AI Technical Summary
Existing methods for producing porous materials with a co-continuous structure fail to achieve large most frequent pore sizes for micropores and coarse pores, leading to limitations in incorporating and moving large molecules, due to constraints in reflux treatment temperatures and gel dissolution during high-temperature processing.
A method involving impregnating a starting gel with an alkaline solution and heating it above 100°C followed by firing, which results in a porous body with micropores and coarse pores having a most frequent diameter of 50.0 nm or more and 500.0 nm or less, respectively, and a total pore volume within specific ranges, using a ceramic skeleton.
The method enables the production of porous bodies suitable for a wide range of applications, including chromatography separation columns and catalyst supports, by ensuring large pore diameters and volumes, enhancing the ability to handle molecules with large molecular sizes.
