As emerging materials, multifunctional hybrid nanomaterials usually integrate two or more disparate materials and represent a powerful approach for achieving advanced nanomaterials with unique properties. With carrying such unique advantages, multifunctional hybrid nanomaterials have vast potential applications in chemical and biological sensing, in heterogeneous catalysis, in energy conversion and storage, and in environment and human health. Important requirements to the hybrid nanomaterials include a high specific surface area, a particular well-controlled size, a homogeneous distribution, and a strong attachment between the nanomaterial interfacial surfaces. In addition, the ability to tailor the structures and properties of hybrid nanomaterials over broad length scales suggests that researches on hybrid nanomaterials will have a tremendous impact in the fields of polymer, carbon, nanotechnology, physical chemistry, and electrochemistry. However, the preparation of the multifunctional nanomaterials and their integration into practical applications are not yet satisfactory. Therefore, it is highly desirable to provide a breakthrough on the state-of-the-art nanomanufacturing and scale-up nanotechnology to prepare advanced multifunctional hybrid nanomaterials.

In this special issue, we cordially invite researchers to contribute high quality, original research papers and review articles with shared interests regarding the multifunctional hybrid nanomaterials.
