Today’s society is faced with two persistent demands: sustainable energy production and a healthy living environment. In this line of research our team seeks to address both issues using a single device; an all-gas-phase and stand-alone photoelectrochemical (PEC) cell. In doing so part of the energy stored in airborne organic pollutants is recovered by hydrogen production, while mineralizing the contaminants to less harmful CO2. Oxidation of volatile organic compounds (VOC) occurs at the photo-anode, while hydrogen is produced at the (dark) cathode on the opposite side of a proton-conducting solid electrolyte membrane.
