Special Issue Information

Dear Colleagues,

Covalent organic frameworks (COFs), as a new generation of crystalline porous materials, have opened up exciting avenues in the field of heterogeneous catalysis due to their high surface areas, ordered porosity, and modular structural tunability. Initially composed of metal-free building blocks, COFs have shown potential in various energy-related catalytic reactions, but are often limited by their intrinsic catalytic activity. The recent integration of single-atom catalysts (SACs) into COF scaffolds marks a transformative advance—uniting the precision and designability of COFs with the exceptional atomic utilization and distinct electronic characteristics of isolated metal sites. This Special Issue aims to highlight the latest progress at the interface of COFs and SACs, from synthetic innovations and post-synthetic metalation strategies to the engineering of light-responsive and redox-active units. We particularly welcome submissions focusing on catalytic applications in challenging reactions such as nitrogen reduction, H2 production, and CO2 conversion. Emphasis is placed on the synergistic interactions between framework topology and active site configuration, offering new insights into structure–activity relationships and guiding principles for the rational design of COF-based SACs.

Researchers are invited to contribute original articles, reviews, and perspectives that showcase emerging trends, novel mechanisms, and cutting-edge materials bridging the gap between organic framework chemistry and atomic-scale catalysis.

Electrochemical nitrate reduction to ammonia offers a sustainable route for nitrogen fixation, yet achieving high efficiency and selectivity remains challenging. Here, a Sustainion-enabled Cu/Co tandem catalyst is developed to couple compositional synergy with ionomer-mediated interfacial regulation. The optimized Cu60Co40/Sus/C electrode delivers a Faradaic efficiency of 91.3% and an NH3 yield rate of 2.63 mmol gcat.−1 h−1 at −0.3 V vs. RHE, surpassing Cu-Co/Nafion/C and Cu-Co/C counterparts. Structural analyses confirm that Sustainion prevents nanoparticle aggregation and maintains robust Cu/Co interfaces. Electrochemical and in situ spectroscopic studies reveal that the cationic quaternary ammonium groups of Sustainion electrostatically enrich NO3/NO2 intermediates, facilitating their adsorption and hydrogenation toward NH3 formation. The combined structural stabilization and intermediate modulation enable efficient tandem catalysis between Cu-driven nitrate activation and Co-mediated hydrogenation. This work provides molecular-level insight into ionomer–catalyst interactions and highlights interfacial engineering as a powerful strategy for sustainable ammonia synthesis. Full article
