Abstract: This report is of the Ninth Cross Strait Symposium on Advanced Carbon Materials, which was held at National Tsing-hua University in Hsin-Chu, Taiwan, Oct. 4-6, 2010. More than 60 scientists, including 33 experts from Mainland China, attended the symposium. Forty-two papers including four plenary lectures were presented. The symposium involved six topics including catalytic properties of carbon nanomaterials, microstructure, processing, composites, graphene as well as bio-related carbon materials and new applications. The four plenary lectures focused on the synthesis and characterization of graphene, catalytic behavior of carbon nanomaterials, and novel design of the diffusion layer in a fuel cell.
