Optimization synthesis of carbon nanotubes-anatase TiO2 composite photocatalyst by response surface methodology for photocatalytic degradation of gaseous styrene

Pollution profiles, health risk of VOCs and biohazards emitted from municipal solid waste transfer station and elimination by an integrated biological-photocatalytic flow system: A pilot-scale investigation

“…Few substances are still unable to be biologically degraded, although this technology is relatively cheap and reliable process. On the other hand, photocatalytic (PC) technology can generate powerful but not selective oxidant species, such as holes and active oxygen species, which can not only readily oxidize a wide spectrum of organic gas [14][15][16], but also inactivate the pathogens effectively [17][18][19]. Nevertheless, there are several scenarios that make them economically disadvantageous.…”

Synthesis of TiO2 hollow sphere multimer photocatalyst by etching titanium plate and its application to the photocatalytic decomposition of gaseous styrene

“…The adsorption ability and photocatalytic activity of the prepared photocatalysts were evaluated using gaseous styrene (initial concentration of 15 ± 1 ppmv) as a model volatile organic compound (VOC) in a continuous flow mode [27]. And the diagram of the experimental set-up is shown in Fig.…”

Anatase TiO2 mesocrystals with exposed (001) surface for enhanced photocatalytic decomposition capability toward gaseous styrene

“…The adsorption capability and photocatalytic activity of the prepared samples were tested by the adsorption and degradation of gaseous styrene with an initial concentration of 15 ± 1 ppmv operating in a same continuous flow-through mode as reported in our previous works [6,27,28]. In a typical experimental process, 0.10 g sample as photocatalyst was loaded in a cubic quartz glass reactor with a volume of 1.0 cm × 1.0 cm × 0.5 cm.…”
