Embodiment 1

[0457] [Example 1]: phloroglucinol+silica particles+250°C×1 hour

[0458] Phloroglucinol (manufactured by Tokyo Chemical Industry Co., Ltd., melting point: 220°C, condensation reaction temperature: 330°C, theoretical specific surface area: 750m 2 / g) with silica particles (manufactured by Fuji Silysia Chemical Ltd., product name: "Q-10HT60315", specific surface area: 259m 2 / g) Mix well so that the thickness of the phloroglucinol layer is 1.5 times greater than the thickness of the silica particle layer.

[0459] The resulting mixture was sealed in a quartz ampoule in vacuum, and then heated in an electric furnace preheated to 250° C. for 1 hour.

[0460] Thus, an organic-inorganic composite (1) including the carbon substance (1A) and the inorganic oxide (1B) was obtained.

[0461] The organic-inorganic composite (1) was dispersed in N-methylpyrrolidone (NMP), and the solubility of its carbon component was confirmed by the means described in the foregoing. As a result, this...

Embodiment 2

[0468] [Example 2]: phloroglucinol+alumina particles+250°C×1 hour

[0469] In addition to changing the silica particles to alumina particles (sample "JRC-ALO7" distributed free of charge by the general corporate juridical person "Japan Society of Catalysis", specific surface area: 180m 2 / g), an organic-inorganic composite (2) including a carbon substance (2A) and an inorganic oxide (2B) was obtained in the same manner as in Example 1.

[0470] The organic-inorganic composite (2) was dispersed in N-methylpyrrolidone (NMP), and the solubility of its carbon component was confirmed in the manner described in the foregoing. As a result, this component is soluble in the solvent.

[0471] The results of the C1s XPS analysis of the obtained organic-inorganic complex (2) are shown in image 3 (XPS Spectrum (C1s)) and Table 1. From Table 1, it was found that the organic-inorganic composite (2) was an organic-inorganic composite including carbon substances and inorganic oxides. The ...

Embodiment 3

[0476] [Example 3]: phloroglucinol+titanium dioxide particles+250°C×1 hour

[0477] In addition to changing the silica particles to titanium dioxide particles (sample "JRC-TIO-4(2)" distributed free of charge by the general corporate juridical person "Japan Society of Catalysis", specific surface area: 50m 2 / g), an organic-inorganic composite (3) including a carbon substance (3A) and an inorganic oxide (3B) was obtained in the same manner as in Example 1.

[0478] The organic-inorganic composite (3) was dispersed in N-methylpyrrolidone (NMP), and the solubility of its carbon component was confirmed by the means described in the foregoing. As a result, this component is soluble in the solvent.

[0479] The results of the C1s XPS analysis of the obtained organic-inorganic complex (3) are shown in image 3 (XPS Spectrum (C1s)) and Table 1. From Table 1, it was found that the organic-inorganic composite (3) was an organic-inorganic composite including carbon substances and ino...

Abstract

Provided is a method for producing, under mild conditions and in a simple manner, a carbon matter-containing material having a precisely controlled structure. Also provided is a carbon matter-containing material in which a carbon matter and an inorganic substance are covalently bonded. Further provided is an intermediate material that can be produced industrially under mild conditions and that is useful for, for example, industrially manufacturing carbon-coated inorganic particles, hollow carbon microparticles, and the like. The carbon matter-containing material production method comprises a heating step (I) for heating a composition that contains an inorganic substance and a compound (A) in which, by heating, a condensation reaction takes place between molecules of the same type and / or between dissimilar molecules, wherein the heating temperature during the heating step (I) is at least (T-150) DEG C. The carbon matter-containing material comprises a carbon matter and an inorganic substance, wherein at least a portion of the carbon matter and at least a portion of the inorganic substance are covalently bonded. The organic-inorganic composite according to the present invention comprises a carbon matter and an inorganic substance, wherein the carbon matter is soluble in a solvent.

Description

technical field [0001] The present invention relates to a method for producing a carbon-containing material, a carbon-containing material and a soluble organic-inorganic composite. Background technique [0002] In consideration of recent trends of resource saving and energy saving, lightweight carbon materials have been developed and used in various fields. For example, materials containing carbon substances, such as carbon-coated inorganic particles and hollow carbon fine particles, have been reported as compounds each including such lightweight carbon materials and usable in various fields (for example, Patent Documents 1 to 4, and Non-Patent Documents 1 to 4, and Non-Patent Documents 1-4). In addition, activated carbon, carbon black, and the like are known as industrially produced carbonaceous materials. [0003] However, it is difficult to apply prior art carbonaceous material materials such as carbon-coated inorganic particles and hollow carbon fine particles to indus...
