Spinel cobalt-based binary metal oxides as emerging materials for energy harvesting devices: synthesis, characterization and synchrotron radiation-enabled investigation.

ABSTRACT: The synthesis and characterization of spinel cobalt-based metal oxides (MCo₂O₄) with varying 3d-transition metal ions (Ni, Fe, Cu, and Zn) were explored using a hydrothermal process (140 °C for two hours) to be used as alternative counter electrodes for Pt-free dye-sensitized solar cells (DSSCs). Scanning electron microscopy (SEM) and atomic force microscopy (AFM) revealed distinct morphologies for each metal oxide, such as NiCo₂O₄ nanosheets, Cu Co₂O₄ nanoleaves, Fe Co₂O₄ diamond-like, and Zn Co₂O₄ hexagonal-like structures. The X-ray diffraction analysis confirmed the cubic spinel structure for the prepared MCo₂O₄ films. The functional groups of MCo₂
