  "abstract": "Recovery of precious metals from waste has high social and economic value, but in practice, recycling is often inefficient due to limits in technologies and materials. Here we show a group of materials-two-dimensional (2D) metallic 1 T/1 T′ phase transition metal dichalcogenides (TMDs, MoS 2 , WS 2 , TaS 2 , and TiS 2 )-that allows for efficient, selective, and scalable extraction of valuable gold (Au) from leaching solutions of end-of-life electronics. The materials exhibit rapid kinetics, delivering an impressive 99.99% extraction efficiency of Au 3+ in merely 0.25 min. Furthermore, they showcase strong selectivity for Au 3+ adsorption, featuring a distribution coefficient (K d ) 5-6 orders of magnitude higher than that of other competitive cations (Cu 2+ , K + , Ni 2+ , Na + , Zn 2+ , Ca 2+ , and Mg 2+ ). Amongst, TiS 2 exhibits an unprecedented extraction capacity of 9093 mg⋅g -1 toward Au 3+ , which is approximately 1 order of magnitude higher than most other benchmark adsorbents (silver-organic frameworks). Importantly, through batch production of TiS 2 nanosheets (5 g) and subsequent membranes fabrication for gold extraction, we demonstrated 0.15 g gold (23.8 Karat) recovery by treating 30 discarded central processing units (CPUs). Our work provides a foundation for the efficient and selective recovery of highvalue metals from waste, contributing to a sustainable and circular economy.\n\nGlobal E-waste Monitor 2020 expects a substantial surge in global electronic waste (e-waste) from 9 million tons in 2020 to 75 million tons by 2030 1 . E-waste still contains metals (gold, for example) 2,3 that are often critical elements with high economic value. Their recycling is thus critical to a circular economy 4-10 . Typically, the high-value metals can be precipitated from the leaching solutions of e-waste by adding chemicals or selectively extracted using a more soluble solvent 11-13 . The target metals can also be selectively adsorbed by an adsorbent or ion exchange resin 14 .
