same methane output, highlighting NiCeO₂/LDH hybrids as sustainable and scalable platforms for integrated CO₂ capture and conversion",
