Abstract

The invention belongs to the technical field of preparation of porous composite materials, and provides a slurry state synthetic method for a porous composite framework material. The mass ratio of a solvent to a solid reactant is controlled, so that the reactant is at different saturations, an inorganic-organic composite framework material is obtained through heating in a sealed container, and thecrystal size and distribution of the composite framework material are regulated and controlled. Under a room temperature, an inorganic metal source is dispersed into the solvent, and then mixed witha polycarboxylic acid organic compound to form a slurry material, and the slurry material is sealed in a self-pressurized reaction kettle, the obtained material is heated to 70-170 DEG C, a reaction is performed for 0.5-240 hours, drying is performed at the room temperature, and therefore the porous composite framework material is obtained. According to the invention, the crystal size is controllable, and the method provides a novel synthetic route for controlling the particle size of the composite framework material; the yield is higher, washing is not needed, the operating costs are low, theoperation is easy, the emission is zero, the method is green, environmentally friendly, economical and practicable, and the large-scale intensive production is easy to realize; and the obtained large-particle composite framework material has a higher adsorption capacity in the gas adsorption aspect.
