Abstract: An electrocatalyst based on a highly electroconducting polymer and a transition metal, in which transition metal atoms are covalently bonded to heteroatoms of the backbone monomers of the polymer. The covalently bonded transition metal atoms are nucleation sites for catalytically active transition metal particles. The complex is prepared by complexing a highly electroconducting polymer with transition metal coordination ions and then reducing the transition metal ions to neutral atoms. An electrode for a fuel cell is made by impregnating an electrically conducting sheet with the catalytic complex and drying the impregnated sheet. The scope of the present invention includes such electrodes and the fuel cells that incorporate these electrodes.

Abstract: A photocatalytic functional material having an excellent photocatalytic activity even by a low temperature heat treatment and having a high mechanical strength of the surface. The photocatalytic functional material of the present invention comprises a surface layer (a photocatalytic functional layer) containing a photocatalyst, an electron trapping metal and a photodegradation-resistant matrix. Though the major proportion of the photocatalyst (TiO2 particles, and the like) in the photocatalytic functional layer are covered with the photodegradation-resistant matrix (a thermosetting resin, and the like), the electron-trapping metal effectively traps the electrons generated by the photocatalytic reaction, retains positive holes and generates active oxygen species, so that the photocatalytic function such as deodorant and antimicrobial activities can be fully exhibited.
