Li Group
Welcome to the homepage of Dr. Li's research group!
About
The research interests of the Li group aim at the rational design of nanostructured gels-derived single-atom materials to address scientific challenges in energy and environment sustainability. We especially focus on the scaling relationship between the structures and intrinsic behaviors with the aid of in situ characterizations and computational modeling. We also concentrate on designing the flexible and wearable energy storage devices.
Research
Nanostructured gels-derived single-atom materials
Nanostructured gels synthesized from monomers or building blocks are featured with three-dimensional and cross-linked networks, which are emerged as an appealing materials platform for energy storage and conversion. Due to the inherited advantages of gels precursors, gels-derived materials show a great potential in addressing synthetic challenges in single-atom materials by precisely controlling the site density and coordination state, providing hierarchical architectures with high atomic utilization, and high processibility for the large-scale production. Our group mainly focus on the synthetic strategy of gels-derived single-atom materials with controllable physiochemical properties.
Scaling relationship and mechanistic study in electrocatalysis
Single-atom catalysts (SACs) are defined as catalysts in which all active metal species are atomically dispersed and stabilized by the support, which are featured with low-coordination environment, the discrete energy level, and the metal-support interaction. Therefore, the electrocatalytic property of SACs can be finely tuned by modulating the electronic structure, which is greatly affected by the local environment, such as the support, neighboring atoms, and inter-sate distance. Our group aims at studying the scaling relationship between the structures of gels-derived SACs and intrinsic electrocatalytic activity. Combining the theoretical modelling into experiments, the catalytic mechanism is investigated as well.
Sustainable energy and resources conversion
The electrocatalytic synthesis driven by the renewable electricity is a sustainable route to convert energy and resources to value-added chemicals. Since the reaction process can be controlled by varying the potential and current. the desired species can be produced in a high selective, efficient, safe, and on-demand way. In our group, the highly active SACs are developed to facilitate the efficient cleavage and formation of chemical bonds, further conversing the valuable chemicals (e.g. NH3) from pollutions, which can decentralize the fossil-fuel-based products and alleviate the environmental issues.
