Computational Advancement towards Efficient Catalytic Materials – Connecting a Few Dots 

In this talk, I would like to present a two-fold research activity interconnected with a common string “Catalysis”. The first part would be dedicated to the fundamental mechanism for the solar irradiated water splitting in photocatalytic materials with the future prospect of Non-linear Poisson Boltzmann Solver development for the heterogenous catalytic mechanism.The relevant exploration of novel 2D materials and their applications in such catalytic mechanism would be elaborated subsequently [1, 2]. The mechanism corresponding to Hydrogen Evolution Reaction (HER) and Oxygen Evolution Reaction (OER) under the influence of doping and vacancy defect from DFT based theoretical perspective would be discussed [3, 4] along with our recent high throughput computational investigation of finding efficient HER catalytic materials based on transition metal tri-chalcogenides [5]. The next part of the talk would be devoted to the fundamental understanding of our recently developed interface between Hybrid Eigen-vector Following (EF) formalism and DFT to predict the Transition Pathway without the prior knowledge of adjacent minima [6]. I will conclude my talk with the external stimuli driven Rashba induced catalytic activity enhancement , where we have successfully demonstrated the effect of strain on the overpotential of the novel catalytic materials through the tuning of Rashba splitting.
