  • Abundant NH3 in China Enhances Atmospheric HONO Production

    2020-3-10High levels of HONO have frequently been observed in Chinese haze periods and underestimated by current models due to some unknown sources and formation mechanisms. Combining lab-chamber simulations and field measurements in Xi’an and Beijing, China, we found that NH3 can significantly promote HONO formation via the reduction–oxidation of SO2 with NO2 in the aqueousCited by: 9

  • High-efficiency electrocatalyst for N2 conversion to NH3

    In this work, Au nanoparticles (NPs) grown on defective WO3−x (Au/WO3−x) show superior electrocatalytic N2 reduction activity under ambient conditions in 0.1 M KOH. At −0.2 V versus the reversible hydrogen electrode (vs. RHE), the Au/WO3−x catalyst achieves a large NH3

  • Sources of gaseous NH3 in urban Beijing from parallel

    2020-12-10Atmospheric gaseous ammonia (NH 3) is the most abundant alkaline gas in the atmosphere while aerosol ammonium (NH 4 +) constitutes a majority of the inorganic cation concentration in total PM 2.5 mass and plays a vital role in severe haze formation. This study tried to shed some light on sources of gaseous NH 3 through integrating the parallel measurements of δ 15 N values in NH 4 + and

  • Ge, Mn-doped CeO2–WO3 catalysts for NH3–SCR of NOx

    2013-3-1The addition of Ge and Mn to CeO 2 –WO 3 catalysts for NH 3 –SCR of NO x was investigated. The effect of calcination temperature and the influence of SO 2 on SCR activity were studied, and heat treatment with H 2 was used to regenerate sulfated catalysts. The results showed that doping with Ge and Mn enhanced the SCR activity of Ce3W2O x (molar ratio of Ce:W = 3:2) at
