基于石墨烯量子点的多相催化剂

摘要

石墨烯量子点作为纳米炭家族中独特的一员,由于其高比表面、丰富的表面化学反应位点和高电荷转移性能,已成为全解水和金属-空气电池等领域中的重要催化剂。了解石墨烯量子点在多相催化中的催化机理有助于合理设计高性能石墨烯量子点基催化剂。本文综述了近年来石墨烯量子点基多相催化剂的合成、改性及在全解水、金属-空气电池等领域应用的研究进展。讨论了目前石墨烯量子点基催化剂研究中存在的问题,并对设计高性能石墨烯量子点基催化剂的前景进行了展望。Graphene quantum dots(GQDs),as a unique member of the nanocarbon family,have become important catalysts for overall water splitting and metal-air batteries because of their high specific surface area,abundant surface chemical reaction sites and high electron mobility.Understanding the fundamental catalytic mechanism of GQDs in heterogeneous catalysis is conducive to the rational design of high performance GQD-based catalysts.This article summarizes current research progress in the synthesis,modification and applications of GQD-based heterogeneous catalysts in overall water splitting,metal-air batteries and other fields.The issues related to the use of GQD-based catalysts in these fields are discussed together with their future development.
