纳米片的二维结构和可调特性使其成为令人感兴趣的催化材料。这一研究领域的发展是为了替代能源技术中稀缺的贵金属催化剂。我们描述了纳米片电催化氧还原、析氧、析氢和二氧化碳还原反应的最新进展。我们发现，在发展的早期阶段，纳米片催化在其中一些应用中已经超越了传统的贵金属催化剂，并且在其他应用中显示出巨大的潜力。目前，无金属碳纳米片可以最好地催化二氧化碳还原为甲烷。这些趋势可能会改变多相催化。
The 2D structures and tunable properties of nanosheets make them intriguing catalytic materials. This research area is being driven by a need to replace scarce noble metal-based catalysts in energy technologies. We describe recent advances in nanosheet electrocatalysis of oxygen reduction, oxygen evolution, hydrogen evolution, and CO2 reduction reactions. We find at this early stage of development that nanosheet catalysis has surpassed classical noble metal catalysts in several of these applications and is showing high potential in others. CO2 reduction to methane is now catalyzed best by metal-free carbon nanosheets. These trends will likely transform heterogeneous catalysis.
