Acceleration of Trimethylamine Removal Process Under Synergistic Effect of Photocatalytic Oxidation and Surface Discharge Plasma Reactor

Abstract

Removal of trimethylamine (TMA) from the air is experimentally investigated by combining photocatalysis with a DBD plasma reactor, at ambient temperature and atmospheric pressure. Many parameters are investigated in this work, such as flowrate, inlet concentration, relative humidity of effluent, and specific energy of discharge. By combining non‐thermal plasma and photocatalysis, a synergy effect on the removal efficiency of TMA has been observed under different experimental conditions. Moreover, we note that adding a photocatalyst in the zone of plasma inhibits ozone formation. The formation of by‐products due to TMA removal is also studied. The identified and analyzed by‐products are classified into four groups: intermediary products, carbon monoxide, carbon dioxide, and ozone and nitrogen oxides.

Synthesis and Characterization of TiO2 Nanotubes (TiO2-NTs) with Ag Silver Nanoparticles (Ag-NPs): Photocatalytic Performance for Wastewater Treatment under Visible Light

“…Nanostructured TiO 2 has also been used in many applications such as sensors [12], photocatalysis [13][14][15][16], and solar energy conversion [17]. TiO 2 nanotubes have attracted particular attention because of their high specific surface area [18], high photoactivity [19], and the rapid transfer rate of holes and electron-hole pairs (e − /h + ) photogenerated along the nanotubes [20][21][22]. However, two major factors limit the performance of TiO 2 .…”

“…On the other hand, the photogenerated (e − /h + ) pairs exhibit a high rate of recombination due to a high density of crystal defects [23]. To overcome these problems, many strategies have been established, such as doping TiO 2 (metallic or non-metallic dopants) [13,17] and coupling with other semiconductors [19,20,24], which could expand absorption under visible light and improve the lifetime of the photogenerated (e − /h + ) pairs. Recently, it has been shown that the decoration of TiO 2 nanotubes with noble metal nanoparticles can increase their absorption in the visible range, thanks to the surface plasmon resonance (SPR) [25] induced in the metallic nanoparticles in the presence of a light wave.…”
