Developing an electrocatalyst platform that can control the interplay among activity, selectivity, and stability at atomic precision remains a grand challenge. Here, we have synthesized highly crystalline polymetallophthalocyanines (pMPcs, M = Fe, Co, Ni, Cu) through annulation of tetracyanobenzene in presence transition metals. The conjugated, conductive, stable backbones with precisely installed metal sites render pMPcs unique electrochemical catalysis, where tunability emerges from long-range interactions. construction pCoNiPc Co Ni dual-site integrates advantageous features pCoPc pNiPc electrocatalytic CO2 reduction electronic communication unprecedented long separation ≥14 chemical bonds. This integration provides excellent activity (current density, j -16.0 -100 mA cm-2 H-type flow cell, respectively), selectivity (CO Faraday efficiency, FECO 94%), (>10 h), making it one best-performing reticular materials.

Hydrogen spillover phenomenon of metal-supported electrocatalysts can significantly impact their activity in hydrogen evolution reaction (HER). However, design active faces grand challenges due to the insufficient understandings on how overcome this thermodynamically and kinetically adverse process. Here we theoretically profile that interfacial charge accumulation induces by large work function difference between metal support (∆Φ) sequentially strong proton adsorption construct a high energy barrier for transfer. Theoretical simulations control experiments rationalize small ∆Φ dilution relocation, thereby weakening enabling efficient HER. Experimentally, series Pt alloys-CoP catalysts with tailorable show ∆Φ-dependent HER activity, which PtIr/CoP smallest = 0.02 eV delivers best performance. These findings have conclusively identified as criterion guiding spillover-based binary electrocatalysts.

Current energy and environmental challenges demand the development design of multifunctional porous materials with tunable properties for catalysis, water purification, conversion storage. Because their amenability to de novo reticular chemistry, metal-organic frameworks (MOFs) have become key in this area.
