Confining Copper Oxide Nanoparticles within a Metal–Organic Framework for Selective Photocatalytic CO 2 Reduction to Methane

Key Points

• The aim is to enhance photocatalytic CO2 reduction to methane by stabilizing copper oxide nanoparticles within a metal-organic framework.
• Synthesis of a zinc-based metal-organic framework, FICN-13, with specific ligands to encapsulate copper oxide nanoparticles.
• Evaluation of the photocatalytic activity in CO2 reduction experiments.
• Significant improvement in methane yield compared to unsupported copper oxide, demonstrating enhanced catalytic performance.
• Optimized conditions led to a notable increase in selectivity for methane production from CO2.
