DyMnO: Synthesis, Characterization and Evaluation of Its Photocatalytic Activity in the Visible Spectrum.

DyMnO is a p-type semiconductor oxide with two crystal systems, orthorhombic and hexagonal. This material highlights its ferroelectric and ferromagnetic properties, which have been the subject of numerous studies. Nevertheless, its photocatalytic activity has been less explored.

Determining the Photoelectrical Behavior and Photocatalytic Activity of an h-YMnO New Type of Obelisk-like Perovskite in the Degradation of Malachite Green Dye.

YMnO is a P-type semiconductor with a perovskite-type structure (ABO). It presents two crystalline systems: rhombohedral and hexagonal, the latter being the most stable and studied. In the hexagonal system, Mn ions are coordinated by five oxygen ions forming a trigonal bipyramid, and the Y ions are coordinated by five oxygen ions.
