摘要：
Nowadays, stable photoelectrochemical seawater desalination is a challenge. In this work, an environmentally friendly WO3/BiVO4 photoanode is reported to achieve stable solar-driven redox desalination. The WO3/BiVO4 photoanode was prepared by the hydrothermal method and drop-casting and the cathode is the activated carbon coated on graphite paper. Within the desalination system, the I-/I3 � redox species are recycled between anode/ cathode chambers. In the short-circuit state, with illumination as the driving force, the salt removal rate of 65.03 & mu;g/(cm2 & BULL;min) is obtained without the electric consumption. During the desalination process, the energy output process can be implemented with a salt removal rate of 29.8 & mu;g/(cm2 & BULL;min) with constant current discharge. Importantly, the solar desalination system based on WO3/BiVO4 photoanode is quite stable. Within the five
