Gold Nanoparticle Embedded Titanium Dioxide Thin Film for Surface Plasmon Resonance Gas Sensing at Room Temperature
The optical gas sensing properties of gold (Au) nanoparticles (NPs) doped into titanium dioxide (TiO2 matrix prepared by sol–gel method and annealed at different temperatures have been investigated. AFM images reveal that the Au NPs are exuded from the film during annealing. The chemical interaction of the hydrogen (H2 and carbon monoxide (CO) molecules on the Au surface will increase the overa...
متن کاملA Facile Approach of Thin Film Coating Consisted of Hydrophobic Titanium Dioxide over Polypropylene Membrane for Membrane Distillation
In this work, the hydrophobic modification of TiO2 nanoparticles (HTiO2) was carried out by reacting with dodecylphosphonic acid (DDPA) and hexylamine solution. A facile approach of the self-assembly technique was used for the coating of hydrophobic HTiO2 layer over the microporous polypropylene (PP) membrane. The self-assembled layer was formed between the interface of trimesoyl chloride (TMC)...
متن کاملZnO:Al Thin Film Gas Sensor for Detection of Ethanol Vapor
The ZnO:Al thin films were prepared by RF magnetron sputtering on Si substrate using Pt as interdigitated electrodes. The structure was characterized by XRD and SEM analyses, and the ethanol vapor gas sensing as well as electrical properties have been investigated and discussed. The gas sensing results show that the sensitivity for detecting 400 ppm ethanol vapor was ~20 at an operating tempera...
متن کاملTiO2 thin film gas sensor for monitoring ammonia
Systematic development and mechanistic studies of sensing materials are critical to the design of higher performance gas sensing elements and arrays. Polycrystalline metal-oxide semiconductors such as SnO2 and TiO2 are among the most widely used materials for thin film-based conductometric gas sensors. The mechanistic steps responsible for the gas-induced conductance changes of polycrystalline ...
متن کاملMicromachined thin-film gas flow sensor for microchemical reactors
As microchemical systems (MCS) have gained in importance since their introduction in the last decade, it has become recognized that appropriate sensing and control capabilities are needed if MCS are to reach their potential. In this context, we present a study of the working behavior of a novel thin-film micro flow sensor which is integrated with a silicon microreactor with a submillimeter chan...
