title: Novel oxygen storage mechanism based on redox of sulfur in lanthanum oxysulfate/oxysulfide.
abstract: A sulfur redox cycle between La(2)O(2)SO(4)(S(6+)) and La(2)O(2)S(S(2-)) phases was found for the first time to achieve the oxygen storage of 2 mol O(2) mol(-1), which is eight times larger than that of the conventional CeO(2)-ZrO(2) system.
