The feasibility of a solar-driven photoelectrochemical process to generate hydrogen fuel from metal mine polluted water while simultaneously recovering heavy metals has been explored. Electron transport from the photoanode to the cathode plays a key role in generating hydrogen (37.6 μmol h−1cm−2at 0.2 V RHE, 1 sun illumination), and scavenging Zn2+ions in the form of ZnO.
