石墨烯（Graphene，GR）及其衍生物是纳米技术和材料科学领域的一种新型材料，近年来引起了人们的极大兴趣。具有sp（2）杂化和大比表面积、高热导率、上级电子迁移率和化学稳定性的独特原子厚的2D结构使得GR及其衍生物对于用于太阳能转换、能量储存、环境净化和生物传感器应用的复合材料是非常有吸引力的组分。本文简要介绍了GR的独特结构、能带结构工程、物理化学性质以及GR基材料在能量转换领域（例如，光催化剂、光电化学水分解、CO2还原、染料敏化和有机太阳能电池以及光伏器件中的光敏剂）和能量存储（电池、燃料电池和超级电容器）。介绍了GR基材料在光催化降解有机污染物、气敏和去除重金属离子等环境应用方面的广泛进展。此外，石墨烯复合材料在生物传感领域的使用进行了讨论。最后，我们评论的挑战，前景和进一步发展的GR基材料在能源，环境和生物科学的令人兴奋的领域。
Graphene (GR) and its derivatives are promising materials on the horizon of nanotechnology and material science and have attracted a tremendous amount of research interest in recent years. The unique atom-thick 2D structure with sp(2) hybridization and large specific surface area, high thermal conductivity, superior electron mobility, and chemical stability have made GR and its derivatives extremely attractive components for composite materials for solar energy conversion, energy storage, environmental purification, and biosensor applications. This review gives a brief introduction of GR's unique structure, band structure engineering, physical and chemical properties, and recent energy-related progress of GR-based materials in the fields of energy conversion (e.g., photocatalysis, photoelectrochemical water splitting, CO2 reduction, dye-sensitized and organic solar cells, and photosensitizers in photovoltaic devices) and energy storage (batteries, fuel cells, and supercapacitors). The vast coverage of advancements in environmental applications of GR-based materials for photocatalytic degradation of organic pollutants, gas sensing, and removal of heavy-metal ions is presented. Additionally, the use of graphene composites in the biosensing field is discussed. We conclude the review with remarks on the challenges, prospects, and further development of GR-based materials in the exciting fields of energy, environment, and bioscience.
