Journal ArticleDOI
Photocatalytic reaction and degradation of methylene blue on TiO2 nano-sized particles
TL;DR: In this article, a self-made laboratory photocatalytic reactor and the properties of TiO2 nanoparticles are studied by using UV-A light and photodegradation of methylene blue as a water pollutant evaluated until the photocatalyst process optimizes with the process parameters.
Journal ArticleDOI
Room temperature H2S gas sensor based on rather aligned ZnO nanorods with flower-like structures
TL;DR: In this paper, vertically aligned ZnO rods with flower-like structures were grown on quartz substrates through vapor phase transport method and X-ray diffraction analysis and photoluminescence (PL) measurement were performed to determine crystalline structure and defects, respectively.
Journal ArticleDOI
Sensitive and selective room temperature H2S gas sensor based on Au sensitized vertical ZnO nanorods with flower-like structures
TL;DR: In this article, partial ordered arrays of ZnO nanorods with flower-like structures are introduced for gas sensing applications, and room temperature H2S response of the grown structure shows significant enhancement after modification with Au nanoparticles.
Journal ArticleDOI
The correlation between the substrate temperature and morphological ZnO nanostructures for H2S gas sensors
A. Mortezaali,R. Moradi +1 more
TL;DR: In this article, different ZnO nanostructures are prepared by carbothermal evaporation method on quartz substrates at various deposition temperatures, and the effect of temperature, by keeping constant other parameters, on growth and morphological surface are investigated.
Journal ArticleDOI
Thickness effect of nanostructured ZnO thin films prepared by spray method on structural, morphological and optical properties
TL;DR: In this paper, two different growth modes as a function of spray time were determined: lateral and vertical growth modes which were illustrated schematically, considering with structure and surface roughness.
