报告内容摘要

The size and structure of nanomaterials are crucial for their catalytic activities. How to understand and even control the size and structural evolution of nanocatalysts under reaction condition is a big challenge in heterogeneous catalysis. With the development of advanced in-situ techniques, the variation of size and structures of nanomaterials have been observed and real-time tracked. However, despite the experimental achievements, the understanding and precise prediction of these evolutions is still a challenging and demanding task. Herein, we developed a series of multi-scale models to quantitatively simulate the static and dynamic structural and activities’ evolution of metal nanoparticles under different experimental conditions, including size, composition, temperature, pressure, gas/liquid, gas mixtures and supports. Moreover, we also reported the recent advancements on the structural evolution of supports and  interface during reaction conditions. Our work offers possibilities for obtaining atomic-scale structures and insights beyond the experimental limits.
