  报告摘要:

  Owing to the development in modern theoretical and computational chemistry (e.g., density functional theory), predicting molecular properties using accurate and efficient quantum chemistry methods becomes more and more practical. As a consequence, inverse molecular design approaches based on quantum chemistry have emerged as an attractive computational approach to take on the challenges in materials discovery.

  First, through the collaboration with the Green Chemistry and Green Engineering Center at Yale University, we explored the theoretical limits of reaction conditions for the hydrogenation and hydrogenolysis of biomass model compounds, using quantum chemistry calculations based on density function theory. Our results showed that thermodynamically it is indeed possible to design green hydrogenation catalysts that can work at the mildest conditions for converting biomass molecules into value-added chemicals.1 The thermodynamic study also helped us to understand the selectivity of an existing Cu-doped hydrotalciate catalyst in experiments.2 Second, we developed a new inverse molecular design method based on tight-binding electronic structure theory to search for novel hydrogenation catalysts. In this presentation, I will introduce the history of inverse molecular design method developed in my laboratory, based on the tight-binding electronic structure theory and the scheme of linear-combination-of-atomic-potential (called TB-LCAP). Our approach of inverse molecular design aims at searching for optimum points on the hypersurfaces defining the property-structure relationships, and then mapping out the molecular structures at the optimum points, leading to enhanced efficiency and success rate for materials discovery. We have applied the TB-LCAP inverse design method to successfully design nonlinear optical materials and dye-sensitized solar cells. Our results indicate that the inverse molecular design approach could be a useful tool to search for promising green heterogeneous catalysts for converting lignocellulosic biomass into value-added chemicals such as liquid fuels.
