▎ 摘  要

The development of efficient catalysts for application in the Fischer-Tropsch synthesis (FTS) is of great relevance. Supported cobalt is preferred, and the choice of support is critical to the success of the process. For this, graphene materials have grown in interest due to their unique and appreciable characteristics. Thus, this study aims to perform a systematic review of previous studies which evaluated the use of graphene materials as support means for cobalt FTS catalysts. Twelve studies from the last five years were selected for extraction and analysis of results. The main parameters that influenced the catalytic activity of FTS catalysts were discussed, such as the type of support used, the chosen preparation method, and the graphene functionalization method. The results showed that the catalysts synthesized from different types of graphene support obtained CO conversion rates between 20 and 86.9% and high selectivity for C5 + compounds in the gasoline range. Furthermore, the functionalization of graphene with functional groups and pretreatment with nitric acid was essential to adjust the metal-support interaction and ensure catalytic efficiency. The preparation of catalysts involves a series of parameters that must be considered to ensure that the Co/C ratio produces an optimal particle size, consequently presenting better efficiency. Finally, this work highlights the potential to be explored of graphene materials used as support for FTS catalysts and their promising results.
