The present study focuses on the effects of nitrogen (N) ion implantation in vertically aligned ZnO nanorod arrays (NRAs) and the photocatalytic degradation of acetaminophen. The X-ray diffraction of these NRAs exhibit a wurtzite structure with a predominant (002) diffraction peak that shifts slightly after N-ion implantation. The field emission scanning electron microscopic images of as-prepared NRAs show a length of ∼4 μm and diameter of ∼150 nm. UV-visible spectroscopy reveals that the band gap of pristine ZnO NRAs decreases from 3.2 to 2.18 eV after N-ion implantation. Under visible irradiation, the N-ion-implanted ZnO catalyst exhibits significant enhancement of the photocatalytic degradation of acetaminophen from 60.0 to 98.46% for 120 min.
本研究聚焦于氮（N）离子注入垂直排列的氧化锌纳米棒阵列（NRAs）的效果以及对乙酰氨基酚的光催化降解。这些纳米棒阵列的X射线衍射显示出纤锌矿结构，其主要的（002）衍射峰在氮离子注入后略有移动。所制备的纳米棒阵列的场发射扫描电子显微镜图像显示其长度约为4μm，直径约为150nm。紫外可见光谱表明，氮离子注入后，原始氧化锌纳米棒阵列的带隙从3.2eV降至2.18eV。在可见光照射下，氮离子注入的氧化锌催化剂对乙酰氨基酚的光催化降解在120分钟内从60.0%显著提高到98.46%。
