Photochemistry: A Stable and Efficient Hematite Photoanode in a Neutral Electrolyte for Solar Water Splitting: Towards Stability Engineering (Adv. Energy Mater. 13/2014)

Surface phosphate groups facilitate solar water oxidation on the surface of iron oxide thin films, even in a neutral electrolyte. The method reported by Jae Sung Lee and co-workers in article number 1400476 provides an effective path to the stability engineering of photoelectrodes to employ any electrolyte of choice. Such stability engineering is a critical issue in solution-based energy devices based on hybrid materials with different stability characteristics.
