Characterizing surface states in hematite nanorod photoanodes, both beneficial and detrimental to solar water splitting efficiency

Direct evidence for reductive and oxidative surface states coexisting in hematite nanostructures is given by combined STXM and PEC measurements. The annealing temperature and Ti substitution balance the surface states, driving the PEC activity.
