结晶石墨纳米片（GPs）含有几层大致垂直于衬底生长的石墨烯，由于其独特的优点，如大的表面积、超尖锐和暴露的边缘、快速的电子转移动力学以及出色的机械、化学和电化学性能，在能量存储和传感应用中引起了广泛的关注。可以使用各种前体（例如，固体、液体或气体）。本文综述了GP的生长机制及其独特的性质，并总结了基于GP的功能器件在电化学储能和生物传感等方面的最新发展。最后，本文还讨论了未来工作的挑战和前景，以充分发挥独特的石墨烯材料的潜力。这篇综述将鼓励GP在不同领域的应用，并启发新的研究探索其他独特的二维纳米结构。
Crystalline graphitic nanopetals (GPs), containing a few layers of graphene that grow roughly perpendicularly to a substrate, have attracted much attention in energy storage and sensing applications because of the unique advantages such as large surface area, ultrasharp and exposed edges, fast electron transfer kinetics, and outstanding mechanical, chemical, and electrochemical properties. GPs can be deposited on various substrates using a wide range of precursors (e.g., solids, liquids, or gases) by a catalyst-free plasma-enhanced chemical vapor deposition (PECVD) process. This review provides insights into the growth mechanisms of GPs and their unique properties, and summarizes the latest development of GP-based functional devices for many applications such as electrochemical energy storage and biosensing. Finally, challenges and perspectives for future work are also discussed in this article to fully exploit the potential of the unique graphene material. This review will encourage the applications of GPs in diverse fields and inspire new studies on the exploration of other unique two-dimensional nanostructures.
