Dual-ion doping: Through theoretical and experimental methods, we determined that dual-doped TiO2 has a much higher electron conductivity than that of single-doped TiO2, and more Pt occupies the defect sites of dual-doped TiO2. Pt on this dual-doped support is almost three times more active than Pt on single-doped TiO2 and is more stable than Pt on carbon.
