Abstract: The present disclosure relates to a nanocrystal composite includes a connected aggregate including a plurality of nanocrystal fragments connected to one another, each nanocrystal fragment having a main surface and an end surface, and nanoparticles supported on the connected aggregate. The plurality of nanocrystal fragments each have a flaky shape; the plurality of nanocrystal fragments have gaps between the main surfaces; and the gaps G are arranged so as to open to the outside of the connected aggregate. The nanoparticles have a metallic element different from that of the plurality of nanocrystal fragments; and a proportion of a visual field area of the nanoparticles with respect to a visual field area of the plurality of nanocrystal fragments is 2% or more and 50% or less.

Abstract: The present disclosure relates to a method for producing metal oxide nanoparticles includes a first step of preparing a reaction solution containing a metal complex, an alcohol, and water; a second step of heating the reaction solution for phase-separation under a hermetically sealed atmosphere where the volumetric expansion ratio of the reaction solution reaches 5 to 15%; a third step of holding the reaction solution heated in the second step for 30 minutes or more for dehydrating the metal complex to precipitate the metal oxide nanoparticles; and a fourth step of collecting the metal oxide nanoparticles after the metal oxide nanoparticles are cooled.
