Solar-driven reforming of plastics offers a simple and low-energy means to turn waste into H₂. Here, we report the efficient photoreforming of three commonly produced polymers – polylactic acid, polyethylene terephthalate (PET) and polyurethane – using inexpensive CdS/CdO_x quantum dots in alkaline aqueous solution. This process operates under ambient temperature and pressure, generates pure H₂ and converts the waste polymer into organic products such as formate, acetate and pyruvate. We further validate the real-world applicability of the system by converting a PET water bottle into H₂. This is the first demonstration of visible light-driven, noble metal-free photoreforming of plastic.

塑料废料作为太阳能驱动的H ₂世代的原料† ‡

太阳能驱动的塑料重整提供了一种简单且低能耗的方式，可以将废物转化为H ₂。在这里，我们报告了在碱性水溶液中使用廉价的CdS / CdO _x量子点对三种常用的聚合物-聚乳酸，聚对苯二甲酸乙二醇酯（PET）和聚氨酯进行了有效的光重整。该过程在环境温度和压力下操作，生成纯H ₂并将废聚合物转化为有机产物，例如甲酸盐，乙酸盐和丙酮酸盐。通过将PET水壶转换为H _2，我们进一步验证了该系统在现实世界中的适用性。这是可见光驱动的无贵金属塑料光固化的首次演示。
