Promoting the applications of metal oxide materials for broader and larger scales relies on a proper understanding of their structure-property relationships. This, in turn, requires greater knowledge and abilities to control the size, shape, morphology, and chemical composition in wet-chemistry syntheses of metal oxyhydroxide/ oxide materials [1] . One interesting aspect is the controlled synthesis of materials with heterostructures, which have potential applications in the areas such as catalysis [2] , electronics [3] , spintronics [4] , and optics [5] etc. Heterostructures can be prepared via various methods and approaches. In this poster, we present a simple approach to synthesise α-FeOOH/α-Fe 2 O 3 heterostructures via regulating hydrothermal conditions and the reaction precursors. The results show a series of samples with varied morphologies and chemical/phase compositions, which are characterized by XRD, SEM, EDX, FT-IR, and UV-Vis. References
