X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Scanning Electron Microscopy (SEM)and Transmission Electron Microscopy (TEM) are used to analyze the compositions and the micromorphology of the samples. And the electrocatalytic activities are tested by a CHI workstation. It is shown that the use of CFs alleviates the problem of easy agglomeration of Co nanoparticles (Co NPs), which is conducive to achieve a maximum exposure of active sites. When used as a hydrogen evolution catalyst, only a low overpotential of 250 mV is required for obtaining a current density of 10 mA cm-2 and the catalyst could also maintain its stability for a time as long as 15 h., authors=YANG Ning, LI Caicai, SUN Qingfeng, authorsList=YANG Ning, LI Caicai, SUN Qingfeng, authorCompany=School of Engineering, Zhejiang A&F University, Hangzhou 311300, China,

articleAbstract=以木质纤维素为基体，采用浸渍、高温碳化的方法制备了木质碳纤维负载的钴纳米颗粒（Co/CFs）电催化剂。利用X射线衍射（XRD）、X射线光电子能谱（XPS）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）等对样品的化学组成和微观形貌进行了表征分析，并借助电化学工作站测试了样品的电催化析氢性能。结果表明，CFs的引入有效缓解了Co纳米颗粒（Co NPs）易团聚的问题，有利于实现活性位点的最大程度暴露。当Co/CFs用作析氢催化剂，达到10 mA·cm^-2的电流密度时需要的过电位仅为250 mV，并可保持长达15 h的催化稳定性。, authors=杨宁, 李彩彩, 孙庆丰, authorsList=杨宁, 李彩彩, 孙庆丰, authorCompany=浙江农林大学工程学院, 杭州 311300,
