Synthetic strategy for metallophthalocyanine covalent organic frameworks for electrochemical water oxidation

Atomically dispersed metal catalysts are interesting materials for electrocatalysis. To this end, covalent organic frameworks (COFs) offer an excellent opportunity the periodic placement of catalytically active single atoms within a porous framework. We report here synthetic strategy to series imide-linked metal-containing phthalocyanine (Pc) COFs with different contents. Electrocatalytic activity towards oxygen evolution reaction was studied under alkaline conditions and COF prepared from NiPc showed best performance current density j = 10 mA cm?2 being reached at overpotential ?10 ? 410 mV Tafel slope b 75 mV/dec. In addition, material long-term stability during testing time 100 h.
