A stable and efficient hematite photoanode that works for solar water splitting, even in a neutral electrolyte, is developed by surface modification with phosphate ions. By preventing performance and stability degradation in a neutral electrolyte, the current method provides an effective path to the stability engineering of photoelectrodes to employ any electrolyte of choice.
