文摘

MnOx were electrodeposited over Ti and TiO2-NTs for the electro-oxidation of phenol. Different oxidation states of the manganese and MnOx crystalline phases were obtained. α-MnO2 was the most active phase, while α-Mn2O3 was the most stable one. TiO2-NTs contribute to increase surface area and stability and to reduce the working potential. Energy related conversions have pointed out a promising performance of the MnOx for this application.
