Advanced BIFs with Co, B, N, and S for Electrocatalytic Oxygen Reduction and Oxygen Evolution Reactions

In this work, a new alkaline-stable boron imidazolateframework(BIF-90) was rationally designed and successfully synthesizedby solvothermal reaction. Due to its potential electrocatalytic activesites (Co, B, N, and S) and chemical stabilities, BIF-90 was explored as a bifunctional electrocatalyst toward electrochemicaloxygen reactions, namely, oxygen evolution reaction (OER) and oxygenreduction reaction (ORR). This work will open new avenues toward thedesign of stable, cheap, and more active BIFs as bifunctional catalysts.
