Abstract: A catalyst includes a carrier, and a metal obtained by reducing a metal ion supported on the carrier 1) in a supercritical state or 2) in a polar organic solvent, wherein the carrier is an inorganic porous body having a hierarchical porous structure. By employing the catalyst, it is possible to exhibit better catalytic activity than a conventional catalyst. Heat generation and spontaneous ignition are prevented because no organic porous body is used.

Abstract: The present invention provides a porous sustained-release body in which transparency of a porous carrier changes. The porous sustained-release body includes an inorganic monolithic porous body 1 including a skeleton body 2 of an inorganic compound and air gaps 3,4 having a three-dimensional continuous network structure formed in the skeleton body 2, and a sustained-release liquid absorbed into air gaps 2, 3, wherein the inorganic monolithic porous body 1 is opaque at an initial state, which is a state before absorption of the sustained-release liquid in which air exists in the air gaps, and refractive index of the sustained-release liquid and refractive index of the skeleton body are the same within an error range within which a portion in which the sustained-release liquid is absorbed into the air gaps changes to transparent or semitransparent.

Abstract: Provided is a producing method that makes it possible to stably manufacture a homogeneous titania monolithic porous body by a sol-gel method using various titanium alkoxides as a titanium precursor. The method comprises the steps of; preparing a titanium precursor solution by mixing a titanium alkoxide other than titanium methoxide, which is a titanium precursor, and a first anion source in an organic solvent; preparing a sol by adding water or an aqueous solution containing a second anion source to the titanium precursor solution; forming a co-continuous structure of a titania hydrogel phase and a solvent phase by subjecting the sol to sol-gel transition and phase separation in parallel; and removing the solvent phase from the co-continuous structure, in which a temperature lower than the boiling point of the compound having the lowest boiling point present in the titanium precursor solution is maintained in the first three steps, and in which a blending amount of the first anion source or that of the first and the second anion sources is set such that a molar ratio of the first anion source or a molar ratio of the first and the second anion sources in total to the titanium precursor is equal to or higher than 1.05.

Abstract: A method for reacting a reaction object with a liquid containing the reaction object in contact with a granular porous body. The upper limit D (mm) of the particle diameter of the granular porous body is determined from D=0.556×LN (T)+0.166 in a column flow method in non-circulation type, and determined from D=0.0315×T+0.470 in the column flow method in a circulation type and a shaking method. The granular porous body includes a skeleton body including an inorganic compound having a three-dimensional continuous network structure, and has a two-step hierarchical porous structure including through-holes formed in voids in the skeleton body, and pores extending from a surface to an inside of the skeleton body and dispersed on the surface. A functional group having affinity with the metal ion is chemically modified on a surface of the granular porous body.

Abstract: The present invention provides efficient reaction conditions by clarifying a relationship between a contact time and an optimum particle diameter etc. in a method for reacting a reaction object with a liquid containing the reaction object being in contact with a granular porous body. The upper limit D (mm) of the particle diameter of the granular porous body is determined from D=0.556×LN (T)+0.166 in a column flow method in non-circulation type, and determined from D=0.0315×T+0.470 in the column flow method in a circulation type and a shaking method. The contact time T (seconds) is given by a value obtained by dividing the volume (m3) of the granular porous body by the flow rate (m3/second) of the liquid in the column flow method in non-circulation type, given by a value obtained by multiplying the fluid flow time (seconds) of the liquid by a volume ratio obtained by dividing the volume of the granular porous body by the volume of the liquid in the column flow method in a circulation type, and given by a value obtained by multiplying the volume ratio by the elapsed time (seconds) after addition of the granular porous body in the liquid in the shaking method.
