Oxysulfide photocatalyst for decomposition of water by visible light

   
   

A photocatalyst which comprises an oxysulfide containing at least one transition metal; a preferable photocatalyst which also comprises a rare earth element such as Sm in addition to the above and wherein the transition metal is at least one selected from the group consisting of Ti and Nb; a more preferable photocatalyst which further comprises a promoter comprising a transition metal such as Pt loaded on each of the above photocatalyst; and a catalyst for use in the decomposition of water by a light which comprises one of the above oxysulfide photocatalysts.

Un photocatalyst que abarca un oxisulfuro que contiene por lo menos un metal de la transición; un photocatalyst preferible que también abarca un elemento de la tierra rara tal como SM además del antedicho y en donde el metal de la transición es por lo menos uno seleccionado del ti del grupo y de la NOTA que consisten en; un photocatalyst más preferible que abarca más lejos a promotor que abarca un metal de la transición tal como pinta cargó en cada uno del photocatalyst antedicho; y un catalizador para el uso en la descomposición del agua por una luz que abarca uno de los photocatalysts antedichos del oxisulfuro.
