废弃塑料变氢气（创新汇）

Core Viewpoint - A research team from Seoul National University has developed a method to continuously produce hydrogen from plastic waste using a novel structural reactor that enhances catalytic activity and stability through the use of nanocomposite materials [1][3]. Group 1: Technology and Innovation - The new method allows for hydrogen production from plastic waste under natural sunlight, eliminating the need for high temperatures and reducing energy consumption and carbon emissions [1][2]. - The innovative structural reactor design protects the catalyst from corrosive alkaline solutions, significantly improving hydrogen production efficiency by approximately 3-5 times compared to previous systems [3]. - The experimental results show that the system can produce up to 0.906 liters of hydrogen per square meter per day and can operate stably for over 60 days [3]. Group 2: Market Potential and Applications - The technology is particularly suitable for distributed processing of plastic waste in outdoor environments, addressing the global challenge of plastic pollution and contributing to green hydrogen production [3][4]. - Current applications are primarily focused on degrading PET plastics, with some effectiveness on PLA plastics, but challenges remain in processing more widely used plastics like PE and PP [3][4]. - Future research will need to focus on developing high-performance catalysts capable of effectively degrading PE and PP plastics under low-carbon and low-temperature conditions [3][4].
