重大突破！我国科学家实现催化剂中贵金属利用率逼近100%

Core Insights - The article discusses a breakthrough in catalyst technology by Tianjin University, focusing on a new strategy called "atomic extraction" that enhances the utilization of precious metals in catalytic processes [1][4]. Group 1: Catalyst Technology - Catalysts are essential in modern chemical industries, with precious metals being key components that significantly affect energy efficiency in chemical processes [1]. - Traditional catalytic reactions often suffer from low atomic utilization due to the aggregation of precious metal atoms into larger particles, which limits their effectiveness [3]. - The new "atomic extraction" technology developed by Tianjin University allows for nearly 100% utilization of platinum atoms by drawing them to the surface for catalytic reactions [4]. Group 2: Economic Impact - Propylene, produced through propane dehydrogenation, is a major chemical product with China expected to account for one-third of global production in 2024, generating over 600 billion RMB in total output [3]. - The new catalyst technology reduces the amount of platinum needed by 90%, achieving significant cost savings and efficiency improvements in high-temperature reactions [8]. Group 3: Research and Collaboration - The research team, led by Professor Gong Jinlong, has spent nearly a decade developing this innovative technology, which is inspired by extraction unit operations in chemical engineering [4]. - The study represents a significant advancement in catalyst technology, positioning Chinese research teams at the forefront of global catalyst development and supporting energy security and green transformation efforts [8].
