Titania Nanotubes Grown on Carbon Fibers for Photocatalytic Decomposition of Gas-Phase Aromatic Pollutants
This study aimed to prepare titania (TiO₂) nanotube (TNT) arrays grown on un-activated carbon fibers (UCFs), with the application of different TiO₂ loadings based on the coating-hydrothermal process, and to evaluate their photocatalytic activity for the degradation of sub-ppm levels of aromatic pollutants (benzene, toluene, ethyl benzene, and o-xylene (BTEX)) using a plug-flow photocatalytic re...
متن کاملNanotubes and Nanorods on CMOS Substrates for Gas Sensing
In this paper we discuss the combined use of integrated CMOS microhotplates employing nanomaterial sensing layers for intelligent, compact gas sensors with increased sensitivity, selecitivity and fast response times. We first review the status of nanomaterial-based gas sensors, their operating principles, discussing growth issues and their compatbility with CMOS substrates. We then describe Mul...
متن کاملInteraction of water with titania: implications for high-temperature gas sensing.
High-temperature gas sensors based on semiconducting metal oxides show potential for optimization of combustion processes, resulting in efficient energy use and minimization of emissions. Such metal oxides can function as gas sensors because of the reaction of the sensing gas (e.g., CO) with ionosorbed oxygen species on the oxide surface with the resulting increase in conductivity. A limitation...
متن کاملGas sensing with gold-decorated vertically aligned carbon nanotubes
Vertically aligned carbon nanotubes of different lengths (150, 300, 500 µm) synthesized by thermal chemical vapor deposition and decorated with gold nanoparticles were investigated as gas sensitive materials for detecting nitrogen dioxide (NO2) at room temperature. Gold nanoparticles of about 6 nm in diameter were sputtered on the top surface of the carbon nanotube forests to enhance the sensit...
متن کاملTiO2 Nanotubes: Recent Advances in Synthesis and Gas Sensing Properties
Synthesis--particularly by electrochemical anodization-, growth mechanism and chemical sensing properties of pure, doped and mixed titania tubular arrays are reviewed. The first part deals on how anodization parameters affect the size, shape and morphology of titania nanotubes. In the second part fabrication of sensing devices based on titania nanotubes is presented, together with their most no...
