Efficient degradation of trimethylamine in gas phase by petal-shaped Co-MoS2 catalyst in the photo-electrochemical system

Sustainable and continuous removal of trimethylamine in a bio‐photoelectrochemical reactor using g‐C3N4/TiO2 photocathode with power generation

“…And it is far more efficient than previous reports. 45 Double-cathode PEC-MFC system performance in removal of high-flow TMA gas To assess the PEC-MFC activity, we increased the flow rate of TMA in the double-cathode PEC-MFC system (catalyst dosage of 0.05 g on each cathode). Figure 9(a) indicates that the TMA degradation rate was about 96%, 98% and 70% when the flow rate was 20, 100 and 120 mL min −1 .…”

Ag/AgBr-oxygen enriched g-C3N4 for efficient photocatalytic degradation of trimethylamine

“…The molecular formula of TMA is (CH 3 ) 3 N, obtained by replacing the H on NH 3 with CH 3 , and it is generally released by the decomposition of trimethylamine N -oxide (TMAO). 2–5…”

“… 8 However, these traditional methods have drawbacks, such as poor stability, secondary pollution, and high operation and maintenance costs, which may result in resource wastage. 9 In 2021, Yan 2 used a simple hydrothermal method to deposit Co metal on the surface of MoS 2 , and used external bias voltage in the photoelectric chemical system to separate photogenerated e − /h + pairs, improve the efficiency of photoelectric catalytic degradation of TMA. The limitation of Yan is that the gas-phase pollutants are still converted to the liquid phase for degradation, and the conversion process will have problems such as low gas–liquid mass transfer efficiency.…”

“…The molecular formula of TMA is (CH 3 ) 3 N, obtained by replacing the H on NH 3 with CH 3 , and it is generally released by the decomposition of trimethylamine N-oxide (TMAO). [2][3][4][5] Researchers have adopted many methods to eliminate TMA at low concentrations, including biological treatments, 6 adsorption, 7 and nonthermal plasma. 8 However, these traditional methods have drawbacks, such as poor stability, secondary pollution, and high operation and maintenance costs, which may result in resource wastage.…”
