Опубликована: Янв. 8, 2025

Abstract The escalating crisis of oceanic plastic pollution demands innovative and effective strategies for resolution. Photocatalysis offers a sustainable, green, energy‐efficient approach the upcycling waste into fuels value‐added chemicals. In this study, an atomically engineered GeS NS/ZnIn₂S₄ photocatalyst is employed to directly transform raw polyethylene terephthalate (PET), ubiquitous plastic, variety organic chemicals (13 917 µmol g⁻¹) using Earth's most abundant resources: sunlight, seawater, air. Advanced ex situ in characterization analyses reveal that sulfur vacancies (Vs) electrolyte‐assisted polarization effect seawater play crucial roles trapping photogenerated electrons accelerating charge carrier separation, respectively. These effects significantly enhance photocatalytic efficiency improve oxidative reactions. This research introduces methodology accounts real‐world conditions upcycling, utilizing natural resources paving way further exploration area.

Anti-defect Engineering of Crystalline g-C₃N₄ Nanostructures for Efficient Photocatalytic In Situ H₂O₂ Production

ACS Applied Nano Materials, Год журнала: 2023, Номер 6(5), С. 3927 - 3935

Опубликована: Фев. 27, 2023

How to realize on-site small-scale production and sustainable consumption of H2O2 is the focus attention this study. Photocatalysis technology can just meet demand, g-C3N4 one most popular catalysts employed. However, numerous defects in nanostructure seriously inhibit its catalytic activity, which act as recombination centers photogenerated carriers. Herein, we propose an anti-defect engineering strategy tailor a highly crystalline for efficient photocatalytic situ production, be further cascaded wastewater remediation. High-resolution transmission electron microscopy spin-resonance spectroscopy results demonstrate that successfully fabricated with extremely low defect concentrations. Transient surface photovoltage data shows exhibits rapid charge separation transfer slow decay. Therefore, activity significantly promoted by eliminating construct structure. Especially, prepared thiourea (CNT) maximum 2.48 mmol g–1 h–1 apparent quantum efficiency 22% (λ = 400 nm), along excellent cascade tetracycline removal effect. This work provides regulate crystal structure catalyst enhanced activity.
