a XRD patterns showing the formation of a tetragonal phase upon the incorporation of Si into SCO. b A schematic depicting the tetragonal crystal structure of Si–SCO. c HRTEM image of Si–SCO and the corresponding FFT pattern with zone axis of [\(1\bar{1}\bar{1}\)]. d HAADF-STEM image of Si–SCO and the corresponding EDS mapping images of Sr, Co, Si and O. Scale bar in c is 5 nm and in d is 200 nm.
