Abstract

The design of UV-visible light active photocatalysts for organic pollutant removal is a challenging task. Herein, we have developed an LED light active ZnO-embedded S-doped g-CN (SCN) heterojunction by a facile sol-gel assisted calcination method. The heterojunction between ZnO and SCN nanoparticles generates a Z-scheme photocatalyst, which helps to separate the photo-induced charge carriers in the opposite direction, and is beneficial for more visible light absorption for photocatalytic dye degradation. The composite heterojunction shows better photocatalytic redox in comparison with pristine nanomaterials. The enhanced degradation efficiency is attributed to the high production rate of ˙OH (hydroxyl) radicals during the photocatalysis process, which is analyzed by the TA test and elemental trapping experiment. Hence, we hope that this Z-scheme heterojunction provides a new way to develop UV-visible light active photocatalysts for environmental remediation applications.

摘要

设计用于去除有机污染物的紫外-可见光活性光催化剂是一项具有挑战性的任务。在此，我们通过一种简便的溶胶-凝胶辅助煅烧方法，开发了一种LED光活性的ZnO嵌入S掺杂g-CN（SCN）异质结。ZnO和SCN纳米颗粒之间的异质结产生了一种Z型光催化剂，有助于将光生电荷载流子向相反方向分离，并且有利于在光催化染料降解中吸收更多可见光。与原始纳米材料相比，复合异质结表现出更好的光催化氧化还原性能。降解效率的提高归因于光催化过程中˙OH（羟基）自由基的高产率，这通过TA测试和元素捕获实验进行了分析。因此，我们希望这种Z型异质结为开发用于环境修复应用的紫外-可见光活性光催化剂提供一种新途径。
