The Influence of Si/Al Ratios on Adsorption and Desorption Characterizations of Pd/Beta Served as Cold-Start Catalysts
The majority of NO<sub>x</sub> is exhausted during the cold-start period for the low temperature of vehicle emissions, which can be solved by using Pd/zeolite catalysts to trap NO<sub>x</sub> at low temperature and release NO<sub>x</sub> at a high temperature that...
