Iron cation vacancies in Pt(iv)-doped hematite

Anenburg, Michael; Wykes, Jeremy; Troitzsch, Ulrike; Le Losq, Charles; Chen, Jeff

Description

Platinum-doping of hematite (α-Fe2O3) is a popular method to increase the performance of hematite in photoelectrochemical applications. The precise mode of Pt incorporation is however unclear, as it can occur as Pt0, Pt2+ or Pt4+, either on the surface, as dispersed inclusions, or as part of the hematite crystal lattice. These different Pt-doping varieties can have major effects on the hematite performance. Here, we employ a high-pressure synthesis method assisted by silicate liquid flux to...[Show more]
