利用率逼近100%！我国科学家实现这一领域重大突破

Core Viewpoint - The research team from Tianjin University has developed an innovative "atomic extraction" strategy that significantly enhances the utilization of platinum in catalysts, achieving nearly 100% efficiency in catalytic reactions [1][4]. Group 1: Catalyst Innovation - The new catalyst developed using the "atomic extraction" strategy requires only 200 pounds to complete tasks that previously needed 1 ton, demonstrating extreme atomic economy [3]. - This catalyst shows superior activity and stability compared to existing commercial catalysts, even with a 90% reduction in platinum usage during high-temperature reactions such as propane dehydrogenation to propylene [3][4]. Group 2: Research Significance - The research led by Professor Gong Jinlong breaks away from traditional "single-atom dispersion" thinking, utilizing atomic-level alloy design and interface regulation to push the atomic utilization rate of precious metals to near theoretical limits [4].
