TiO2 nanotube array(TNA) was prepared by electrochemically anodizing titanium sheet.Metal manganese was deposited on the surface of TNA by electrochemical reduction to enhance its photoelectrochemical response to visible light.The influences of deposition voltage,time and concentration of Mn(II) ion were investigated by orthogonal test.The results show that the surface modification of manganese on TNA can increase its visible light response,and the photoelectrochemical current is obviously enhanced at a biasing voltage of 0.5 V(vs.SCE).The results from orthogonal test indicate that the deposition time and voltage are the key factors to influence the performance of manganese modified TNA.The optimal conditions for manganese deposition can be summarized as follows:deposition time is 30 s,voltage is -2 V,and the concentration of Mn(II) ion is 10 mmol/L.
