Synthesis of Fe2TiO5/Fe2O3/Pt Photoanodes and Photoelectrocatalytic Water Decomposition Solar energy (electro) catalytic decomposition of water to hydrogen is one of the ideal ways to solve the current energy shortage and environmental pollution problems. Iron Oxide (α- Fe 2 O 3) has advantages of high stability, low energy band structure (2.1eV) and abundant natural reserves. It has become an important material in the field of photocatalytic water decomposing hydrogen production. However, iron oxides have the disadvantages of poor conductivity, faster electron-hole recombination, and other limitations, which severely limit their practical application. Institute of Lanzhou Institute of Chemical Physics, Lanzhou Institute of Chemical Physics, China, and Patrik Schmuki, Professor, University of Erlangen-Nuremberg, Germany, collaborate to study the photoelectrocatalytic water splitting of ultra-thin α- Fe 2 O 3 materials and the separation of their photogenerated charges. Make new progress. The researchers grew thick Pt nanometal layers on conductive substrates and deposited ultrathin α- Fe 2 O 3 nanolayers. On the basis of α- Fe 2 O 3 /Pt, Fe 2 TiO 5 layer was further synthesized in situ to form a Fe 2 TiO 5 /α- Fe 2 O 3/Pt “sandwich†heterostructure photoanode. In this structure, the metal Pt nano-layer can effectively improve the light absorption performance of α- Fe 2 O 3 . Because of its low Fermi energy level, it can effectively promote the separation of photo-generated carriers and the rapid migration of photo-generated electrons. Further, Fe 2 TiO 5 and α- Fe 2 O 3 composite has a matching probability of band structure, the photogenerated holes nano-α- Fe 2 O 3 layer is quickly migrate to Fe 2 TiO 5 layer, a further reduction of the carrier And promote water oxidation. Under simulated sunlight (AM 1.5G, 100 mW cm-2), the “sandwich†heterostructure Fe2TiO5/α- Fe 2 O 3/Pt photoanode exhibited excellent photoelectrocatalytic water activity and stability. The photocurrent density increases nearly 1.5 times compared to the pure phase αFe 2 O 3 . The design of the heterostructure photoanode can effectively improve the light absorption performance of semiconductor materials, and promote the rapid separation and migration of photogenerated charge, which has guiding significance for the construction of high-efficiency solar photoelectrocatalytic water decomposition system. The results of related studies are published in Advanced Functional Materials and Journal of Materials Chemistry A.
