Abstract
Metal-organic frameworks (MOFs) are among the most explored porous inorganic materials, showing high surface area, chemical/thermal stability, and functionalizable pores and are applied in several fields of research, especially as catalysts. Zeolitic imidazolate framework-67 (ZIF-67) is a notable cobalt-based MOF structure, receiving special attention due to its easy obtainability with high-dimensional and morphological control, applied in several fields of research such as catalysis, adsorption, and separation. Since last decade, ZIF-67 has been used as a template to synthesize cobalt-based nanostructured materials such as metal nanoparticles, nitrogen-doped porous carbon and, especially, metal oxide nanoparticles, through calcination under controlled temperatures and atmosphere. These ZIF-67 derivatives have been used as electrocatalysts for the oxygen evolution reaction (OER) with high performance. In this context, this chapter will focus on the state-of-the-art synthesis of cobalt oxide and metal-doped cobaltite nanoparticles derived from ZIF-67 and their applicability of these materials as electrocatalysts for OER.
