Recycling of noble metal from waste materials, namely from electronic wastes (e‐waste), spent catalyst, and industrial wastewater, is attracting growing attention due to the scarcity, economic importance, and criticality of those noble metals. Traditional techniques reported to date require toxic reagent and strict extraction conditions, which deeply hinders the development of precious metal recovery in complex environments. Here, an approach is proposed that uses flexible metallic transition metal dichalcogenide (TMD) paper, which provides abundant active sites for spontaneous adsorption and reduction of noble metal ions, as an Alchemy‐inspired template to recover noble metal in an efficient and green way without the aid of reductant and heating. The metallic TMD (MoS₂, WS₂) paper is shown to rapidly extract five noble metal ions (Au, Pd, Pt, Ag, and Ru) from complex samples containing various interferents. This unique property endows the metallic TMD paper with gifted ability in extracting gold from e‐waste, and recovering platinum group metals (palladium and platinum) from spent catalysts, which provides a blueprint for the design of next‐generation green platforms for noble metal regeneration.

炼金术自发地回收贵金属的绿皮书。

从废料中回收贵金属，即电子废物（电子废物），废催化剂和工业废水，由于这些贵金属的稀缺性，经济重要性和重要性而受到越来越多的关注。迄今报道的传统技术需要有毒的试剂和严格的提取条件，这严重阻碍了复杂环境中贵金属回收的发展。在这里，提出了一种方法，该方法使用可弯曲的金属过渡金属二硫化氢（TMD）纸作为炼金术的模板，提供了丰富的活性位点，可以自发吸附和还原贵金属离子，可以高效，绿色地回收贵金属，而无需化学还原剂和加热的帮助。金属TMD（MoS ₂，WS ₂）表明，纸可以从含有各种干扰物的复杂样品中快速提取出五种贵金属离子（Au，Pd，Pt，Ag和Ru）。这种独特的性能使金属TMD纸具有从电子废物中提取金并从废催化剂中回收铂族金属（钯和铂）的能力，这为设计用于贵金属再生的下一代绿色平台提供了蓝图。 。
