摘要

本研究包括一种新型富勒烯储氢复合材料的合成。本研究的第一步是利用C60型富勒烯制备其与纳米硒(Se Nps)的复合材料。该合成方法新颖,以抗坏血酸为还原剂,在750瓦下通过超声合成富勒烯-硒纳米复合材料,将硒离子转化为纳米硒。采用XRD、SEM、TEM等技术对制备的复合材料的组成、尺寸和形貌进行了表征。SEM和TEM的表征结果表明,在棒状纳米颗粒上形成了球状结构,证明了所需纳米复合材料的形成。此外,XRD谱图显示了高纯度的富勒烯和硒纳米粒子峰的存在。从该纳米复合材料在氢能领域的应用中认识到其重要性。在77,173,223和273 K和0-90 bar的条件下进行了研究,研究证实了55 bar条件下的物理吸附,其焓为0.13 KJ/(mol H2),熵为0.70 J/mol H2,储气量为4.1 wt%。K。

Thermodynamic Parameters (Enthalpy and Entropy) of Hydrogen Storage in Ultrasound-Assisted Synthesized Selenium Decorated Fullerene

This study includes the synthesis of a novel fullerene composite for hydrogen storage application. In the first step of this work the fullerene of the type C60 was used to prepare its composite with selenium nanoparticles (Se Nps). The synthesis method was novel as it includes the synthesis of fullerene-Se nanocomposite via ultrasound at 750 W using ascorbic acid as reducing agent to convert selenium ion into selenium nanoparticles. Different techniques (XRD, SEM, TEM) were used to diagnose the composition, size and morphology of the prepared composite. The characterization results from SEM and TEM demonstrate the formation of sphere-like structures decorated on rod nanoparticles, proving the formation of required nanocomposite. Moreover, the XRD pattern demonstrates the existence of fullerene and selenium nanoparticles peaks with high purity. The important of this nanocomposite was comprehended from the using it in the hydrogen energy application. The study was conducted at 77, 173, 223 and 273 K and 0–90 bar and the study proves the physical adsorption at 55 bar as it showed 4.1 wt% storage with enthalpy of 0.13 KJ/(mol H2) and entropy of 0.70 J/mol H2. K.
