Abstract

Na+-free Cu-SSZ-13 zeolites have been rationally synthesized via a cooperative strategy, which has the advantages of rapid crystallization (9-48 h), high yield (86-94%) and adjustable Cu content. The NH3-SCR catalytic performance and hydrothermal stability of the calcined materials were studied and correlated with their physicochemical properties.
