报告摘要:Gold was regarded as an inactive element for longer than a century. However, it exhibits unique catalytic properties when deposited as nanoparticles (NPs) below 5 nm in diameter on a variety of materials such as oxides, carbides, and sulfides of transition metals, carbons, and organic polymers. The catalytic performance of gold NPs and clusters with diameters smaller than 2 nm has been explored extensively for reactions of both gases and liquids. Supported gold catalysts are useful for air cleaning at room temperature and for green production of bulk and fine chemicals. Supported gold clusters are expected to open a door for simple chemistry, which enables us to selectively produce what we need. We are currently investigating the size and structure specificity of gold and exploring suitable support materials for air purification elimination.
