under various acid types (HCl, H2SO4, and HNO3) and acid/CFA ratios (5–25 mLacid/gCFA). High product purity (up to 97%) was achieved with HCl (20%wt), and acid/CFA ratio of 20 mLHCl/gCFA. The treated CFA was then converted to zeolite by the fusion reaction under various Si/...
For instance, Ru metal in acid media loses most of its activity after the first cycle of reaction and completely dissolves within the first 10 cycles, due to metal oxidation when the potential rises42. RuO2 also presents high OER activity but suffers from corrosion after the first cycle; it...
The sticking coefficient of N2O5 on NaCl aerosol α=0.032±0.003 is determined at 292.3±0.5K and various relative humidities, considering the decrease of the aerosol diameter during the reaction. The rate constant ratio for the consecutive chemical reaction leading to ClNO2 (a) or 2 HNO3 (b...
After 30 min, a new absorbance peak at 213 nm appeared and its intensity increased with increasing the reaction time, suggesting the production of a new kind of intermediates dur- ing the reaction31. However, if N2 instead of air was used, a totally different evolution of the UV-Vis ...
