Good as gold: A Au@C nanocomposite comprising 3–5 nm gold clusters confined within few-layered, highly defective graphitic cages is prepared; this nanocomposite exhibits high catalytic activity and excellent stability for the electrooxidation of methanol. The defective graphitic layers prohibit chemical/thermal coarsening of the gold clusters and also provide effective penetration channels for the transport of ions/electrons during the catalytic reaction.

将金纳米簇限制在高度缺陷的石墨层中以增强甲醇的电氧化反应

像金一样好：制备了一个Au @ C纳米复合材料，该复合材料包含限制在几层高度缺陷的石墨笼中的3–5 nm金簇；该纳米复合材料显示出高催化活性和优异的甲醇电氧化稳定性。有缺陷的石墨层阻止了金团簇的化学/热粗化，并且还为催化反应期间的离子/电子传输提供了有效的渗透通道。
