Abstract

This work introduces a sustainable and versatile synthesis platform for nanosized metal–ceria catalysts with tunable composition, directly relevant to renewable energy conversion and CO2 utilization. The method enables parallel preparation of multiple catalysts in a single batch with high yield and reproducibility, while reducing environmental impact by 92% compared to conventional approaches, as demonstrated by life cycle assessment (LCA). Its general applicability is confirmed through the synthesis of CeO2, Co–CeO2, and Ni–CeO2 nanomaterials with consistent structural and textural properties. Focusing on CO2 methanation as a benchmark power-to-gas reaction, Ni–CeO2... (More)

This work introduces a sustainable and versatile synthesis platform for nanosized metal–ceria catalysts with tunable composition, directly relevant to renewable energy conversion and CO2 utilization. The method enables parallel preparation of multiple catalysts in a single batch with high yield and reproducibility, while reducing environmental impact by 92% compared to conventional approaches, as demonstrated by life cycle assessment (LCA). Its general applicability is confirmed through the synthesis of CeO2, Co–CeO2, and Ni–CeO2 nanomaterials with consistent structural and textural properties. Focusing on CO2 methanation as a benchmark power-to-gas reaction, Ni–CeO2 catalysts with different Ni loadings achieved CO2 conversions of up to 90% with nearly 100% CH4 selectivity, competitive with state-of-the-art systems. Operando APXPS revealed that Ni–O–Ce interfacial species and surface carbonates are key to balancing conversion and selectivity, providing fundamental insight into CO2 activation pathways. Beyond catalytic performance, the environmentally friendly synthesis strategy aligns with net-zero energy goals by combining efficiency, scalability, and reduced resource intensity. Overall, the study establishes a sustainable nanomaterials platform for energy conversion and storage processes, bridging materials innovation with system-level sustainability.
