Our achievements in this work follow:
(1) Observed the existence of one type of two-dimensional defect (Ruddlesden-Popper fault) at the surfaces of LaFeO3;
(2) Designed synthesis methods to controll the density of the surface defects;
(3) Discovered their enhancing effect on the reduction of toxic CO into nontoxic CO2;
(4) Proposed two novel catalysis-cycle loops for such reduction reaction;
(5) Revealed the microscopic mechanism underlying the remarkable reduction effect of surface defect by analyzing the electronic structures in depth.
