Heterogeneous Catalysis is an important research area for energy, environment and sustainability. Within this domain, first-principles calculations by density functional theory (DFT) provides detailed atomistic level understanding of the nature of active sites and elucidate mechanistic insights of a particular catalytic process. The active site is the heart of any heterogeneous catalyst. This study essentially goes into characterizing the catalyst for their electronic structure which are crucial for understanding and improving of their performance in a particular process reaction. Moreover, this first-principles approach guide us to design materials at their nanoscale for potential application. Apart from this, the catalyst materials are synthesized, experimentally characterized and tested for their performance. The results of the computational and experimental studies are integrated to obtain structure-activity and structure-property correlation. The ultimate goal is to develop materials with improved properties for desired process reaction by understanding these correlations. In particular, research thrust will be given to the following topics.
1. Utilization of CO2 and CH4 for production of fuels and chemicals
2. Catalyst development for syngas conversion, COx free hydrogen generation
In addition, the following research topics will be explored.
3. Design of materials from first-principles
4. Catalytic pollution control
5. Utilization of solid waste
