高效催化氧还原及氧析出反应的掺杂石墨炔的设计与理论计算
Design and Theoretical Calculation of Heteroatoms Doped Graphdiyne Towards Efficiently Catalyzing Oxygen Reduction and Evolution Reactions
摘要
Abstract
In the process of clean and renewable energy conversion,oxygen reduction reaction and oxygen evolution reaction demand highly efficient electrocatalysts to overcome their kinetic bottlenecks . Herein,a series of metal-free graphdiyne doped with heteroatoms was designed for promoting these key chemical reac?tions. To evaluate electrocatalytic performance,the reaction pathways and free energies were investigated sys?tematically with the density functional theory(DFT). The calculations indicated that the dopants can optimize the adsorption of intermediates,lowering the overpotential of the reactions. Particularly,an intrinsic descriptor was identified to correlate the catalytic properties with catalyst structures ,from which rapid screening could be made for the development of new catalysts. The results may provide guidance for the construction of carbon-based catalysts in clean energy technologies(such as fuel cells,metal-air batteries,electrolyzing water and so on).关键词
