Our research aims to synthesize, characterize and develop novel but “simple” catalysts, based on metal/metal oxide nanoparticles, for applications in organic reaction, fuel cell and bio-medicine.
We utilized a so-call “polymer template” method for the synthesis of monodisperse nanoparticles with size range from 1~10nm. Due to the extremely small size of such nanostructure, a very large fraction of the atoms making up nanoparticles are located on the particle surface, which lead to a series of unique properties that are not observed on the macro-size materials. We also explore other synthetic approaches, such as sol-gel method, coprecipitation, to fabricate multi-component and multi-functional nanoparticulate materials with or without support.
The major applications of the synthetic nanoparticles that we interest are in the following aspects.
(1) Heterogeneous catalysis for organic reaction, biomass decomposition, and pollutant mediated formation. It is well known that the extremely small dimension of metal/metal oxide nanoparticles not only show superior reactivity in organic reaction than those traditional micro-size catalysts, they may also lead to selected products due to their pertinent surface structure.
(2) Solid oxide fuel cell. It has been reported that the using of nanoparticles in solid oxide fuel cell can significantly increase the release speed of hydrogen.
(3) Biomedical research including nanotoxicity evaluation, imaging agent, and disease therapy.
We also interest with the synthesis of novel biocompatible chromophores, which can be incorporated with our nanoparticles projects and macromolecule template for a broader environmental/biological application, such as metal sensor for water qualification, drug delivery marker, and so on.
