主讲内容：Heteronanostructures (HNs) that integrate two or more nanocomponents represent an important family of advanced nanomaterials due to the synergistic effects induced by direct electronic and magnetic communications between the constituent nanocomponents, which have been applied to different areas including optoelectronics, catalysis, solar energy conversion, sensing, environmental remediation, and biomedicine. To fully exploit the synergistic coupling effects of the HNs, the development of a general methodology that enables precisely control over each nanocomponent and their interfaces is still imperative. Herein, an innovative concept was proposed to achieve large-scale arrays of HNs with high degrees of controllability for each of the sub-components, including material, dimension, morphology, and their interfaces. This HNs concept originates with a distinctive binary-pore AAO template that includes two dissimilar sets of pores in one matrix, where the openings of the two sets of pores are towards opposite sides of the template. Using the same growth mechanism, the binary-pore AAO template can be extended to multipore AAO templates with more geometrical options. Finally, we use these HNs in proof-of-principle photoelectrodes, transistors and plasmonic devices. The enabled HNs demonstrated here could allow us to study the structure-property relationship from the fundamentally microscopic muticomponets to assembled macroscopic array of multicomponent on a large scale.
