综述了石墨烯支撑三明治结构材料的可控合成及其在能量存储与转换中应用的研究进展。基于不同的微观结构,石墨烯支撑三明治结构的材料主要分为如下三类:石墨烯支撑的纳米粒子(0D),石墨烯支撑的纳米棒、纳米线及纳米带(1D),石墨烯支撑的纳米片(2D)。在这些复合材料中,石墨烯与相应功能材料间本征不相容的问题不仅得到有效解决,而且石墨烯可以作为电子传输的快速通道,有利于其能量存储与转换过程。本文为石墨烯或者类石墨烯材料支撑三明治结构复合材料的设计与合成提供了思路,这种具有特定结构的材料潜在广泛应用于催化、传感器、能量存储与转换等领域。
The controllable synthesis of graphene - supported sandwich materials and its application in energy storage and conversion are reviewed. Based on different microstructures, graphene-supported sandwich structures are mainly classified into the following three categories: graphene-supported nanoparticles (0D), graphene-supported nanorods, nanowires and nanoribbons (1D), graphene- Nanosheet (2D). In these composites, the problem of intrinsic incompatibility between graphene and corresponding functional materials not only can be effectively solved, but also graphene can serve as a fast channel for electron transport, which facilitates the energy storage and conversion process. This article provides ideas for the design and synthesis of graphene or graphene-like materials that support sandwich composites. Such materials with specific structures are potentially widely used in the fields of catalysis, sensors, energy storage and conversion.
