Abstract The escalating accumulation of plastic waste has been developed into a formidable global environmental challenge. Traditional disposal methods such as landfilling and incineration not only exacerbate degradation by releasing harmful chemicals greenhouse gases, but also squander finite resources that could otherwise be recycled or repurposed. Upcycling is kind recycling technology converts high‐value helps to avoid resource pollution. Electrocatalytic upcycling emerges novel distinguished its mild operational conditions, high transformation efficiency product selectivity. This review commences with an overview the employed in management respective advantages inherent limitations are delineated. different types upcycled electrocatalytic strategy then discussed process examined together mechanisms underlying upcycling. Furthermore, structure‐activity relationships between electrocatalysts performance elucidated. aims furnish readers comprehensive understanding techniques for provide guidance design towards efficient transformation.

Dual-atom catalysts (DACs) have garnered significant interest due to their high atom utilization and synergistic catalysis. However, developing a precise synthetic method for DACs comprehending the underlying catalytic mechanisms remain challenging. In this study, we employ photoinduced anchoring strategy precisely synthesize PtCo DAC on graphitic carbon nitride (CN). A Co was anchored CN through lone-pair electrons of nitrogen. Upon light irradiation, photoelectrons gathering at site can anchor Pt metal ions nearby, accurately facilitating formation heteronuclear DACs. The demonstrates remarkably H2 generation rate from ammonia borane (AB) hydrolysis, with TOF 3130 molH2 molPt–1 min–1 298 K. This value is approximately 3.2 times higher than that single-atom photocatalyst. Importantly, shows good stability, achieving turnover number as 307,982 room temperature. experimental theoretical calculation results demonstrate synergy between optimizes adsorption energy AB molecules while reducing barrier rate-determining step, thus accelerating evolution hydrolysis. Additionally, introduced species stabilize active sites by enhancing stability Pt–N bond, preventing leaching, aggregation, deactivation. excellent performance, low cost in work open new prospects practical application hydrogen production.
