  报告摘要: 

  Past decades have witnessed tremendous advances in the development of novel nanomaterials for electrocatalysis. In this talk, I review our recent efforts to computationally design nanomaterials for electrocatalysis based on first-principles modeling. Several nanostructures, including nanoparticles/nanoplates, nanowires and near-surface alloys are examined for oxygen reduction reaction (ORR) and CO2 electroreduction (CO2RR). We have developed a multiscale computational framework to design core/shell nanoparticles for electrocatalysis. We proposed that generalized coordination number could be used as a descriptor to characterize CO2RR on metal surfaces based on which one can construct activity-volcano plots and derive theoretical overpotential limits on the surfaces. We also predicted a number of near-surface alloys and single-atom alloys which show promise of highly active and selective catalysts for formic acid, carbon monoxide, methanol, and ethylene production, while simultaneously suppress competing hydrogen evolution reaction. 

    

  报告人简介: 

  Prof. Lu received his Ph. D from Chinese Academy of Sciences while most of his Ph. D work was carried out in his current institution - California State University Northridge (CSUN). After a postdoc appointment at Harvard, Prof. Lu returned to CSUN as a faculty member in 2004 and was promoted to a full professor in 2009. He is the director of NSF-funded PREM center and the founding director of the Center of Excellence in Materials Innovation, both at CSUN. Prof. Lu spends significant research effort in developing first-principles based multiscale computational methods and has applied these methods to various important materials problems. Some of the problems relevant to electrocatalysis will be highlighted in the talk.
