摘要： A zeolite membrane complex includes a porous support, and a zeolite membrane formed on the support. The zeolite membrane includes a zeolite crystal phase constituted by a plurality of zeolite crystals, and a dense grain boundary phase, which is a region between the plurality of zeolite crystals. A density of at least part of the grain boundary phase is smaller than a density of the zeolite crystal phase. A width of the grain boundary phase is 2 nm or more and 10 nm or less. Accordingly, it is possible to realize high permeability and high separating performance, and high durability of the zeolite membrane.

摘要： There is disclosed a ceramic separation membrane. This ceramic separation membrane includes a porous substrate, and a separation layer formed on the substrate. The separation layer is a laminate having an outermost layer positioned on the most surface side, and a base layer positioned in a lower layer than the outermost layer and made of zeolite. The outermost layer is a layer made of a siliceous material containing 90 mol % or more of silica, an organic material-containing amorphous silica material having a Si—Cn—Si (wherein n is 1 or 2) bond and a Si/C ratio of 0.5 to 2, or a carbonaceous material containing 90 mass % or more of carbon. The outermost layer is different from the base layer.

摘要： The organic-inorganic composite of the present invention includes an organic compound having a carbonyl group, an inorganic compound containing a metal component, and a silver component. The ratio of the number of metal atoms in the inorganic compound to the number of carbon atoms in the organic compound is from 0.04 to 1.60, and the ratio of the number of silver atoms in the silver component to the number of carbon atoms in the organic compound is from 0.07 to 0.55. The organic-inorganic composite may include, for example, an inorganic compound having a metal matrix structure containing a metal M and oxygen, an organic compound having a carbonyl group, and silver ions. The carbonyl group is bonded to a side chain R1 of the organic compound and has an end group R2.

摘要： Provided is a separation membrane manufacturing method capable of easily manufacturing a dense separation membrane. The separation membrane manufacturing method comprises a membrane forming step of forming a separation membrane precursor containing a separation membrane precursor solution on the surface of cells formed in a porous monolith substrate; and a drying step of performing ventilation drying by passing hot air through the cells having the separation membrane precursor in the monolith substrate to dry the separation membrane precursor. During the ventilation drying in the drying step, the temperature of the monolith substrate having the separation membrane precursor is raised to 90° C. within 15 minutes from the start of the passing of the hot air at such a rate of temperature rise that an average rate of temperature rise is 7° C./min or more from the start of the passing of the hot air until the temperature reaches 90° C.
