Abstract
Designing advanced structures for heterojunction photocatalysts is an effective approach to enhance their performance toward solar-energy conversion. Herein we develop a facile synthetic strategy for the fabrication of Fe<sub>2</sub>O<sub>3</sub>-TiO<sub>2</sub> microdumbbells. With the assistance of preferentially adsorbed hexadecylamine molecules, amorphous TiO<sub>2</sub> nanospheres with tunable size are grown at the two ends of Fe-based metal–organic compound microrods. Subsequent annealing of the hybrid obtained leads to the formation of a novel heterostructured Fe<sub>2</sub>O<sub>3</sub>-TiO<sub>2</sub> microdumbbell photocatalyst. Owing to the heterojunction formed and the unique structure, Fe<sub>2</sub>O<sub>3</sub>-TiO<sub>2</sub> microdumbbells with optimized composition and morphology show enhanced performance for photoelectrochemical water oxidation, compared to monophasic Fe<sub>2</sub>O<sub>3</sub> and TiO<sub>2</sub> materials as well as physical mixtures thereof. © 2018 Wiley-VCH Verlag GmbH & Co.
