ZnO-SnO2 nanofiber-nanowire stem-branch heterostructure material and preparation method thereof and gas sensor containing the material

摘要

The present invention is zinc oxide - tin oxide (ZnO-SnO ₂ ) nanofiber - nanowire stem - two kinds of different structures , their preparation and relates to a gas sensor comprising the auxiliary structure according to the present invention is homogeneous between zinc oxide and tin oxide nanowires, nanofibers stem branches or an oxidation or reducing gas by the heterojunction structure is effective to sense a high sensitivity . ;
