Pyrite-enhanced methylene blue degradation in non-thermal plasma water treatment reactor

Degradation of methylene blue using double-chamber dielectric barrier discharge reactor under different carrier gases

“…One route for MB degradation entailed hydroxylation (Benetoli, 2012). Here the MB molecules are attacked by ·OH to form polyhydroxy compounds, such as 3-i and 3-j (Table 2), and aromatic rings of MB were opened to form aliphatics as a result of continuous hydroxylation.…”

“…Furthermore, 99.98% of MB was removed by reactor 1 with an O 2 plasma reacted for 20 min. It is apparent that the performance of the oxygen plasma was superior in reactor 1.The reactor 3(Benetoli, 2011;Benetoli, 2012) was a cylinder vessel reactor. A high voltage needle electrode was placed above the aqueous solution surface, and the solution was grounded.…”

Novel reduced graphene oxide wrapped Bi2.38Mo0.81O6 microspheres for highly efficient visible light photocatalysis

“…S4 in Supporting Information) and the stepwise structure of energy levels constructed in Bi 2.38 Mo 0.81 O 6 @RGO composites, as shown in Fig. 10 [51]. Furthermore, the increase in the light absorption with the presence of RGO is also the important factor for the enhanced photocatalytic performance of the composites, which has been confirmed by UV-vis absorption spectra.…”

Mechanism of Versatile Catalytic Activities of Quaternary CuZnFeS Nanocrystals Designed by a Rapid Synthesis Route

“…Analysis of the mass spectrums at various time intervals indicate the degradation of MB (massto-charge ratio, m/z = 284.06) to the products with lower m/z values along with the presence of intermediate MB oxidized products like leucomethylene blue sulfoxide and leucomethylene blue sulfone. [46][47][48][49] To check the effect of capping ligand on the MB degradation, we have compared the catalytic effi ciency of H-CZIS with 3-mercaptopropanoic acid (MPA) capped CZIS NCs (M-CZIS NCs). H-CZIS NCs shows faster rate of degradation in comparison to M-CZIS NCs ( Figure S14, supporting information).…”
