Abstract The efficient separation of photocarriers and facile generation superoxide radicals are crucial for enhancing the performance photocatalysts in selectively photo‐oxidizing 5‐hydroxymethylfurfural (HMF) into 2,5‐diformylfuran (DFF). Herein, a ZnIn 2 S 4 /CeO composite with S‐scheme heterojunction sulfur vacancies (S V ) is successfully developed through one‐step hydrothermal method. optimal catalyst ‐ZnIn exhibits excellent catalytic activity 100% conversion HMF 96.1% selectivity DFF 80 min under ambient conditions, production rate up to 952.6 µmol g −1 h . Intriguingly, remains significant even when concentration increased from 8 100 mм. Experimental theoretical investigations discover that synergistic effect contribute activation oxygen, which facilitate radicals, thus boosting oxidation reactions.

Published: Sept. 14, 2024

Cu interconnect chemical mechanical polishing (CMP) technology has been continuously evolving, leading to increasingly stringent post-CMP cleaning requirements. To address the environmental pollution caused by traditional solutions, we have explored use of photocatalytic processes remove citric acid, which is a commonly used complexing agent for CMP. In this study, CeO2 abrasives, characterized hardness 5.5, are extensively employed in Importantly, also exhibits suitable band structure with gap 2.27 eV, enabling it photocatalytically Additionally, integration H2O2, an essential oxidant CMP, enhances degradation efficiency. The research indicates that removal rate single-phase was 1.78 mmol/g/h and efficiency increased 40% addition attributed hydroxyl radicals generated from Fenton-like reaction between H2O2 CeO2. These findings highlight potential improve organic contaminant cleaning, offering more sustainable alternative conventional practices.
