One-pot synthesis of Na+-free Cu-SSZ-13 and its application in the NH3–SCR reaction†
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.
