新型催化剂贵金属利用率近100%

Core Insights - The research team from Tianjin University has developed an innovative "atomic extraction" strategy that significantly enhances the utilization of platinum atoms in catalytic reactions, achieving nearly 100% efficiency [1][2] - This advancement addresses the low atomic utilization rates of traditional catalysts, particularly in the critical process of propane dehydrogenation for propylene production, which is essential for various industries [1][2] Group 1: Technological Innovation - The "atomic extraction" technology allows for the selective attraction of platinum atoms to the surface of catalyst particles, thereby increasing their availability for catalytic reactions [1] - This method contrasts with traditional catalysts, where platinum atoms tend to aggregate into larger particles, resulting in many atoms being buried and inactive [1] Group 2: Economic Impact - The new catalyst technology reduces the amount of catalyst needed from 1 ton to just 200 jin (approximately 100 kg), showcasing extreme atomic economy [2] - In high-temperature reactions like propane dehydrogenation, the new catalyst demonstrates superior activity and stability while reducing platinum usage by 90% compared to existing commercial catalysts [2] Group 3: Industry Relevance - Propylene is one of the most produced chemical products globally, with China projected to account for one-third of global propylene production by 2024, generating over 600 billion RMB [1] - Approximately two-thirds of propane dehydrogenation processes rely on precious metal catalysts, highlighting the importance of improving catalyst efficiency for sustainable industry development [1]
