The paper attempts to summarize recent significant progress in synthesis of microporous and dense inorganic membranes with the help of the results obtained in the author's laboratory or reported in the literature. The paper first reviews several methods for synthesis of microporous amorphous and polycrystalline (zeolite) inorganic membranes and their major characteristics. These microporous membranes exhibit fascinating gas permeation and separation properties. The paper also reviews equally impressive progress on oxygen semipermeable dense oxygen ionic-conducting ceramic membranes and hydrogen semipermeable metal membranes. Searching for better membrane materials, developing effective membrane synthesis methods, and improving chemical and structural stability of the current membrane materials will continue to be the focus of active research in these areas. Specific examples of the future research include synthesis of micro and mesoporous polycrystalline inorganic membranes with oriented pores and development of more effective dense proton-conducting ceramic membranes for high temperature hydrogen separation and membrane reactor applications.
