WebJan 10, 2024 · In this work, the photocatalytic conversion of nitrobenzene (NB) to aniline (AN) was studied. The photocatalytic reaction was performed using commercial TiO 2 (P25) and a photocatalytic aerogel, based on P25 embedded in syndiotactic polystyrene (sPS) aerogel (sPS/P25 aerogel) as photocatalysts. Different alcohols were used as hydrogen … WebMar 1, 2016 · The reactor effluent is virtually free of nitrobenzene due to the high conversion of the reaction.
