Several techniques are employed to polish catalysts, including:
Thermal Treatment: Heating catalysts to high temperatures in controlled environments to remove impurities and improve crystallinity. Chemical Etching: Using chemical agents to selectively remove undesired materials from the catalyst surface. Mechanical Grinding: Physically abrading the catalyst surface to achieve a desired texture and particle size distribution. Plasma Treatment: Exposing catalysts to plasma to modify surface properties and enhance catalytic activity. Ultrasonic Cleaning: Using ultrasonic waves to remove contaminants from catalyst surfaces.
