We investigated the structural and optical properties of the hierarchically integrated zinc oxide (ZnO) branched submicrorods on carbon fibers (ZOCF) by scanning/transmission electron microscopy, X-ray diffraction, and photoluminescence (PL) measurements. The ZnO submicrorods were facilely synthesized by an electrochemical deposition method on polyacrylonitrile-based carbon fiber sheets used as a substrate. After coating the ZnO seed layer on the surface of the carbon fibers, ZnO submicrorods were densely grown on the nuclei sites of the seed layer. The prepared ZOCF samples exhibited high crystallinity and good PL properties. A feasibility for environmental application in Pb(II) removal from aqueous solutions was also studied. The ZOCF adsorbent exhibited an excellent maximum adsorption capacity of 245.07 mg g-1, which could be practically used in Pb(II) removal from water. These fabricated ZOCFs are potentially useful for multifunctional and environmental devices.
我们通过扫描/透射电子显微镜、X 射线衍射和光致发光（PL）测量研究了分层集成在碳纤维（ZOCF）上的氧化锌（ZnO）树枝状亚微米棒的结构和光学性质。通过在用作基底的聚丙烯腈基碳纤维片上的电化学沉积方法，容易地合成了 ZnO 亚微米棒。在碳纤维表面涂覆 ZnO 种子层后，ZnO 亚微米棒在种子层的核位点上密集生长。所制备的 ZOCF 样品表现出高结晶度和良好的 PL 性能。还研究了其在水溶液中去除 Pb(II)的环境应用的可行性。ZOCF 吸附剂表现出 245.07mg/g-1 的优异最大吸附容量，可实际用于从水中去除 Pb(II)。这些制备的 ZOCF 有望用于多功能和环境设备。
