Accounting for over 50% of global plastics, polyolefins possess a backbone of saturated C─C bonds that exhibit exceptional stability [1]. The improper disposal of polyolefin wastes has caused severe ecological damage, necessitating the development of recycling technologies [2].

1 Introduction Polyolefin wastes constitute over half of the total plastic waste, making recycling crucial for sustainable polymer industry development.[1, 2] Catalytic cracking of polyolefins is a promising upcycling route, especially to produce aromatics that are widely applied as platform molecules to synthesize pharmaceutical drugs, surfactants, and detergents.[3, 4] However, traditional methods involve harsh conditions to convert polyolefins to aromatics (temperatures above 500 °C or...
