摘要:
A visible-light driven photoelectrochemical (PEC) cell comprised of nanostructured BiVO4 photoanode and Pt cathode was established for organic compounds degradation with simultaneous H2 generation.BiVO4 electrode film fabricated by a simple drip-coating method showed a porous nanostructure and an intense absorption in visible light range.The PEC process possesses a rate of about 0.3207 h-1 for MO degradation,which is 8 times and 64 times faster than electrocatalytic (EC) and photocatalytic (PC) process,respectively.A simultaneous H2 generation via the PEC process was also observed and a rate of 34.44 μmolh-1cm 2 for H2 generation was measured,which is 3 folds more efficient than the EC process.The nanostructured BiVO4 photoanode shows outstanding PEC photocurrent density and recycle performance.The proposed PEC system would be a promising strategy for wastewater treatment and energy recovery with an outstanding stability and recyclability performance.
