Group Abstract

In recent years, first-principles based simulations can provide a faster and cost effective way to screenmaterials and to predict their relative performance. In reality, to test each and every material by the experimentalists generally needshuge resources, funding and of course, a lot of time. The first-principles based calculations can predict new materials for different applications andcan alsoprovide a robust theory behind different experimental observations. Our group is primarily focusing on first-principles based investigation of “low dimensional and Pt-free materials as catalysts for CO oxidation, Oxygen reduction reaction (ORR) and CO2 conversion”, “materials for hydrogen storage”, “electrode materials for ion-Batteries”...

Recent Work

Characteristic features of the d-band in electronic structure of transition metals have been quite effective as descriptors of their catalytic activity towards oxygen reduction reaction (ORR). With the promise of graphene-based materials to replace precious metal catalysts, descriptors of their chemical activity are much needed. Here, we propose a site-specific electronic descriptor based on the pz (π) orbital occupancy and its..
