Control over Charge Separation by Imine Structural Isomerization in Covalent Organic Frameworks with Implications on CO 2 Photoreduction

Daniel Streater, Eric R. Kennehan, Denan Wang, Christian Fiankor et autres

Two-dimensional covalent organic frameworks (COFs) are an emerging class of photocatalytic materials for solar energy conversion. In this work, we report a pair of structurally isomeric COFs with reversed imine bond directions, which leads to drastic differences in their physical properties, photophysical …

Electrochemical Gelation of Metal Chalcogenide Quantum Dots: Applications in Gas Sensing and Photocatalysis

Xin Geng, Daohua Liu, Chathuranga C. Hewa‐Rahinduwage, Stephanie L. Brock et autres

Conspectus Metal chalcogenide quantum dots (QDs) are prized for their unique and functional properties, associated with both intrinsic (quantum confinement) and extrinsic (high surface area) effects, as dictated by their size, shape, and surface characteristics. Thus, they have considerable promise for diverse …

超声/Fe 0 /EDTA体系对印染污泥中多环芳烃的降解

满小媛, Man Xiaoyuan, 宁寻安, Ning Xun'an et autres

Fe0/EDTA类芬顿体系能产生氧化能力极强的羟基自由基（·OH），已被广泛应用于有机污染物的去除.提高·OH的生成速率和浓度是高效降解有机污染物的关键.因此，本文利用超声/Fe0/EDTA体系处理印染污泥，探讨了不同反应参数对体系中产生·OH的影响，考察了该体系对印染污泥中多环芳烃（PAHs）的去除效果.结果表明，在pH为3.0，超声功率为540 W，Fe0投加量为15 g·L-1，EDTA浓度为2.0 mmol·L-1的最佳条件下，·OH浓度高达862 μmol·L-1.印染污泥中的铁絮凝剂可作为超声/Fe0/EDTA体系中Fe2+和Fe3+的来源，促使该体系循环产生H2O2和·OH.超声/Fe0/EDTA体系产生的·OH能快速有效地降解印染污泥中的PAHs，∑16PAHs的平均去除率达到77%，同时有机质含量下降了10.1%.
