Highly sensitive and selective butanone sensors based on cerium-doped SnO2 thin films

Morphology transformation of Cu2O sub-microstructures by Sn doping for enhanced photocatalytic properties

“…X-ray photo-electron spectroscopy (XPS) was performed on a Thermo ESCALAB 250XI electron spectrometer equipped with Al K α X-ray radiation (hν =1486.6 eV) as the source for excitation. be ascribed to the increase of the disordered structures and defects induced by Sn doping [25,26,43,44]. The peak at 422 cm -1 and 800 cm -1 were assigned to four-phonon mode 3Γ -12 +Γ -25 and a second order (2) 15 , respectively [24][25][26].…”

Azadirachta indica plant-assisted green synthesis of Mn3O4 nanoparticles: Excellent thermal catalytic performance and chemical sensing behavior

“…Among various sensing materials, metal oxides based sensors have gained a lot of attentions owing to their nanoscale engineering, good electrical, mechanical and chemical stability [20][21][22]. So far, several metal oxides such as cobalt-doped SnO 2 thin films [23], In 2 O 3 nanowires [24] etc.…”

Facile preparation of cerium (Ce) and antimony (Sb) codoped SnO2 for hydrogen production in lactic acid solution

“…When the doping amount of Ce was changed from 2 mol% to 6 mol%, no characteristic peaks from other crystallites were detected. However, the separated phase CeO 2 also existed on the surface of ATO particles besides the partial incorporation of Ce 4 þ ions into the ATO lattice [15]. When the concentration of cerium increased to 6 mol% ( Fig.…”
