This study proposed an efficient C,N codoped TiO 2 electrode toward water oxidation to selectively produce H 2O 2 in the acidic electrolyte, which could be further used to in situ generate H 2O 2 for the energy- and environment-related fields with water as the precursor.
More importantly, a simple recalcination strategy was developed to recover the deactivation electrode. Under the optimal applied potential, the cumulative H 2O 2 concentration for this sample reached 0.29 μmol L –1 cm –2 h –1. The calcination temperature and urea atmosphere were found to play key roles in its catalytic performances the optimized 600N sample exhibited an onset potential of 2.66 V (vs Ag/AgCl) and a Tafel slope of 51 mV dec –1 at pH 3. An electrochemical anodic oxidation method combined with postcalcination in the presence of urea was applied to fabricate such a C,N codoped TiO 2 electrode, which was evidenced by detail structural characterizations. In this work, for the first time, we reported a C,N codoped TiO 2 electrode for selective electrocatalytic water oxidation to produce H 2O 2 in an acidic electrolyte. Production of hydrogen peroxide (H 2O 2) via in situ electrochemical water oxidation possesses great potential applications in the energy and environment fields.
