林海平博士毕业于英国利物浦大学(The University of Liverpool),Werner Hofer教授的课题组。在STM模拟计算软件的代码编写,以及STM模拟新方法的发展方面具有丰富、扎实的工作经验。曾经多次作为技术骨干参与完成了欧洲EPSRC科技项目,成功地为丹麦科技大学的GPAW计算软件开发了基于非平衡格林函数STM模拟计算方法,该方法克服了传统的Bardeen方法中仅对STM针尖和样品表面之间的真空层进行电子输运计算的不足之处,能够完整地对STM成像过程中电子输运的各个环节进行准确地计算,有效地扩大了STM模拟技术在表面科学领域的应用范围。曾与国际知名STM实验小组进行紧密地合作,共同发表2篇Nature Chemistry, 2篇J. Am. Chem. Soc. 和 2篇Phys. Rev. Lett.。回国以后开辟了表面催化化学的理论研究方向,致力于研究发生在金属表面和负载表面的C-H键 活化和C-C偶合反应的理论模拟与计算,在Nature Communications (1篇), J. Am. Chem. Soc. (4篇), Angew. Chem. Int. Ed(1篇), ACS Nano(2篇), Nano Letters(1篇)和 J. Mater. Chem. A(2篇) 等国际权威期刊上发表论文近30篇。 |

The first part of this talk is to discuss our effort in the development of first-principles STM simulation methods and their applications in the field structural determinations and analysis of on-surface reaction mechanisms. In the second part, I would like to present our recently researches in the field of rational design of heterogeneous catalysts, which may increase the HER efficient by 7.8% in comparison with Pt/C, and increase the conversion efficiency of propane to propene by 40.0% in comparison with Pt-Sn. |
