Abstract

When spacecraft operate in space, most organic materials will release small molecular hydrocarbons and large molecular organic gases due to gas evolution effect under high vacuum conditions. These gases can deposit on the surface of spacecraft, adversely affecting its performance. Adsorption becomes the first choice for removing such organic pollutants in the space environment. Zeolite material has a stable and dense porous structure, and has been widely used in the field of pollution adsorption. In this work, Al₂O₃ was deposited on the surfaces of 5A zeolite for the first time by atomic layer deposition (ALD) technology. As a result, the adsorption performance of Al₂O₃ coated 5A zeolite (zeolite@ Al₂O₃) was significantly modified. The corresponding adsorption process was clarified via adsorption kinetics study.
