Trace Amounts of Co3O4 Nano-Particles Modified TiO2 …
of Co3O4 modified TiO2 nanorod arrays and pure TiO2 nanorod arrays. The Co3O4 modi-fied TiO2 and pure TiO2 nanorod arrays with a geometric area of 1.0 cm 1.0 cm were used as the working electrode, as well as platinum as the counter electrode and saturated calomel electrode (SCE) as the reference electrode. A 500 W Xe lamp was …
