Deskripsi
Highlights The acid etching Co-naphthalenedicarboxylic acid-based metal–organic frameworks (donated as AE-CoNDA) catalyst displayed an excellent oxygen evolution reaction (OER) activity for long-term stability. Integration of the AE-CoNDA cocatalyst into BiVO4 achieved a remarkable PEC-OER activity. The stretched Co-O bond length regulated the spin state transition at the Co active sites. The optimized high spin state of Co sites adjusted the orbitals hybridization of Co 3d and O 2p.
