报告摘要：

With the growing demand for sustainable energy and low-carbon technologies, understanding the fundamental mechanisms governing metal/oxide surface and interface reactions is essential for the rational design of advanced materials and the development of green metallurgy. In this talk, I will present our recent progress in elucidating the dynamic evolution of metal–oxide systems under reactive conditions, with a focus on atomic-scale reaction mechanisms. Particularly, I will discuss how surface atomic structures regulate gas molecule adsorption and dissociation, highlighting the synergistic roles of crystal orientation, surface defects, and phase structure in controlling metal oxidation kinetics. I will then introduce our findings on gas-dependent oxide reducibility, including the identification of atomic diffusion pathways that govern reduction behaviors. Finally, I will demonstrate how structural evolution dictates catalytic performance. The talk will conclude with a perspective on extending these insights to practical catalytic systems, aiming to enable rational catalyst design and support the transition toward low-carbon technologies in alignment with national “Dual Carbon” goals.
