Electrocatalytic H2O2 production via two-electron O2 reduction by Mo-doped TiO2 nanocrystallines

Mo acts as an effective dopant to boost the catalytic activity of TiO 2 for the 2e − O 2 reduction reaction. Such Mo–TiO 2 electrocatalyst achieves a high Faradaic efficiency of 92% and a large H 2 O 2 yield of 395.3 mmol g cat −1 h −1 in alkaline medium.
