Abstract

The main source of energy in the world is fossil fuels, but these can irreparably harm the environment. My research focuses on making a catalyst that is economical, efficient, and environmentally friendly. The oxygen reduction reaction is an important reaction for energy conversion systems, such as fuel cells. Onion-like carbon nanoparticles are used as a catalytic support for fuel cell applications due to its high conductivity and surface-to-volume ratio. The combination of carbon compounds with conductive polymers results in new materials and devices with possible practical applications. In my research we obtain onion-like carbon from nanodiamonds through a pyrolysis process. These particles are then polymerized using the aniline monomer to dope the OLCs with nitrogen. These particles are characterized by different characterization techniques such as Raman and Fourier transform infrared spectroscopy and scanning electron microscopy. After characterizing them, electrochemical experiments were carried out.

摘要

世界上主要的能源来源是化石燃料,但这些会对环境造成无法弥补的损害。我的研究重点是制造一种经济、高效且环保的催化剂。氧还原反应对于能量转换系统(如燃料电池)来说是一个重要反应。洋葱状碳纳米颗粒因其高导电性和表面积与体积比,被用作燃料电池应用的催化载体。碳化合物与导电聚合物的结合产生了具有实际应用可能性的新材料和新装置。在我的研究中,我们通过热解过程从纳米金刚石中获得洋葱状碳。然后使用苯胺单体使这些颗粒聚合,用氮对洋葱状碳进行掺杂。这些颗粒通过拉曼光谱、傅里叶变换红外光谱和扫描电子显微镜等不同表征技术进行表征。对它们进行表征后,开展了电化学实验。
