A silicon nanoparticle-containing hydrogen polysilsesquioxane sintered product–metal oxide complex comprising a silicon nanoparticle-containing hydrogen polysilsesquioxane sintered product and a metal oxide, wherein the silicon nanoparticle-containing hydrogen polysilsesquioxane sintered product contains 5 wt% to 95 wt% of silicon nanoparticles having a volume-based mean particle size of more than 10 nm but less than 500 nm, and a hydrogen polysilsesquioxane-derived silicon oxide structure that coats the silicon nanoparticles and is chemically bonded to the surfaces of the silicon nanoparticles. The silicon nanoparticle-containing hydrogen polysilsesquioxane sintered product is represented by the general formula SiO x H y (0.01 < x < 1.35, 0 < y < 0.35) and has Si–H bonds. The metal oxide consists of one or more metals selected from titanium, zinc, zirconium, aluminum, and iron. |
