Formation processes of nitrogen-containing organic compounds from heterogeneous reactions of C3H6/NO2/O3 with α-Fe2O3 particles

Nitrate formation and iron dissolution in the heterogeneous reactions of NH3 on nano α-Fe2O3

“…In some previous studies, this characteristic peak was also attributed to NO 3 − or HNO 3 . 19,47–49 In addition, IC was used to quantify NO 3 − . In IC determination, we also observed the formation of NO 3 − , and the results are shown in Fig.…”

“…In some previous studies, this characteristic peak was also attributed to NO 3 − or HNO 3 . 19,[47][48][49] In addition, IC was used to quantify (from 1.58 mg L −1 to 3.03 mg L −1 ). In the presence of SO 2 , there is formation of NO 3 − (1.50 mg L −1 ) in the dark reaction, demonstrating the oxidation of NH 3 .…”

The heterogeneous reactions of toluene/O3/NH3 on hematite nanoparticles: the impact of light illumination on organic ammonium salt formation

“…26 In previous studies, O 3 could significantly accelerate the heterogeneous reactions of VOCs with inorganic nitrogenous gases and promote the formation of NOCs. 17,27 These indicated that the oxidation of O 3 plays a key role during the heterogeneous reactions of NOCs.…”
