Plasmons can drive chemical reactions by directly exciting intramolecular transitions. However, strong coupling of plasmons to single molecules remains a challenge as ultrasmall mode volumes are required. In the presented work, we propose Cu-Pd plasmonic network metamaterials scalable platforms for plasmon-assisted catalysis. Due absence translational symmetry, these networks provide unique environment featuring large local density optical states and an unparalleled hotspots that effectively localizes light in V < 8 × 10-24 m3. Catalytic performance tests during CO2 conversion reveal production rates up 4.3 102 mmol g-1 h-1 altered reaction selectivity under illumination. Importantly, show catalytic process be tuned modifying network's composition, offering versatile approach optimize pathways.

Direct methanation of carbon dioxide (CO2) in coal-fired flue gas presents a promising approach for achieving neutrality without the energy-intensive CO2 capture process. However, traditional Ni-based catalysts are easily deactivated by sulfur poisoning. In this study, sulfur-tolerant Ni/γ-Al2O3 catalyst with Fe modification (xFe–Ni/A) was developed, and promoting mechanisms were elucidated. Experimental results showed that 1Fe–Ni/A exhibited optimal loading maintained good activity presence SO2. It revealed addition facilitated formation Ni–Fe alloy modulated catalyst's surface chemistry, thereby reaction activity. Furthermore, physicochemical SO2 adsorption properties suggested not only functioned as protective agent Ni sites against but also inhibited overall adsorption, resulting enhanced resistance. This study provides valuable guidance design doping sacrificial modulating using non-noble metals, laying foundation scale-up industrial applications utilization SO2-containing environment.
