Left: Hydrogen spillover is depicted, wherein TiO2 undergoes transformation into TiOOH under high hydrogen concentration conditions, which promotes hydrogen mobility on the surface and consequently produces conductivity. Right: Under relatively low hydrogen concentration conditions, the strong interaction between Pt and TiO2 leads to the covering of Pt by TiO2. Images courtesy of POSTECH.
