重大突破！利用率逼近100%

Core Insights - The article highlights a significant breakthrough by Chinese scientists in catalyst technology, achieving nearly 100% utilization of precious metals in catalysts, which are essential for chemical reactions [1][4]. Group 1: Catalyst Innovation - The research team from Tianjin University has developed a novel "atomic extraction" strategy that allows all platinum atoms, crucial for catalysis, to be extracted to the surface for participation in catalytic reactions [1][4]. - The newly developed catalyst demonstrates extreme atomic economy, requiring only 200 pounds to accomplish tasks that previously needed 1 ton [3]. Group 2: Performance and Efficiency - In high-temperature and harsh reactions, such as propane dehydrogenation to propylene, the new catalyst shows superior activity and stability compared to existing commercial catalysts, even with a 90% reduction in platinum usage [3][4]. - The research led by Professor Gong Jinlong breaks away from traditional "dispersed single atom" thinking, utilizing atomic-level alloy design and interface regulation to push the atomic utilization rate of precious metals close to theoretical limits [4].
