photoelectrode was synthesized on a FTO substrate from chemical bath deposition and electrochemical deposition to investigate the photoelectrocatalytic (PEC) degradation of tetrabromobisphenol A (TBBPA). XRD, SEM, UV–vis and PL techniques were employed to evaluated the crystal structure, surface morphology, light absorbance properties and efficiency of carriers’ separation of the obtained electrode, respectively. The ZnO/Bi2
photoelectrode yielded a photocurrent density of 15.3 mA/cm2
upon ultraviolet and visible light irradiation, which was 6.6 and 10.9 times that of the original ZnO and Bi2
, respectively. The enhanced photoelectrochemical properties is due to theimproved light absorption of Bi2
nanoparticles and accelerated electron‐transferpathway of ZnO nanorods. The stability of the photoelectrode was evaluated byrecycling degradation experiments for 3 times. The intermediates of TBBPAdegradation were also identified and a possible pathway was proposed.
