Room temperature CO sensing by polyaniline/Co3O4 nanocomposite

“…[1][2][3][4][5][6] In recent times, nanomaterials such as nanometals and nano-metal oxides have seen extensive usage as sensors in the field of electronics due to their excellent sensitivity as well as selectivity towards a range of analytes such as volatile organic compounds (VOCs), [7][8][9] toxic and inflammable gases, [9][10][11][12][13] and in quartz crystal microbalance sensors.

“…Over the years, nanomaterials have garnered the attention of the scientific community due to their exceptional properties and applicability in diverse fields. [1][2][3][4][5][6] In recent times, nanomaterials such as nanometals and nano-metal oxides have seen extensive usage as sensors in the field of electronics due to their excellent sensitivity as well as selectivity towards a range of analytes such as volatile organic compounds (VOCs), [7][8][9] toxic and inflammable gases, [9][10][11][12][13] and in quartz crystal microbalance sensors. 14 However, most of these nanometal and metal oxide-based sensors suffer from the disadvantage of having temperature-dependent sensitivity, i.e., they require high operating temperatures, which make them impracticable for use in ambient conditions.…”

Fabrication of Mesoporous Titania Nanoparticles with Controlled Porosity and Connectivity for Studying the Photovoltaic Properties in Perovskite Solar Cells

“…Interestingly, PEG exhibits amphiphilic properties and thereby renders its appropriate solubility in both water and polar organic solvents . Upon the addition of PEG, the oxygen in PEG may interact with titanium species on very small TiO 2 nanoparticles via coordination bonds, while the carbon‐based backbone of PEG can also interact with the alkyl chains of incompletely hydrolysed TTIP on the very small TiO 2 nanoparticles via hydrophobic force . Through the two processes, the resulting PEG‐coated/incorporated nanoparticles can further lead to interparticle interaction to assemble/grow into larger nanoparticles of ∼15 nm in size (Figure S2).…”

“…[44][45] Upon the addition of PEG, the oxygen in PEG may interact with titanium species on very small TiO 2 nanoparticles via coordination bonds, while the carbon-based backbone of PEG can also interact with the alkyl chains of incompletely hydrolysed TTIP on the very small TiO 2 nanoparticles via hydrophobic force. [46] Through the two processes, the resulting PEG-coated/incorporated nanoparticles can further lead to interparticle interaction to assemble/grow into larger nanoparticles of~15 nm in size ( Figure S2). As such, amphiphilic PEG-encapsulated TiO 2 nanoparticles are dispersible in both aqueous and organic media.…”

Plasmonic Light Trapping in Titania–Silver Dots Thin Films

“…The final condensation phase occurred after spinning the solution on the supports and subsequent firing at 100 C. The dehydration of the samples led to TiO 2 formation. [35] However, the formation of the TiO 2 matrix and silver NPs occurred after the calcination process. When titanium dioxide was heated to 400 C, electron-hole pairs were formed by transferring electrons to the conduction band from the valence band.…”
