|
Abstract:
还原氧化石墨烯(RGO)因其独特的二维结构和优异的电子性质，在催化领域展现出巨大潜力。本文以氧化石墨烯(GO)为原料通过水热还原的方法制备了RGO，并结合机理讨论与机理验证的方法，对比探究了RGO和GO的过氧化物催化性能。通过实验结果发现，RGO的过氧化物催化性能优于GO，其原因在于RGO具有更高的电子迁移率。这一发现揭示了电子迁移率与过氧化物催化性能之间的密切关系。本研究为设计高效石墨烯基过氧化物催化剂提供了理论依据和新思路，对推动其在环境治理、能源转换等领域的应用具有重要意义。
Reduced graphene oxide (RGO) shows great potential in catalysis due to its unique two-dimensional structure and excellent electronic properties. In this paper, graphene oxide (GO) was used as raw material to prepare RGO by hydrothermal reduction method. Combined with mechanism discussion and mechanism verification methods, the peroxide catalytic properties of RGO and GO were compared and explored. The experimental results show that the peroxide catalytic performance of RGO is better than that of GO, which is due to the higher electron mobility of RGO. This discovery reveals a close relationship between electron mobility and the catalytic performance of peroxides. This study provides theoretical basis and new ideas for the design of efficient graphene-based peroxide catalysts, and has important significance for promoting its application in environmental governance, energy conversion and other fields.
