Abstract:Biodiesel is an environmentally friendly fuel that may partially replace petroleum diesel in transportation. One possible disadvantage of biodiesel is that alkali and alkaline earth metals can significantly affect Cu speciation and the elemental composition of copper chabazite (Cu-CHA) catalysts used in vehicle emission control units. To investigate this, we perform atomic-scale characterization of Cu-SSZ-13 zeolites contaminated by Mg, K, and Na using inductively coupled plasma-optical emission spectroscopy a… Show more
