Heterostructures of TiO2@Fe2O3 with a specific electronic structure and morphology enable us to control the interfacial charge transport necessary for their efficient photocatalytic performance. In spite extensive research, there still remains profound ambiguity as far band alignment at interface is concerned. this work, extended type I heterojunction between anatase TiO2 nanocrystals α-Fe2O3 hematite nanograins proposed. Experimental evidence supporting conclusion based on direct...
The paper deals with application of three nanomaterial systems: undoped TiO2, chromium-doped TiO2:Cr and TiO2-SnO2 synthesized by flame spray synthesis (FSS) technique for hydrogen sensing. emphasis is put on the role anatase rutile polymorphic forms TiO2 in enhancing sensitivity towards reducing gases. Anatase-to-rutile transformation achieved annealing air at 700 °C, specific Cr doping modification SnO2. Undoped exhibit n-type behaviour while TiO2: 5 at.% a p-type semiconductor. X-ray...
Titanium oxide thin films were deposited by rf magnetron sputtering of Ti metallic target in flow-controlled O2 + Ar atmosphere. Comprehensive investigations crystallographic structure, phase composition, morphology and optical properties performed means X-ray diffraction, reflectivity (XRR), scanning electron microscopy, spectrophotometry, photoemission spectroscopy. It was found that as the O2/(O2 Ar) flow ratio increased, microstructure changed from TiO, Ti2O3, to rutile TiO2,...
