Abstract

First principles-based computational modelings propose key dscriptors and design concepts for discovering highly active materials in renewable energy system application. Density functional thoery calculations combined with statistical mechanical formalism identify optimum catalysts for oxygen (hydrogen) reduction (oxifation) and evolution reactions beyond concentional Pt used in fuel cell and Li-ion batteries. In this talk, the author will present the reaction mechanism of environmentally toxic gases with water and suggest how to remove them by designing efficient filters. Organic iodine and POCl3 are introduced as the examples.
