Thermal behavior and catalytic activity in naphthalene destruction of Ce-, Zr- and Mn-containing oxide layers on titanium

► Mn-, Ce- and Zr-containing coatings on titanium as catalyst obtained by plasma electrolytic oxidation. ► Catalysts show activity in naphthalene degradation. ► Ce- and Zr-containing coatings have sufficiently high thermal stability until 850 °C.
