Photocatalyst laminate
A photocatalyst laminate which is composed of an undercoat layer provided on a substrate and a photocatalyst layer laminated on the surface of the undercoat layer. The undercoat layer contains (A) 100 parts by mass of a resin component and (B) 0.1-50 parts by mass of fine core-shell particles, each of which has a core that is formed of a fine tetragonal titanium oxide solid solution particle wherein tin and manganese are solid-solved and a shell that is formed from silicon oxide on the outside of the core. This photocatalyst laminate is not susceptible to decrease in the photocatalyst function even under outdoor exposure for a long period of time, and is thus capable of providing a coated article that exhibits excellent weather resistance.
HYBRID MATERIAL AND METHOD FOR THE PRODUCTION THEREOF
The invention relates to a material in the form of a cellular solid monolith consisting of an inorganic oxide polymer. Said monolith comprises macropores which have an average size d.sub.A of 4 μm to 50 μm, mesopores that have an average size d.sub.E of 20 to 30 Å, and micropores which have an average size d.sub.1 of 5 à 10 Å, said pores being interconnected. The inorganic oxide polymer has organic groups R of formula —(CH.sub.2).sub.n—R.sup.1, wherein 0≤n≤5, and R.sup.1 is selected from among a thiol group, a pyrrole group, an amino group having one or more optional, optionally substituted alkyl, alkylamino, or aryl substituents, an alkyl group, or a phenyl group optionally having an alkyl-type substituent R.sup.2. The disclosed material can be used as a substrate for a metal catalyst and for decontaminating liquid or gaseous media.
Heteroatom Ligand, Oligomerization Catalyst Containing Same, and Method for Preparing Oligomer
The present invention relates to a heteroatom ligand, an oligomerization catalyst containing the same, and a method for preparing an oligomer by using the same. Specifically, the present invention relates to a heteroatom ligand having a silsesquioxane derivative, an oligomerization catalyst containing the same, and a method for preparing an oligomer by using the same.
