•Hydrogen production by water splitting to store sustainable energies is promising strategy.•Mn oxides are highly attractive as catalysts for water oxidation in photosynthetic systems.•We consider the role of PtO2 nanoparticles on water-oxidation catalyzed by Mn oxide.
Herein we report a new method to synthesize highly dispersed PtO2 on layered Mn oxide. The compound was characterized by scanning electron microscopy, energy dispersive spectrometry, high-resolution transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and atomic absorption spectroscopy. Then, we investigated the role of PtO2 on the water-oxidizing activity of nanolayered Mn in the presence of cerium (IV) ammonium nitrate as a non-oxo transfer oxidant. The water-oxidizing activities of these composites with other previously reported Mn oxides are compared and also the important factors influencing the water-oxidizing activities of Mn oxides are discussed.
