  • Oxygen evolution catalyst
    Patent number: 10879538
    Abstract: An oxygen evolution catalyst includes a core and a shell covering the surface of the core. The core includes ruthenium oxide or metal ruthenium in at least a surface portion. The shell includes titania or a composite oxide of titanium and ruthenium. Such an oxygen evolution catalyst is obtained by (a) dispersing core particles each including ruthenium oxide or metal ruthenium in at least a surface portion in a solvent to obtain a dispersion, (b) adding a Ti source to the dispersion to produce precursor particles in which the surface of each core particle is covered with a titania precursor, and (c) collecting the precursor particles from the dispersion and heat-treating the precursor particles after drying.

  • NON-VOLATILE PHOTONIC MATERIAL AND PRODUCTION METHOD OF THE SAME
    Publication number: 20160187536
    Abstract: A photonic material capable of reflecting part of the light rays in a wavelength region from near-ultraviolet light to near-infrared light. The photonic material contains a block copolymer including a plurality of different polymer chains connected to one another. Each polymer chain independently forms a portion of an aggregated nanophase separated structure. At least one of the plurality of polymer chains is swelled with a non-volatile solvent. An example of such a photonic material may be a polystyrene-b-poly(2-vinylpyridine) block copolymer whose poly(2-vinylpyridine) phase is swelled with an ionic liquid.
