Excellent NO_x storage properties were realized by adding KNO₃ to Pt/K-titanate nanobelt. Maintaining nanobelt structure and optimizing the amount of KNO₃ added are the key factors to obtaining extremely high NO_x storage capacity. The segregation of K⁺ from and back to the nanobelt wall is NO_x storage and reduction mechanism.
