Characterization results show that their grain size is between 21.2 and 23.2 nm, and the grain growth is inhibited with the increase in Ba-doping concentration. The samples are all spherical with a diameter of about 10 μm, and the surface is very rough. By the gas sensing study of the samples, the results show that the La
