Published: July 26, 2024

Excessive production of waste polyethylene terephthalate (PET) poses an ecological challenge, which necessitates developing technologies to extract the values from end-of-life PET. Upcycling has proven effective in addressing low profitability current recycling strategies, yet existing upcycling operate under energy-intensive conditions. Here we report a cascade strategy steer transformation PET into glycolate overall yield 92.6% ambient The approach involves setting up robust hydrolase with 95.6% depolymerization ethylene glycol (EG) monomer within 12 h, followed by electrochemical process initiated CO-tolerant Pd/Ni(OH)

Published: April 18, 2024

In recent years, preparing precious metal catalysts with a controllable morphology has become hot research topic for researchers. this study, monodispersed palladium (Pd) nanoparticles (NP) and ultrathin Pd twisty nanowire networks (TNN) were synthesized in solvothermal system using N,N-dimethylformamide (DMF) oleylamine (OAm) as solvents, Transmission electron microscopy (TEM) images reveal the successful synthesis of TNN microstructures. Electrochemical data show that current densities Pd–NP Pd–TNN ethanol oxidation reaction (EOR) reach 1878 mA mg–1 1765 mg–1, respectively. Compared to commercial Pd/C, exhibit better catalytic stability, lower transfer barriers, more resistance catalyst poisoning. Temperature, pH value, concentration are all favorable EOR. According experimental data, mechanism enhanced electrocatalytic activity is discussed. This paper presents method stabilized structures develop Pd-based reactions.
