Pt decorated Cu₂O nanocomposite to detect ppb level Ozone concentration

Salman Latif, Jiahao Ni, Ren-Jang Wu, Kaseb D. Alanazi et autres

This study reports the synthesis, characterization, and ozone-sensing performance of platinum (Pt)-decorated cuprous oxide (Cu₂O) nanomaterials at room temperature. Structural and optical analysis confirmed the uniform distribution of Pt nanoparticles (∼4.5 nm) on Cu₂O nanocubes, which effectively reduced the material’s optical bandgap …
