摘要:
A titanium oxide photocatalyst having metal ions of one or more metals incorporated therein selected from the group consisting of Cr, V, Cu, Fe, Mg, Ag, Pd, Ni, Mn and Pt, wherein the metal ions are implanted from the surface to deep inside of the bulk of the photocatalyst in an amount of at least 1.times.10.sup.15 ions per g of the titanium oxide; a process for producing the photocatalyst; and a photocatalytic reaction method using the photocatalyst.
摘要:
A graft copolymer membrane prepared by co-grafting a mixture of monomers consisting essentially of acyloxystyrene and/or hydroxystyrene, a polyene compound and at least one member selected from the group consisting of acrylic acid, methacrylic acid and esters of these acids onto a hydrocarbon type of fluorine-containing type polymer by means of ionizing radiation exhibits improved mechanical strength and reduced electrical resistance and provides an excellent ion-exchange membrane.
