- •
TiO2 doped with Mo treated at 850 °C in N2:H2 produces Ti3O5, with few T6O and TiO2.
- •
15 wt% Pt on Mo-doped trititanium pentoxide synthesized as carbon-free catalyst.
- •
Interesting RDE activity in acid solution (0.5 M H2SO4, 0.1 M HClO4) toward the ORR.
- •
Excellent stability after accelerated potential cycling test up to 5000 cycles.
