 The study compared three types of point-slash-C catalysts with different structural characteristics, including a conventional point-slash-vulcan catalyst with a particle size of 3 to 4 nanometers, two point-at-HGS catalysts with different particle sizes, 1 to 2 nanometers and 3 to 4 nanometers, and commercial materials. The researchers found that the point-at-HGS catalysts had higher activity than the conventional point-slash-vulcan catalyst, but lower stability. They also observed that the smaller particle size of the point-at-HGS catalysts resulted in greater stability, while larger particles led to increased activity. Additionally, the researchers noted that the thermal treatment of the catalysts affected both its activity and stability. In conclusion, the study suggests that the structural characteristics of the catalysts play a key role in determining their activity and stability. This article was authored by Joseph C.
