The iron-doped nickel oxide catalysis films were deposited by DC reactively magnetron sputtered apparatus with two face-to-face targets.

The iron-nickel oxide,which has better properties of anticorrosion and activity of oxygen evolution reactive in alkaline solution,is as the catalysis anode of photoelecrochemical hydrogen production using solar cell.

A novel process for preparing nanoic W-Ni-Fe composite oxides;
