Guided by the concept of green chemical engineering,inorganic membranes have emerged in the field of chemical separation due to their excellent chemical stability,high temperature resistance,narrow pore size distribution,and high separation efficiency.This paper provided a detailed discussion on the research progress,characteristics,application areas,and future development trends of several popular inorganic membrane materials,including inorganic carbon membranes,inorganic ceramic oxygen-permeable membranes,and inorganic zeolite membranes.It focused on several key factors closely related to the separation performance of these inorganic membranes,including membrane structure composition,optimization of preparation processes,and precursor selection.It emphasized that the formation of membrane defects during the synthesis process was one of the major challenges in the large-scale production of inorganic membranes,and reviewed the latest methods in the field of inorganic membranes to suppress defects.
