摘要: Emission regulations for diesel cars are becoming stricter, especially NOx emissions. Various devices available abatement such as NSCR, EGR, SCR, LNT, etc. But none of the methods is equivocally accepted 100% reduction from exhaust. SCR a potential method to convert N2 by reductant under rich-O2 Different types catalysts including noble metals, zeolite, spinels, hydrotalcite, metal oxides, found effective strict conditions diverse reductants (NH3/urea/HC/H2, etc.) NOx. catalyst-reductant combination came up be limitation free. Therefore, present paper aimed develop total environmental friendly achieve emission standard and leanburn gasoline vehicles at low temperature combining altogether novel approach. The approach involves H2HC-SCR lean over nano-size Ag/Al2O3 green catalyst using LPG reductant. was chosen reducing agent it leads strong decrease in Gibbs free energy values NO N2. were characterized N2-sorption, XRD, FTIR SEM. best among prepared showed
