Adopt the titanium sour D ester water solution legal system have of the Na rice TiO2 does the zinc-air battery cathode catalyst. Shoot line Yan to cast light a table method(XRD) and scan an electronic microscope method(SEM) with the X, and deeply shoot an electronic microscope method(TEM) to carry on token to the TiO2 powder sample of making,[1] result enunciation titanium sour D ester water solution method legal system have of TiO2 catalysts is the Rui titanium mineral type structure, grain the path be not the biggest over 50 nms.Adopt cathode very in the meantime to turn curve, the Heng electric potential turn on electricity with the Heng electric current turn on electricity etc. electricity chemistry test means, result detection,The TiO2 has a better electricity catalyst an activity in the alkalescence lie the quality 6 mols/LNaOH, in keeping with do the zinc-air battery cathode catalyst.
