Microenvironment Modulation of Cu3-based Metal-Covalent Organic Frameworks via Methyl Substitution for Enhanced Photocatalytic CO2 Reduction to CH4.
Photocatalytic CO2 reduction offers a compelling strategy for carbon neutrality, yet its efficiency is critically limited by both inefficient charge utilization and insufficient active-site modulation. In this study, a methyl-functionalized trinuclear copper building unit was introduced to successfully construct Me2-Cu...
