Decontamination of polluted water sources is a demanding challenge, as is on-site decontamination at the pollution source before release in the environment. Oxyanions are a key family of contaminants which are central to agriculture and industrial processes. Efficacious remediation methods require a better understanding of the fundamental reactions involved. Recent results from our group will be discussed on electrochemical methods for the energy-efficient detection and reduction of highly carcinogenic hexavalent chromium from contaminated waters. The proton-coupled electron transfer (PCET) processes underpinning the reaction will be uncovered and the impact on the energy efficiency of the reaction discussed. We demonstrate that cheap electrodes can be used and highlight the role of acid choice in facilitating the PCET processes.
