In literature TiO2 is giving less than 1% H2 Production under UV light and P-25 is the benchmark for photocatalysts without loading any cocatalyst that synergic effect of rutile and anatase phase plays an important role for charge separation but after loading cocatalysts Pure anatase is giving more yield than P-25 than at that place how can explain the things are change is that Rutile which is loaded with cocatalyst  like pd, Pt will not effective  as  pure anatase  is effective part should not give effective H2 Production or what kind of interaction is possible??
