Abstract

P-type tin monoxide (SnO) decorated TiO ₂ nanoparticles have been synthesized by the powder atomic layer deposition (p-ALD) method in a fluidized bed reactor at 150–250 °C. Successful deposition of SnO on a TiO ₂ surface was realized using a precursor combination of Sn(dmamp) ₂ and H ₂ O as Sn source and reactant, respectively. Prepared SnO/TiO ₂ nanoparticles were characterized by XRF, XPS, XRD, and TEM-EDS. Formation of a p-SnO/n-TiO ₂ heterojunction resulted in improved photocatalytic methylene blue degradation performance compared to using a TiO ₂ photocatalyst, which might be attributed to facile separation of photo-induced electron-hole pairs as well as to increased UV/visible light absorption by adopting a narrow bandgap SnO.
