Fig. 4From: Facile Preparation and Characterization of Polyaniline and CeO2 Co-Decorated TiO2 Nanotube Array and its Highly Efficient Photoelectrocatalytic ActivityThe effect of different pH on TBBPA degradation efficiency in photoelectrocatalytic process under simulated daylight irradiation. The geometric surface area of TiO2 electrode was 2.0 × 2.5 cm2. Initial concentration of TBBPA: 10 mg L− 1, volume: 50 mL, electrolyte: 0.05 M Na2SO4, bias potential: 9 VBack to article page
