Here, we present the catalytic conversion of graphene layers into carbon nanotubes (CNTs), in the presence of Au nanoparticles (AuNPs) without the need for an additional carbon source. We have demonstrated that this catalytic process takes place at temperatures as low as 500 °C. No other oxide supports decorated with AuNPs were found to grow CNTs at this temperature. These findings highlight the high activity of graphene when used as a support for catalytic reactions.
在这里，我们展示了在没有额外碳源的情况下，金纳米粒子（AuNPs）存在下，将石墨烯层催化转化为碳纳米管（CNTs）的过程。我们已经证明，这个催化过程可以在低至 500°C 的温度下进行。在这个温度下，没有发现其他氧化物载体负载 AuNPs 可以生长 CNTs。这些发现强调了石墨烯作为催化反应的支持物时的高活性。
