摘要:
The present invention provides a nanocrystal tandem catalyst comprising at least two metal-metal oxide interfaces for the catalysis of sequential reactions. One embodiment utilizes a nanocrystal bilayer structure formed by assembling sub-10 nm platinum and cerium oxide nanocube monolayers on a silica substrate. The two distinct metal-metal oxide interfaces, CeO2—Pt and Pt—SiO2, can be used to catalyze two distinct sequential reactions. The CeO2—Pt interface catalyzed methanol decomposition to produce CO and H2, which were then subsequently used for ethylene hydroformylation catalyzed by the nearby Pt—SiO2 interface. Consequently, propanal was selectively produced on this nanocrystal bilayer tandem catalyst.

A method for producing a fine particle dispersion includes the steps of reducing a metal ion to form a fine particle dispersion aqueous solution; adding an aggregation accelerator into the fine particle dispersion aqueous solution so that agglomerated or precipitated fine particles are separated to obtain fine particles; and re-dispersing the fine particles into an organic solvent containing an organic solvent having an amide group, a low boiling point organic solvent having a boiling point between 20° C. and 100° C. at a normal pressure, and an organic solvent having a boiling point higher than 100° C. at a normal pressure and containing an alcohol and/or a polyhydric alcohol.

A developer supply container detachably mountable to a developer supply apparatus including a container body, for accommodating developer, including a discharge opening for permitting discharge of the developer therefrom, coupling device, disposed connectable to a coupling member of the developer supply apparatus, for rotating the container body, feeding device for feeding the developer toward the discharge opening in the container body by the rotation of the container body, and regulation device, disposed at a peripheral surface of the container body, for regulating mounting of the developer supply container on the basis of whether or not it is substantially fitted with a regulation member of the developer supply apparatus. After the developer supply container is set to the developer supply apparatus, the regulation device is capable of rotating the regulation member of the developer supply apparatus by a rotational force received by the coupling device while retaining engagement of the regulation device with the regulation member.
