利用率逼近100%!我国科学家实现这一领域重大突破

Core Insights - Catalysts are referred to as the "heart" of modern chemical industry, playing an irreplaceable role in accelerating various chemical reactions [1] - Precious metals are key components of catalysts, and their usage is crucial for energy-saving and efficiency in chemical processes [1] Group 1: Research Innovation - Tianjin University’s new strategy, termed "atomic extraction," allows for the complete extraction of platinum atoms to the surface for catalytic reactions, achieving nearly 100% utilization [1] - The catalyst developed using this strategy requires only 200 pounds to complete tasks that previously needed 1 ton, demonstrating extreme atomic economy [1] Group 2: Performance and Stability - In high-temperature and harsh reactions, such as propane dehydrogenation to propylene, the new catalyst shows superior activity and stability compared to current commercial catalysts, even with a 90% reduction in platinum usage [1] Group 3: Research Leadership - The research team is led by Professor Gong Jinlong, who emphasizes that their work breaks away from traditional "dispersed single atom" thinking, paving new paths for the design of efficient catalysts through atomic-level alloy design and interface regulation [1]
