Background:

• Metal-organic frameworks (MOFs) are extensively studied as heterogeneous catalysts owing to their structural diversity and excellent properties.
• MOFs show promise as templates for synthesizing conductive and electrochemically active catalysts.
• Conventional methods often require high-temperature annealing, which can degrade MOF structures and active sites.

Purpose of the Study:

• To review recent advancements in MOF-based materials for electrocatalysis.
• To highlight strategies for enhancing conductivity and electrochemical activity in MOFs without post-treatment.
• To discuss the potential of MOF-based composites in electrochemical reactions.

Main Methods:

• Review of literature on MOF-based electrocatalysts.
• Categorization of advanced MOF structures based on conductivity and activity.
• Analysis of strategies including pristine MOFs, MOFs with conductive substrates, and MOF-hybrid materials.

Main Results:
