In-situ surface reconstruction of Co-based imidazole zeolite framework by Mo etching for superior water oxidation

Although zeolitic imidazolate frameworks (ZIFs) possess the merits of orderly porosity, high permeability, and easy functionalization, the transformation of ZIFs into the real active species and the promotion of the catalytic efficiency and stability are still challenging. Herein, CoMo-based three-dimensional (3D) hollow nanocages composed of interconnected nanosheets are fabricated by in-situ etching metal-organic framework (ZIF-67) under the aid of MoO
