直接乙醇燃料电池阳极催化剂Pt-Ir-SnO2/C的制备与表征OA北大核心CSCDCSTPCD
Preparation and Characterization of Pt-Ir-SnO2/C Anode Catalyst for Direct Ethanol Fuel Cell
采用改良的Bönnemann法合成了一系列Pt/C、Pt-Ir/C、Pt-SnO2/C和Pt-Ir-SnO2/C阳极电催化剂.利用X射线衍射(XRD)、透射电子显微镜(TEM)以及X射线光电子能谱(XPS)对催化剂晶型结构、表面形貌、粒径尺寸和表面电子结构进行了表征.运用线性扫描伏安(LSV)、循环伏安(CV)和电流密度-时间(j-t)曲线进行电化学测试，研究了温度对乙醇电催化氧化活性的影响. XRD和TEM结果表明， Pt纳米粒子均为面心立…查看全部>>
Pt/C, Pt-Ir/C, Pt-SnO2/C, and Pt-Ir-SnO2/C anode electrocatalysts were prepared by an improved Bönnemann method. The crystal structure, surface morphology, particle size, and surface electronic structure were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). XRD and TEM revealed that Pt nanoparticles had a face-centered cubic structure, and that dispersions were relatively homogen…查看全部>>
