                         pollutants require the study of new anode materials. Porous 
                         structure of three-dimensional oxidized carbon fibers (OCF) 
                         associated to titanium dioxide (TiO2) becomes an alternative since 
                         they can effectively improve the mass transport in their enlarged 
                         areas. TiO2/OCF electrodes were produced from an optimized OCF 
                         substrate evaluating the influence of oxygen functional groups on 
                         its surface in the TiCl3 anodic hydrolysis. From scanning electron 
                         microscopy, Raman analyzes, and electro/photoelectrochemical 
                         responses, a suitable TiO2/OCF composite was obtained from 
                         oxidized CF for 30 min. TiO2 presented several characteristic 
                         Raman bands of anatase modes at 150, 398, 511, and 620 
                         cm\−1 . To improve the TiO2 crystallinity, the samples were 
                         also heat-treated at 500 °C in an argon atmosphere for 2, 3, and 4 
                         h. TiO2/OCF composite treated for 2 h presented the highest 
                         electrochemically active surface area and photoelectrochemical 
                         activity. This is due to its TiO2 rougher morphology with rounded 
                         nanoparticles presence on OCF surface. For Brilliant Green dye 
                         degradation, an electrolysis process was highly efficient at the 
                         current density of 10 mA cm\−2 at 300 min of time 
                         treatment. Besides, TiO2/OCF composite under UV irradiation shows 
                         an electrolysis efficiency improvement presenting the highest 
                         kinetic rate associated to the additional % OH radical
