Electrochemical properties of the TiO2 B
The synthesized TiO2 B powders were ball milled using a planetary type ball mill at a fixed rotation speed of 300 rpm for up to 3 hrs to make them smaller sizes The changes of morphology and size of the powders with the milling time were observed under SEM as shown in Figure 1 The as synthesized TiO2 B powders were observed from Figure 1 a
