Abstract Polyethylene (PE) is the most abundant plastic waste, and its conversion to hydrogen (H 2 ) offers a promising route for clean energy generation. However, PE decomposition typically requires high temperatures due strong chemical bonds, leading significant carbon emissions low H selectivity (theoretically less than 75 vol % after accounting further steam‐reforming reactions). Here, we report mechanocatalytic strategy that upcycles into high‐purity (99.4 %) with an exceptional recovery ratio of 98.5 (versus 15.7 via thermocatalysis), using manganese as catalyst at temperature 45 °C. This method achieves reaction rate 3 orders magnitude higher thermocatalysis. The marked improvement in mainly metal carbides formation induced by process, which does not catalyze hydrocarbons formation. work expected advance studies polyolefins net‐zero emissions.

Single-atom catalysts (SACs) have emerged as a research frontier in catalytic materials, distinguished by their unique atom-level dispersion, which significantly enhances activity, selectivity, and stability. SACs demonstrate substantial promise electrocatalysis applications, such fuel cells, CO2 reduction, hydrogen production, due to ability maximize utilization of active sites. However, the development efficient stable involves intricate design screening processes. In this work, artificial intelligence (AI), particularly machine learning (ML) neural networks (NNs), offers powerful tools for accelerating discovery optimization SACs. This review systematically discusses application AI technologies through four key stages: (1) Density functional theory (DFT) ab initio molecular dynamics (AIMD) simulations: DFT AIMD are used investigate mechanisms, with high-throughput applications expanding accessible datasets; (2) Regression models: ML regression models identify features that influence performance, streamlining selection promising materials; (3) NNs: NNs expedite known structural models, facilitating rapid assessment potential; (4) Generative adversarial (GANs): GANs enable prediction novel high-performance tailored specific requirements. work provides comprehensive overview current status insights recommendations future advancements field.
