Synthesis and Characterization of Carbon Nanotube Supported Pt-Au Catalyst and Its Microwave Assisted N-Hexane Decomposition Measurements

Herein, CNT supported Pt and Pt-Au catalysts were carefully synthesized via NaBH4 reduction method. Pt-Au catalysts were obtained at varying ratios. For all of these CNT supported Pt and Pt-Au catalysts, BET, EDX, and XRD measurements were performed. The atomic ratio of the catalyst was obtained by EDX analysis. Surface area was defined via BET and crystal structure was examined by XRD. For microwave assisted n-hexane reforming measurements, microwave reactor was used to investigate the decomposition of n-hexane on CNT supported bimetallic Pt-Au catalysts. After applying microwave heating during the reaction time, the volume change is defined and read out. As a result, it was observed that Pt-Au catalysts prepared at 50:50 atomic ratio gives the best catalytic activity.
