| abstract |
The invention discloses a production method for nanofibers of metal oxide, wherein the metal oxide is a metal oxide of at least one metal selected from Sc, Y, La, Ce, Pr, Nd, Sm, Gd, Dy, Ho, Yb, Zr, Sr, Ba, Mn, Fe, Co, Ma and Ga, comprising: a) spinning a compound precursor containing a salt of the metal, to produce nanofibers of the precursor containing the metal oxide; and b) calcining the nanofibers of the precursor containing the salt of the metal at a temperature in a range of from 500°C to 800°C, to obtain nanofibers of metal oxide containing the at least one metal element. The invention further discloses nanofibers of metal oxide, a solid electrolyte material, a fuel cell and an oxygen sensor. |
