Electrochemical properties of Ti3O5 powders prepared by carbothermal reduction

In this work, Ti3O5 powders were successfully synthesized from anatase-TiO2 by carbothermal reduction method. The products synthesized in different carbon black content and reduction temperature were investigated. The results show that Ti3O5 powders with a small amount of Ti4O7 can be obtained with carbon black content of 3.8 wt% at 1300 degrees C for 3 h in vacuum. The Ti3O5 particles were uniformly and not agglomerated, and the average particle diameter is 3.23 mu m. The cyclic voltammetry method was used to investigate the electrochemical properties of Ti3O5. The results show that Ti3O5 powders have good electrochemical activities and electrochemical stability under strong sulfuric acid and alkaline conditions.
