能源问题是21世纪世纪最具挑战性的问题之一。便携式电子产品、电动汽车、航天器和可再生能源的许多能源应用正在全球范围内进行广泛的研究。具有可再生能源装置的新的替代能源与化石燃料竞争。为了开发先进的能量储存和收集/转换系统，可再生能源纳米材料的需求很高。由石墨烯和二维过渡金属硫族化合物（2D-TMDs）组成的二维纳米材料由于其独特的性质引起了人们的极大兴趣。从能源应用的前景来看，石墨烯和二维TMD纳米片具有许多有趣的特性，如大的表面积、原子级薄且具有高柔韧性的片以及宽范围的导电性。石墨烯已被证明是用于能量收集/转换和存储应用的纳米器件的良好材料。最近，2D-TMD在许多与能源相关的应用中也引起了极大的关注。在本章中，我们重点介绍了石墨烯（包括氧化石墨烯，GO）和2D-TMD纳米片在能源器件方面的最新研究进展：太阳能电池电极，燃料电池电催化剂或光催化剂，锂离子电池电极，超级电容器电极。
The energy problem is one of the most challenging issues in the twenty-first century. Many energy applications for portable electronics, electric vehicles, spacecraft, and renewable energy are under extensive investigation worldwide. New alternative energy with renewable energy devices are competitive with fossil fuels. To develop the advanced energy storage and harvesting/conversion system, renewable energy nanomaterials are in high demand. Two-dimensional nanomaterials composed of graphene and two-dimensional transition-metal chalcogenides (2D-TMDs) have attracted a great deal of interest due to their unique properties. From the prospect of energy applications, graphene and 2D-TMD nanosheets have many interesting properties, such as large surface area, atomically thin sheet with high flexibility, and a wide range of electrical conductivity. Graphene has proved to be a good material for nanoscale devices used in energy harvesting/conversion and storage applications. Recently, 2D-TMDs are also attracting significant attention in many energy-related applications. In this chapter, we focus on the recent advances in graphene (including graphene oxide, GO) and 2D-TMD nanosheets research for energy devices: electrodes in solar cell, electrocatalysts or photocatalysts for fuel cell, electrodes in Li-ion battery, and electrodes for supercapacitors.
