Background:

• Electrocatalytic reduction of carbon dioxide (CO2RR) is crucial for mitigating greenhouse gas emissions.
• Two-dimensional (2D) organic framework materials, including 2D-MOFs and 2D-COFs, show great potential as catalysts due to their unique properties.

Purpose of the Study:

• To systematically review recent advancements in 2D organic framework materials for CO2RR.
• To categorize CO2RR by target products: carbon monoxide, methane, formic acid, and multi-carbon compounds.
• To critically evaluate design strategies impacting catalyst performance.

Main Methods:

• Literature review of recent research on 2D organic frameworks for CO2RR.
• Categorization of studies based on target products of CO2RR.
• Analysis of structure-activity relationships and design strategies.

Main Results:

• 2D organic frameworks offer high surface area, tunable structures, and accessible active sites for CO2RR.
• Key design strategies include metal center engineering, ligand modification, layer tuning, and system optimization.
• Performance is evaluated based on activity, selectivity, and stability for various products.

Conclusions:

• Despite significant progress, challenges remain in long-term stability, low-concentration CO2 operation, and cost-effectiveness.
• Future research should focus on self-healing materials, composites, and machine learning for industrial CO2RR applications.
