style=\"color:red\">电催化</span>氧化引起了研究者的关注,高活性和稳定性及低价格的<span style=\"color:red\">电催化剂</span>的设计和制备一直是乙醇燃料电池的研究热点.本文采用复合电沉积方法制备了<span style=\"color:red\">Ni</span>和CeO2复合镀层,然后利用<span style=\"color:red\">Ni</span>置换铂前驱体中Pt的方法制备了纳米CeO2修饰的Pt/<span style=\"color:red\">Ni</span><span style=\"color:red\">电催化剂</span>(Pt/<span style=\"color:red\">Ni</span>-CeO2).采用X射线衍射(XRD)、扫描电子显微镜(SEM)及能谱仪(EDS)等手段表征了所制样品的组成和相结构、表面形貌及组成成份.XRD结果表明,所制Pt/<span style=\"color:red\">Ni</span><span style=\"color:red\">催化剂</span>主要是PtNi合金相结构.与Pt/<span style=\"color:red\">Ni</span>相比,Pt/<span style=\"color:red\">Ni</span>-CeO2<span style=\"color:red\">催化剂</span>的XRD峰强明显变弱,表明纳米CeO2修饰的Pt/<span style=\"color:red\">Ni</span><span style=\"color:red\">电催化剂</span>的结晶性较差或者其晶体颗粒较小.这可能是由于CeO2的共沉积阻止了<span style=\"color:red\">Ni</span>纳米颗粒的进一步生长或团聚.当电镀液中CeO2含量为50和100 mg/L时,所制Pt/<span style=\"color:red\">Ni</span>-CeO2<span style=\"color:red\">催化剂</span>样品Pt/NiCe1和Pt/NiCe2的XRD谱上未观察到CeO2相关的衍射峰,这主要可归因于<span style=\"color:red\">催化剂</span>中沉积的CeO2量少或其高度分散.随着电镀液中CeO2浓度进一步增大到200 mg/L时,在Pt/<span style=\"color:red\">Ni</span>-CeO2<span style=\"color:red\">催化剂</span>(Pt/NiCe4)的XRD谱上出现了CeO2相关的衍射峰.这表明采用复合电沉积-化学还原法可以成功制备CeO2修饰的Pt/<span style=\"color:red\">Ni</span><span style=\"color:red\">电催化剂</span>.SEM结果显示,所制<span style=\"color:red\">催化剂</span>都是由团聚状态的纳米颗粒组成,并且Pt/NiCe2表现出比Pt/<span style=\"color:red\">Ni</span>更开放的微结构,从而有利于反应物扩散至<span style=\"color:red\">催化剂</span>内部.该结果进一步表明共沉积的CeO2对所制Pt/<span style=\"color:red\">Ni</span><span style=\"color:red\">催化剂</span>微结构的影响.此外,EDS结果也证实成功制备了CeO2修饰的Pt/<span style=\"color:red\">Ni</span><span style=\"color:red\">电催化剂</span>.采用多次循环伏安、电流时间曲线和电化学阻抗谱(EIS)等手段研究了所制<span style=\"color:red\">电催化剂</span>的电化学性能.与Pt/<span style=\"color:red\">Ni</span>相比,Pt/<span style=\"color:red\">Ni</span>-CeO2<span style=\"color:red\">催化剂</span>表现出更好的<span style=\"color:red\">电催化</span>氧化乙醇活性和稳定性,这可能与CeO2的贮氧特性及其共沉积增大了电极的粗糙度有关.红外光谱测试结果表明,在CeO2修饰的Pt/<span style=\"color:red\">Ni</span><span style=\"color:red\">电催化剂</span><span style=\"color:red\">催化</span>氧化乙醇过程中,CH3COO?可能是乙醇氧化的主要产物.在所制<span style=\"color:red\">催化剂</span>中,CeO2含量影响其<span style=\"color:red\">电催化</span>氧化乙醇性能.循环伏安和电流时间曲线测试结果表明,随着<span style=\"color:red\">催化剂</span>中CeO2含量增大,<span style=\"color:red\">催化剂</span>活性先增加后减弱.电化学阻抗谱结果表明,随着CeO2含量增大,CeO2修饰的Pt/<span style=\"color:red\">Ni</span><span style=\"color:red\">电催化剂</span>的接触电阻先增大后变小再变大;而电荷转移电阻不断变小.在电解液中含有100 mg/L CeO2时所制<span style=\"color:red\">电催化剂</span>(Pt/NiCe2)具有最佳的<span style=\"color:red\">电催化</span>氧化乙醇活性和稳定性.这主要与CeO2的贮氧功能、Pt与CeO2/<span style=\"color:red\">Ni</span>间的相互作用和其较小的接触电阻和电荷转移电阻有关.该结果可为设计和制备低价格、高活性乙醇燃料电池中的<span style=\"color:red\">催化剂</span>提供思路.","authors":[{"authorName":"徐志花","id":"cc6d1a11-c403-4e77-8483-7b5161fea66e","originalAuthorName":"徐志花"},{"authorName":"饶丽霞","id":"eeb38ab1-9b99-43b7-8e77-3d5dacfc46b9","originalAuthorName":"饶丽霞"},{"authorName":"宋海燕","id":"bc22695d-362d-42ed-b134-b79d65845a34","originalAuthorName":"宋海燕"},{"authorName":"严朝雄","id":"5baadf64-2099-4eb6-98bd-32c2fabf0de4","originalAuthorName":"严朝雄"},{"authorName":"张利君","id":"f9b06c6c-5cf4-4a74-82fd-4cd6bd3f6f11","originalAuthorName":"张利君"},{"authorName":"杨水彬","id":"f0106d82-9652-4538-89fd-6e73cf39fcd7","originalAuthorName":"杨水彬"}],"doi":"10.1016/S1872-2067(16)62560-3","fpage":"305","id":"053a0056-d5e7-44d7-be72-d1761ecbf5fa","issue":"2","journal":{"abbrevTitle":"CHXB","coverImgSrc":"journal/img/cover/CHXB.jpg","id":"18","issnPpub":"0253-9837","publisherId":"CHXB","title":"催化学报
