NH2 species and nitrate species were main intermediates participating in NH3-SCO reactions over V0.5/Pt0.04/TiO2 catalyst. The generated NOx would further react with fresh NH3 in an efficient way under the action of VOx species in the upper layer via selective catalytic reduction (SCR) reactions owning to the excellent redox ability of V0.5/Pt0.04/TiO2 catalyst. Copy files from folder Crack to folder where you installed the game 4. Open DNF Duel.zip, next run EXE installer DNF Duel.exe 2. It led to more abundant Pt0 species in the lower layer, which was favorable for oxidizing the diffused NH3 efficiently into N2, H2O and a part of NOx. Instructions for DNF Duel Free Download 1. It was ascribed to a preferable synergistic effect between the upper layer of VOx species and the lower layer of Pt species supported on TiO2. V0.5/Pt0.04/TiO2 catalyst exhibited outstanding NH3-SCO performance, which obtained complete NH3 conversion and 80.2 % of N2 selectivity at 225 ✬. The catalytic performance of Pt-V system significantly depended on the combination mode between VOx and Pt species. Herein the influence of deposition order of V and Pt components on NH3-SCO performance was investigated with constant loadings of 0.5 wt.% V and 0.04 wt.% Pt.
But it is challenging to improve NH3 conversion activity and N2 selectivity, as well as cost-economy. Pt-V bimetallic catalytic system maybe a promising alternative to noble metal catalysts for selective catalytic oxidation (SCO) of NH3.
