The work aims to improve contact between surface active layer and substrate, capacity of active substance as well as stability of electrode by introducing active substance nanotube interlayer, and enhance active specific surface area of electrode and electrocatalytical activity of Sb-SnO2 electrode by constructing apparent morphology. With TiO2 nanotube arrays as the interlayer, novel hierarchical flower-like Sb-SnO2 electrode was fabricated in the method of two-stage pulse electrodeposition. Highly ordered TiO2 nanotube array was obtained on the surface of Ti substrate in the method of anodic oxidation. During the preparation process, reverse pulse electrodeposition (8 ms, 833 mA/cm2; 2 ms, ?833 mA/cm2; 0.99 s, 0 A) was completed to construct distinct tube-in-tube structure and further compact Sb-SnO2-coated TiO2-NTs layer. Pulse signal (5 ms, 200 mA/cm2; 195 ms, 0 mA/cm2) was applied to obtain flower-like morphology. Electrochemical test showed that oxygen evolution potential of the electrode was 2.0 V (vs. SCE) and phenol oxidation peak appeared at nearly 1.7 V, charge transfer resistance was 50.4 Ω and accelerated life result could be up to 39 h. Electrochemical phenol degradation test showed that the TiO2-NTs@Sb-SnO2 could remove 97% of phenol after 4 h electrochemical degradation, and first-order kinetic rate constant of phenol degradation was 14.9×10?3 min?1. An electrode prepared in the method of pulse electrodeposition exhibits good stability and electrocatalytic removal capacity of phenol.
