The improvement of photocatalytic activity of BaTi O to overall H O splitting was investigated. From the evaluation of co-catalysts, Rh Cr O was preferable. However, this co-catalyst was degrading with the progress of the photocatalytic reaction. When CoO was co-loaded as the co-catalyst for O evolution reaction over the surface, the steady progress of the photocatalytic reaction can be confirmed. Here, effective way and condition for loading CoO co-catalyst as well as effective preparation method of BaTi O were demonstrated in order to improve the photocatalytic activity of BaTi O with Rh Cr O and CoO co-catalysts to the overall H O splitting. As the results, the photocatalyst prepared by preferable method and condition showed high photocatalytic activity to the overall H O splitting, where the apparent quantum yield (AQY) at 313 nm reached to 41 %. 4 9 2 0.7 1.3 3 x 2 x 4 9 4 9 0.7 1.3 3 x 2 2
