Exploration of metal organic frameworks and covalent organic frameworks for energy-related applications

Rahim Shah et al.

Summary: Metal-organic frameworks (MOFs) and covalent-organic frameworks (COFs) have attracted significant attention as highly crystalline advanced permeable materials with large surface area, ordered pores/channels, and controllable structure. However, their low structural stability and electrical conductivities limit their applications in photocatalysis and energy storage/conversion. Extensive research has focused on maximizing their advantages and overcoming these limitations. This review article provides a background and timeline of COF/MOF development, discusses synthetic procedures, recent achievements, and milestones in CO2 reduction, hydrogen production, lithium-ion batteries, and supercapacitors, and explores the challenges and future prospects for high-performance COF/MOF materials in photocatalysis and electrochemical energy storage.

Ladder-type π-conjugated metallophthalocyanine covalent organic frameworks with boosted oxygen reduction reaction activity and durability for zinc-air batteries

Zhen Zhang et al.

Summary: pi-Conjugated two-dimensional covalent organic frameworks (COFs) have emerged as promising oxygen electrocatalysts due to their controllable architectures, excellent electrical conductivity, and highly exposed molecular active sites. In this study, a novel ladder type pi-conjugated two-dimensional benzoimidazobenzophenanthroline-linked iron-phthalocyanine COF (FePc-BBL COF) was synthesized and exhibited exceptional oxygen reduction reaction (ORR) activity and kinetics. The FePc-BBL COF showed a remarkable half-wave potential and a low Tafel slope in alkaline media. Additionally, it demonstrated a high turnover frequency and mass activity, surpassing the performance of Pt/C. When applied as a cathode electrocatalyst for zinc-air batteries, the FePc-BBL COF displayed superior power density, specific capacity, and long-term durability compared to Pt/C. This work provides a promising strategy for designing stable and efficient electrocatalysts for sustainable energy conversion and storage devices.
