Fig. 5From: Facile Preparation and Characterization of Polyaniline and CeO2 Co-Decorated TiO2 Nanotube Array and its Highly Efficient Photoelectrocatalytic ActivityThe effect of different hole scavengers (a) and ethanol amount (b) on the kinetics of TBBPA degradation. 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 V, pH: 3Back to article page
