On March 21, 2026, our research on the PtSnCu single-atom alloy  catalyst for propane dehydrogenation (Science 2025, 0, eadw3053) has been selected by Science & Technology Review as one of the "2025 Major Scientific, Technological and Engineering Advances in China." The work was recognized under the category of 2025 Major Scientific Advances in China.

According to the official evaluation, the study identified a new mechanism of metal atom segregation driven by differences in atomic size and bonding strength between metal atoms, and, on this basis, developed an “atomic extraction” strategy for catalyst design. By introducing an appropriate amount of tin (Sn), a promoter metal with a larger atomic radius and stronger bonding with platinum (Pt), into Pt-containing alloy nanoparticles, the researchers promoted the segregation of Pt atoms to the surface. This increased the exposure of Pt atoms on open surfaces from approximately 30% to nearly 100%, reaching the theoretical limit of catalytic material design.

This recognition highlights the originality, scientific significance, and potential industrial impact of the research, and underscores its importance in advancing the efficient utilization of precious metal resources and the development of sustainable chemical processes.
